Yes, this prehistoric fish actually had a buzzsaw of spiraling teeth

Scientific Method / Science & Exploration

It takes an artist to capture the true weirdness of the ancient animal's face.

LOOK INTO MY TEETH AND DESPAIR.
Nicknamed the "buzzsaw shark," this 270 million-year-old creature is actually an extinct relative of the ratfish called a Helicoprion. Its bizarre tooth arrangement has confused scientists for over a century, but one artist finally got it right.
Ray Troll, whose art show about Hilicoprion has been touring the US for the past three years, has been on the front lines of scientific research about one of the strangest fossils ever found. When geologist Alexander Petrovich Karpinsky discovered the creature's tooth whorl in 1899, at first he thought it was a kind of ammonite because the teeth looked so much like the ammonite's spiral shell.
Paleo expert Brian Switek writes that it took Karpinsky a little while to realize that it was actually part of a larger animal. Over the next century, many different paleontologists offered explanations for what it might be, including a defensive formation on Helicoprion's nose, a ridge on its back, or even sticking out of its mouth like a spiky, curled tongue.

explain where Helicoprion's spiral teeth were positioned.
Over at the Smithsonian, there's a great profile of Troll, who has done
a lot more than make art of this crazy fish. He's actually added to the
scholarship on it:
Troll’s passion, however, has served a purpose far beyond the aesthetic charm of a framed picture—it has shaped the scientific community’s knowledge of Helicoprion itself. Back in the mid-1990s, when he wrote and spoke with [paleontologist Svend Erik Bendix] Almgreen, Troll discovered that the scientist had published his hypothesis about the buzz shark’s physiology in an obscure paper in 1966. This knowledge remained hidden, lost to memory even to prominent paleontologists, until 2010, when an undergraduate student working as an intern at the Idaho Museum of Natural History got in touch with Troll.
As a result, Troll began working with paleontologist Leif Tapanila, who used used CT scans to image a whole skull of a Helicoprion—revealing that the buzzsaw shape was actually part of its lower jaw, used for slicing food and pushing it toward the back of the fish's mouth. It seems that the teeth formed in the jaw next to the topmost part of the spiral, then gradually worked their way down and back into the jaw. Once there, the teeth would be absorbed into cartilage and eventually turned into teeth again. These scans became the basis for an article published in 2013 in Biology Letters, which also included some of Troll's artwork of the buzzsaw in its rightful place.

Troll's drawings and sculptures, which are still touring the US today (currently they are at the University of Oregon's Museum of Natural and Cultural History), are a reminder that paleoartists contribute a great deal to scientific discovery. Taking a whimsical approach, Troll called his show "The Buzz Sharks of Long Ago." His goofy humor is a perfect way to shine light on the truth of natural history, which is often so weird that it might as well be art.

Man killed in shark attack while fishing in Hawaii

CNN Explains: Shark attacks

STORY HIGHLIGHTS
  • The man was fishing from a kayak when a shark bit his dangling foot
  • His companion tried to save him, but he died on the way to shore
  • This is the 13th shark incident in Hawaii so far this year, authorities say
(CNN) -- A man fishing from a kayak off a Hawaiian island has died after being bitten by a shark, authorities said Monday. The incident was the latest in an alarming spate of shark attacks in the state this year.
The attack took place Monday morning half a mile off a point near Little Beach in Makena State Recreation Area on the island of Maui, the Department of Land and Natural Resources (DLNR) said.
The victim's companion, who was also on a kayak, told the department that his friend was fishing for baitfish with artificial lures when a shark bit one of his feet, which was dangling over the edge of the boat.
Shark victim's foot dangled over boat
The man's companion, who was about 500 yards away when the attack took place, paddled over to him, tied a tourniquet to try to stem severe bleeding and called on a tour boat in the vicinity for help, authorities said.
The tour boat brought the man to shore, and he was then taken to the hospital. But authorities believe he died of his injuries during the boat journey, said Rod Antone of the Mayor's Office of the County of Maui.
The man was in his 40s, but authorities are unsure if he was a local resident or a tourist, Antone said. The identities of the man and his companion have not been disclosed.
High number of shark incidents
"We offer our condolences to the family of the victim. Our thoughts and prayers are with them," said William J. Aila, Jr., the DLNR chairman.
Authorities say they have closed the waters off Makena State Recreation Area following the attack. Beaches in the area remain open, but the DLNR said people are advised to stay out of the water.
The area will reopen at noon Tuesday if no more sharks are seen in the vicinity, the department said.
The attack is the 13th shark incident reported in Hawaii so far this year, and the eighth on Maui, authorities said.
That's well above the state's average of four unprovoked shark attacks per year over the past 20 years. The 10 incidents reported in 2012 were unprecedented at the time, the DLNR said.
"We are not sure why these bites are occurring more frequently than normal, especially around Maui," Aila said. "That's why we are conducting a two-year study of shark behavior around Maui that may give us better insights."
Aila said that authorities hope and expect "that numbers of incidents will return to a more normal range in the near future."
In August, a German tourist died after being bitten by a shark while she was vacationing in Hawaii.

Shark Victim Feared Something Was 'Down There' in Dark Murky Waters

A Florida woman attacked by a shark said today that before she got into the water she told her friends she was uneasy about getting into the dark water "because you can't see what's down there."
What was down there was a shark that ripped into her leg and then swatted her in the face with its fin.
Jessica Vaughn, 22, of Coral Springs, Fla., was attacked Sunday afternoon, but was well enough today to smile through a news conference and even joke about it.
She probably won't get back into the ocean soon, however.
"It was really scary. Before we went out, I said I don’t like going into the water... when I can’t see what’s down there," Vaughn said at the Broward Health Medical Center. She added, "I've always had feelings of something down under there because of the dark murky waters."
Vaughn said, "I feel very lucky. I wouldn't go back in that kind of water anymore."
She was going tubing with friends at the home of Peter Hogge around 1:30 p.m. Sunday. She said she was swimming on her back to the tube when she was attacked by the shark.
"At first I felt like something punched my leg," Vaughn said. "I thought a fish bit me. Then I saw my leg was cut open. I realized it wasn't a fish."
"I thought I would be fine once I get into the tube," Vaughn said.
"It came up from behind her and bit her leg and then kind of smacked its tail and most of its body out of the water, hit her in the face actually, and took off," Peter Hogge told ABC News affiliate WPLG.
RELATED: When Animals Attack
"Her friends immediately pulled her back on the boat and bandaged her," Timothy Heiser, deputy fire chief at Fort Lauderdale Fire Department told ABC News. The deputy chief said Vaughn's friends likely saved her life by putting pressure on her gash.
"They did a really good job," Heiser said. "She could have lost too much blood and died."
Vaughn's friends raced the boat back to a dock where person on the 11th floor of a nearby condo building heard them screaming and called 911, according to Heiser. Paramedics arrived shortly after and brought Vaughn to Broward Health Medical Center.
A picture of Vaughn's wound was tweeted by the Fort Lauderdale Fire Rescue and it showed the muscle of Vaughn’s right leg was shredded, exposing the bone.
Vaughn underwent two hours of surgery Sunday evening and is reported to be in good condition, according to the hospital.
"She will be discharged from the hospital in two to three days," said Dr. Zoran Potparic, who performed Vaughn's surgery.
Vaughn is expected to recover within three to four months, Potparic said.
"Infection is the very next thing we have to worry about, especially since the coastal water tends to be very polluted," he said.
Vaughn said she is a waitress at a restaurant and doesn't have insurance. She is thankful that social workers at the hospital are looking to see if the Affordable Care Act could cover some of her surgery costs.
"Shark attacks usually happen in northern Florida," Heiser said. "It's quite uncommon in this area."
"This is really the first shark attack that I've ever heard of," said Brian Hogge, Peter Hogge's cousin who directed Vaughn to the dock. "I've seen sharks before and there are a lot of water skiing activities going on. But this is really the first time (a shark attack happened)."
Peter Hogge has set up a fundraiser on Gofundme.org to raise money for his friend's recovery.

Great white shark bites inflatable boat as worried crew hopes for the best

The Big Blue Ocean Exploration

Vessel does not sink and crew gets safely away in incident off South Africa

Great white shark sinks teeth into rubber boat; image is a video screen grab
Video showing a great white shark repeatedly biting an inflatable boat before its wide-eyed crew is being widely shared this week, along with sensational headlines such as this from the Daily Mail:
“Let go of the boat, Jaws! Terrifying moment great white shark sunk its teeth into a rubber dinghy in the middle of the sea.”
And this from Huffington Post: “Shark mistakes inflatable boat for chew toy.”
Actually, it was quite a spectacular incident last month off South Africa. But the MaxAnimal film crew did not seem overly concerned as the shark teethed on and ultimately popped one of the vessel’s pontoons.
MaxAnimal wrote in its video description: “Is the scariest part when the shark eyes our folks on the boat? Ah, yeah.”

Great white shark takes another bite in what appears to be investigatory behavior; image is a video screen grab
But the boat did not sink–it can be seen motoring away at the end of the video–and nobody was injured, according to a YouTube comment by MaxAnimal.
But why was the shark biting their boat?
Amber Marlow was probably accurate when she commented: “Not an ‘attack’ – he was just exploring the boat, and subsequently chomped it to death out of curiosity.”
More than likely, the crew used chum to lure the shark to the boat, and once the shark was close it was simply being a shark by investigate potential prey.
“No uncommon behavior,” Christopher Lowe, a white shark expert at Cal State University, Long Beach, told GrindTv. “But, staying near an adult white shark in an inflatable boat is not a smart move. Expensive rookie mistake!”
Added Martin Graf, whose Shark Diver company specializes in great white shark expeditions at Mexico’s Guadalupe Island:
“I think they had a bait in the water that got the shark close. The vibrations from the engine make it appear alive and the shark is testing it, to see if it is edible. They also bite outboard engines, because of electrolysis that comes from it, for the same reason.”
So it’s good for the crew that the shark was simply investigating. Had the boat been much smaller the shark might have chosen to launch an ambush attack. That would have been truly sensational.

Rare Goblin Shark Caught By American Shrimp Fisherman

Posted: Updated:
This fisherman's catch is goblin up the headlines.
A Florida shrimper accidentally caught an incredibly rare Goblin Shark off the coast of Key West, Florida, on April 19, according to the Houston Chronicle.
"I didn't even know what it was," fisherman Carl Moore said. "I didn't get the tape measure out because that thing's got some wicked teeth, they could do some damage."
Instead, Moore snapped some quick photos and threw the shark back in the ocean.
Story continues below horrifying looking shark ...

Moore didn't report the find to the National Oceanic and Atmospheric Administration until Thursday. According to the NOAA, the 18-foot-long shark is only the second ever seen in the Gulf. It is "one of the rarest species of sharks," according to NOAA.
Goblin sharks are most commonly found off the coast of Japan, the Chronicle reports. They are "pinkish white" in color with bluish fins, according to NOAA.

This 805-Pound Shark Went From the Top of the Food Chain to Being Served at a Florida Barbecue

Takepart.com
Mon, 21 Apr 2014 13:16:26 PDT

It’s not every day that you see an 11-foot-long, 805-pound shark at a gas station. But last week after Pensacola Beach, Fla., resident Cat West stopped for a fill-up and saw a ginormous fish hanging out of the back of a pickup truck, he snapped a photo that lit up social media. Now two Florida cousins are being lauded for possibly setting a world record for largest shortfin mako catch ever.
Earnie and Joey Polk, two fishermen who hold records from the International Land-Based Shark Fishing Association, say they intended to keep the catch a secret—they don't want their angling spots swarmed by record-seeking competition. But this particular shortfin mako was simply too large to stay hidden in the bed of their pickup.
“That’s probably the best fish we ever caught,” Earnie Polk told the Pensacola News Journal. “You’ll spend many, many hours to catch a fish of that caliber or a fish of that size.” Torpedo-like shortfin makos are known for being the fastest shark in the sea. They've been clocked at speeds of up to 60 miles per hour. They can also leap 20 feet in the air. 
The duo say they normally tag and release the majority of sharks they catch (in 2013 they caught 300 sharks and kept 20 of them) as part of the National Marine Fisheries Service’s Cooperative Shark Tagging Program. However, an hour-long fight with a hook wore out this particular shark too much for it to survive. In the above video you can see the big fish frantically flopping around after being caught.
Last year a study of shark, ray, and cartilage-containing fish species by the International Union for the Conservation of Nature found that only one-third of the species can be considered “safe” from extinction. The shortfin mako is one of the fish listed on IUCN’s Red List as “vulnerable” globally.
The shark the Polk cousins caught may have once been at the top of the ocean food chain, but it ended up being fried and served at a community barbecue. Shortfin makos are, along with other shark species, targeted across the world for both their meat and their fins. One hundred million sharks die every year.
Earnie Polk said what they do is “just a good pastime.” He said he and his cousin fish ethically. “We don’t do chumming whatsoever. We fish at night. We don’t fish on crowded beaches. We don’t fish anytime there are swimmers,” he said. “We don’t draw the fish to the beach. We just catch what swims by. The fishermen are there because the fish are there.”

Shark kills woman off Australian east coast

Associated Press

SYDNEY (AP) — A shark killed a woman Thursday as she swam with a group of swimmers off a popular Australian east coast beach, police said.
Christine Armstrong, 63, was taken as she attempted to swim the 600 meters (2,970 feet) between the wharf and beach near the village of Tathra, 340 kilometers (210 miles) south of Sydney, police said in a statement.
The Thathra Wharf to Waves — a swim from the wharf to the beach and back again — is an annual event that attracts hundreds of swimmers each summer.
Local council general manager Leanne Barnes said the victim was part of a group of locals who meet at the beach every morning to swim out to the wharf and back.
"It's a beautiful little coastal village and this is one of those sad things that can happen," Barnes said.
Police said a helicopter and boat were being used to search for remains. No details of the species of shark were released.
Although sharks are common off Australia's coast, the country has averaged fewer than two fatal attacks per year in recent decades. But fatal attacks are becoming more common. Two men were killed in shark attacks off the east and west coasts in the space of a week in November last year. They were the only fatalities for 2013.
Police on Wednesday recovered remains of a 38-year-old man reported missing last week while diving south of the west coast city of Perth. Police said a statement that the remains had shark bites, but it was not clear whether he had been bitten before or after he died.

Shark gives Florida student two-hour ride, stars in YouTube video


Reuters

By Barbara Liston
ORLANDO, Florida (Reuters) - A hammerhead shark dragged a college student in his kayak up the Atlantic coast for a two-hour "South Florida sleigh ride" that the kayaker taped with a head-mounted camera and posted on YouTube.
Adam Fisk, 22, posted a five-minute clip of his adventure titled "Lone Man Gets Towed for Miles in Kayak by 11 Foot Hammerhead Shark."
At one point, Fisk dunked the camera into the water and recorded the shark swimming ahead of the kayak.
A student at Florida Atlantic University, Fisk set out in a kayak on Sunday with several poles to go fishing before the shark took his bait near Boynton Beach, Florida.
"I threw my bait out and went to reel my other one in so I wouldnt get tangled, and I just had time to pick up the rod before the other one already got picked up by that hammer," Fisk wrote on the YouTube site. ( https://www.youtube.com/watch?v=9bToT32GPSo)
"It must have been sitting right under me and I had no idea."
Fisk is a member of Team Rebel Fishing, a group of extreme anglers, according to its website. The group estimated Fisk was dragged by the shark for 12 miles.
Fisk told Reuters that the ride started out smoothly but turned frightening when the shark twice reversed course.
"It would do a 180-degree turn and come straight back at me and that rally scared me because I couldn't see it and I didn't know if it was coming to bite me," he said.
Fisk said he turned his kayak around until the line got taut and the shark began pulling again. He said the shark took him out to sea and around in circles, ending at Lake Worth, Florida.
"Hooked a hammerhead in 50ft of water and got drug out to 250ft," Fisk posted in his Facebook account of the ride under the headline, "I took a South Florida sleigh ride today and I aint talkin Santa Claus."

Anti-shark devices popular on Maui after attacks


Associated Press
.Shark Repelling Devices Gain Popularity
KIHEI, Hawaii (AP) — A surge in shark attacks on Maui over the past year, including two fatal ones, hasn't stopped people from surfing and swimming in the warm ocean waters that surround the Hawaii island.
But it has spurred sales of devices that claim to keep sharks away by emitting an electric pulse.
"They just cannot make these things fast enough," said Hawaiian Island Surf & Sport owner Dennis O'Donnell, who keeps a waiting list for the products and sells out as soon as he's restocked.
Users strap the devices to their ankles, wetsuits or surfboards. Some are about the size of an oversized watch, others the size of a wallet. They range in price from $399 to $649.
Some shark experts say the devices may help in some cases, but it's questionable whether they'll repel large sharks.
With or without the devices, people need to remember they are taking a risk when they go into waters inhabited by large predators like sharks, said George Burgess, the director of the Florida Program for Shark Research.
"It's not equal to going to the YMCA pool or the pool at the hotel," Burgess said.
The sales spike comes as there have been eight shark attacks in Maui waters last year. Statewide, there were 14 attacks in 2013. There were 11 attacks in Hawaii in 2012 and three the year before.
In August, a German tourist died a week after a shark bit off her arm. In December, a man fishing on his kayak died after a shark bit his foot that was dangling in the water.
The last time anybody was killed by a shark in Hawaii waters was in 2004.
Sterling Kaya, owner of the Honolulu fishing supply store Hana Pa'a Fishing Co., said he used a device once while using a spear to fish in the Marshall Islands.
Without it, sharks ate the catch he and his fellow fishermen strung to a float while they fished, Kaya said. But the sharks stayed away when they attached the device to their catch.
Carl Meyer, a shark researcher at the Hawaii Institute of Marine Biology, said the devices may reduce the risk of a shark bite but won't eliminate it, cautioning that no independent, peer-reviewed studies have been conducted on their effectiveness.
Burgess said the only people who would need one of the devices are those whose jobs put them regularly in direct contact with sharks. People who dive for abalone or sponges in places where sharks are very common might fall into this category, he said.
Spearfishermen may also benefit as they are diving with bloody fish that can attract sharks. But there's still a question of whether the electrical field released by the device will deter the fish they're trying to spear, Burgess said.
Burgess is also skeptical whether the devices will effectively deter large sharks that tend to be the types involved in fatal attacks on humans — like tiger, white or bull sharks.
Even so, he noted the odds of getting bitten by a shark are tiny. People are much more likely to drown or have a heart attack in the water than be attacked by a shark, he said.
Dan Peters, who visited Maui from Kirbyville, Texas, said hearing about the shark attacks concerned him, but it didn't stop him from going in the ocean.
"I know they're not out there specifically looking for me," he said.

Surge in shark attacks causes alarm in Hawaii

MAKENA STATE PARK, Hawaii — After a record year of attacks across the Hawaii archipelago, sharks were not far from Colin Dececco's mind as the sun went down on the long white strip of sand here on a recent Sunday evening.
He and his daughter had had a close encounter with a reef shark while swimming around the rocky cove at the north end of Makena's Big Beach that morning. Now, watching a spear fisherman haul in his catch as they strolled by the same spot at sunset, they heard a splash at the edge of his net.
It was an 8-foot tiger shark, one of the most aggressive shark species in Hawaii's waters and the likely culprit for many of the 14 attacks in 2013, eight of which occurred around Maui, near Makena's beaches and elsewhere. Releasing his net, the fisherman took off running down the shoreline, shouting for swimmers to get out of the water.
PHOTOS: Sharks too close for comfort
"By then everyone was kind of running," Dececco said in an interview moments after he and his daughter had scrambled up the rocky cliff above the cove for a better view. "Tiger sharks — you don't play with them."
In a state where tourism drives the economy, the uptick in shark encounters has alarmed visitors and business owners alike. Both 2013 fatalities — a German snorkeler and a Washington state kayak fisherman — occurred in the waters near Makena State Park. But there are no permanent warning signs here on a coastline that boasts luxury hotels including the Four Seasons Resort Maui and the Waldorf Astoria's Grand Wailea.
For years, the state Department of Land and Natural Resources has posted signs and closed the beach immediately after an attack until noon the next day, if officials on helicopter and jet ski patrols believe the shark has left the vicinity. And for now, they see no need to change that policy.
"There is no pattern. There are spikes; there are lulls," said William Aila Jr., the department's chairman. But shortly after the German tourist died in August, the state agency announced a two-year, $186,000 study by University of Hawaii researchers to determine whether tiger sharks spend more time in areas used for ocean recreation around Maui than the other islands.
So far, the increases in attacks in 2012 and 2013 — which followed three years in which there were just three shark attacks annually — do not appear to have affected tourism. More than 2.1 million people visited Maui last year, figures that Terryl Vencl, executive director of the Maui Visitors Bureau, said she had not seen since before the recession.
"I think people realize it is still a rare occurrence," Vencl said in an email.
There is no question, however, that many swimmers and snorkelers are adjusting their routines based on the location of encounters. No pattern has emerged linking the likelihood of an attack with the distance from shore: The kayak fisherman was 900 yards off Makena; the German snorkeler was 50 yards offshore. But a number of tourists said in interviews that they were not swimming out as far.
"I went in waist-deep, that was it," said Karen O'Brien, a 49-year-old tourist from Toronto. Last year, O'Brien snorkeled off Molokini, a small island off the southwest coast of Maui. But after reading that the kayak fisherman was attacked near Molokini, she said, "I wasn't interested."
Island native Lorraine Alesna, who has long fished at Makena Landing — a popular launching spot for kayakers and snorkelers — shook her head at the jet skiers, kite surfers and other tourists who zoomed into the waves without paying attention to pupping season for sharks (the winter months), or common-sense tips like avoiding turbid water that attracts them.
"People that come from the mainland have no respect for anything, neither the ocean nor the land," Alesna said. "We grew up knowing, by the elders, what we can and cannot do in certain times of the year."
Like many longtime residents and fishermen here, Alesna offers myriad theories for the rise in shark attacks. She questions whether the tsunami in Japan increased the level of radiation in the water, driving sharks closer to shore. (State officials say radiation levels are normal.) She argues that the recovery of the population of Hawaiian green sea turtles — protected under the Endangered Species Act since 1978 — is luring sharks closer to the beach, and she says it's time for officials to allow hunting the turtles again.
But Carl Meyer, a marine biologist leading the University of Hawaii study, said there was no evidence to support that theory, or many of the others he had heard. Turtles, for example, are just one part of the broad diet favored by tiger sharks, which are known as the "garbage cans" of the ocean. He also dismisses the frequently cited notion that there are more tiger sharks in the water and that they are hungrier than in past years.
One known fact, Meyer said, is that there are more kayak fisherman, kite surfers and paddle boarders than a few decades ago — and the study will look at whether tiger sharks are more prevalent in areas of Maui where those sports are most popular.
A website where people can track the movements of the sharks tagged by Meyer and his team has fascinated many tourists and other ocean visitors. Both the state and the university hope it will generate curiosity about sharks, rather than fear, in the midst of renewed debate over whether there should be a shark culling program, which would face fierce resistance among native Hawaiians who consider sharks to be a sacred protector.
The fact that are very few shark attacks relative to how many millions of people are in the water is something of a credo here — from waiters to dive guides, locals are quick to point out that visitors are more likely to die in their cars on the way to the beach.
Minutes after the recent sighting of the 8-foot tiger shark off Big Beach, bolder swimmers were back in the water there and at adjacent Little Beach, a nude sunbathing spot where hundreds of people gather on Sunday nights for a drum circle.
Tadd Laton, a 20-year-old waiter who moved to Maui from San Jose, watched the night swimmers from the cliff overlooking the Little Beach drum circle. After the attacks, locals wouldn't be in those waves at night, Laton said, and he now follows that rule too.
Still, he says he refuses to be cowed. "Life could end at any moment," Laton said. "If I die from a shark attack, that would be a cool way to die." But, he added, "if I see one, I'm going to head right back to shore."

Photo Captures Apparent Encounter With Shark at Manhattan Beach


  • June Emerson made a startling discovery while reviewing the photos she took during a visit to Manhattan Beach on Friday.
    Among the images is one that shows her 12-year-old son Quinn and his friend, both with their surfboards, in front of a breaking wave – and what appears to be a rather sizable shark.

    “It was quite a shock to see” the photo, June Emerson said.
    “Many local surfers and lifeguards have seen this and believe it to be a shark,” she said. “Of course, I told my kids it was dolphin, as we live at the beach and are in the waters here almost daily.”
    Sightings of great white sharks are not uncommon near Manhattan Beach.

    Shark Kills Kayaker in Attack off Maui


    A kayak fisherman died Monday after a shark attack off Maui, local officials said.
    Maui County Ocean Safety officials received a report that a shark attacked a man fishing in a kayak between Maui and Molokini, a small island less than 3 miles off the southwest coast of Maui that's popular for diving and snorkeling.
    Maui County police identified the man as Patrick Briney, 57, of Stevenson, Wash.
    The shark bit his dangling foot while he fished with artificial lures to attract baitfish, a news release from the state Department of Land and Natural Resources said.
    His fishing partner in another kayak tied a tourniquet on the man and sought help from a nearby charter tour boat. The boat took them to shore, and the man was then taken to a hospital, the state said.
    The kind of shark involved was not immediately available.
    Though the attack happened far from shore, the state advised the public to stay out of the water a mile north and a mile south of Makena State Recreation Area in southwest Maui.
    There have been eight shark attacks near Maui this year and 13 statewide. On Friday, a woman suffered nonfatal injuries in a Maui attack.
    "We are not sure why these bites are occurring more frequently than normal, especially around Maui," said department Chairman William Aila Jr. "That's why we are conducting a two-year study of shark behavior around Maui that may give us better insights."
    Over the last 20 years, Hawaii has averaged about four unprovoked shark incidents per year, the state said.
    In August, a German tourist died a week after losing her arm in a shark attack. Jana Lutteropp, 20, was snorkeling up to 100 yards off a beach in southwest Maui when the shark bit off her right arm.
    Before Lutteropp's death, the last shark attack fatality in Hawaii was in 2004, when a tiger shark bit Willis McInnis' leg while he was surfing in Maui.
    Isaac Brumaghim knows firsthand the dangers of kayak fishing, which he said is growing in popularity. He was fishing off Oahu's west coast in April when a camera mounted on his kayak captured footage of a 9-foot shark jumping up and chomping on the tuna he was reeling in.
    Sharks are "an absolute danger, every single day," he said. "You have to respect the fact they can bite you at any time."
    He said bait in the water can easily attract the animal.
    "Just a little bit of blood, a little meat in the water, that's all you need," he said. "It's like dogs out there."

    Mark Quartiano has caught thousands of sharks, and hooked clients up with thousands more. In fact, the Florida captain is famously known as Mark the Shark.
    But until Saturday, Mark the Shark had not encountered anything quite like the monstrous skate that he described as looking “like some kind of dinosaur.”
    It was a rare catch for an angler, indeed. Quartiano said this shark relative’s scientific name is Dactylobatus clarkii, and a quick Internet search revealed very little information about the species. However, on Monday, George H. Burgess of the Florida Museum of Natural History identified the creature as a roughtail stingray with the scientific name, Dasyatis centroura.

    It resides in deeper continental shelf waters of the U.S. East Coast from off the Carolinas south to Uruguay, and in the eastern Atlantic.
    “Most anglers don’t bottom-fish in these deeper waters so they aren’t routinely seen by that user group, but commercial longline fishers and research biologists see the critter fairly commonly,” Burgess said. “Obviously large adults like this require heavy fishing gear and strong backs–they aren’t great fighters, but they weight a bunch and are prone to suck their body onto the bottom like a kiddie arrow tip. Once the suction is broken it’s basically a matter of hoisting up a big weight.”
    Quartiano, who was fishing with a Japanese film crew, had dropped a whole bonito to the bottom off Miami Beach. Before long, line began to spin from his reel.

    “I was fishing at about 500 feet and we were trying to catch a shark for their TV show,” the captain said. “I hooked that monster and it took about four hours to bring it up. At first I thought it was a large thresher shark, because that’s kind of the way they fight.”
    One of the film crew had underwater gear and captured footage that will be released later this year or early next year, Quartiano said.
    Quartiano’s crew winched the giant creature out of the water for “three or four minutes” for a photo opportunity, then set it free. Mark the Shark estimated its weight at 800 pounds.
    “It was a big female and she swam away pretty quickly,” he said. “It was kind of cool to catch something new for a change. … When we first saw it we didn’t know what it was. It looked really odd … like some kind of dinosaur.”

    Mysterious fish with whip-like tail and cone-shaped snout identified as a long-nosed chimaera

    The Big Blue An Outdoor // Nature Blog

    Freakish-looking denizens live at great depths and are rarely encountered; this is only the second ever documented off Canada's Hudson Strait region

    A freakish-looking fish hauled recently from the chilly depths of northeastern Canada has been identified as a long-nosed chimaera.
    The identity of the fish, which boasts a whip-like tail and an enlarged cone-shaped nose, remained a mystery for days after it was captured by Nunavut fishermen in the Hudson Strait.
    That’s understandable because these denizens, although they exist in oceans around the world, inhabit depths of up to 6,000 feet and are rarely encountered.

    Nigel Hussey, a researcher with the Ocean Tracking Network, solved the mystery and told Canada’s CBC News that it’s only the second time a long-nosed chimaera has been documented in the region between Canada and Greenland.
    “Potentially, if we fish deeper, maybe between 1,000 and 2,000 meters, we could find that there’s actually quite a lot of them,” Hussey said. “We just don’t know.”
    A photo of the mystery fish was widely circulated on the Internet before it was identified. Some had incorrectly identified the fish as a goblin shark.
    (The accompanying video footage, captured by researchers with the Japan Agency for Marine Science and Technology, shows a live long-nosed chimaera swimming in an unidentified region of the Pacific.)
    Long-nosed chimaeras, which have hideous-looking mouths loaded with sharp teeth, measure to about five feet. They probe the darkness with enlarged snouts that contain sensory nerve endings that aid in the search for prey.
    Since these distant relatives of sharks and rays are rarely encountered and poorly understood, they’re known by several false names, including ghost shark and rat-tail.
    Perhaps it’s good that these fish are rarely encountered, too, because a highly venomous spine can be found on their primary dorsal fin.
    Definitely a creature fit for the abyss.

    Woman Injured in Shark Attack off Australian Coast


    A woman received serious injuries to her arm when she was mauled by a small shark on Monday as she snorkeled off Australia's remote northwest coast, officials said.
    The 60-year-old woman was attacked by a 1-meter (39-inch) reef shark at Turquoise Bay, a picturesque tourist spot south of the coastal town of Exmouth, the Fisheries Department said.
    She had been snorkeling with her partner about 40 meters (yards) from the beach when she was bitten, it said.
    "The couple have reported the shark initially showed signs of aggression toward him, then turned and bit the woman on the arm," the department's Shark Response Unit manager, Lisa Clack, said in a statement.
    The woman would be flown from Exmouth hospital more than 1,200 kilometers (740 miles) to the Western Australia state capital, Perth, for surgery on her right arm, Royal Flying Doctor Service spokeswoman Joanne Hill said.
    Hill described her injuries as serious but not life threatening.
    The beach was closed to the public following the attack and will likely remain closed Tuesday as rangers assess the shark danger, the Fisheries Department statement said.
    Earlier this month, a 55-year-old professional diver was seriously injured by a suspected great white shark near the town of Esperance on the Western Australia southern coast.
    It was the second time diver Greg Pickering found himself in the jaws of a shark. In 2004, he was bitten on the leg while spearfishing near Cervantes, north of Perth.
    Sharks are common in Australian waters, though the nation has averaged just more than one fatal attack per year over the past 50 years.

    Surfer with boxing skills fights off attacking shark

    Jeff Horton says he landed about eight blows in persuading large predator to back off; board now has a crescent-shaped bite, an inch deep

    A surfer on the Hawaiian island of Kauai claims to have used boxing skills to fend off an attacking shark that bit into his board, narrowly missing his leg.
    Jeff Horton (pictured at right) was surfing earlier this week at Pila’a Beach near Kilauea. He told the Garden Island that he saw the shark, presumably a tiger shark, swimming toward him as he sat on his board.
    “It came flying straight toward me,” he said.
    Upon impact, Horton rolled off of his board and onto the shark, which he briefly rode before unleashing a barrage of punches.
    “I started punching as hard as I could,” he said, adding that he landed about eight blows and caused the shark to back off with a knuckle punch to the eye.
    Horton said he used to be a boxer, and that he was just reacting instinctively.
    “I was pretty scared,” he said.
    There were about 10 others in the water, watching the chaotic incident, and many others on the beach, 200 yards away.
    Horton managed to climb back onto his board and paddle ashore. Aside from abrasions on his hands, he was not injured. The surfboard is left with a crescent-shaped bite mark, an inch deep.

    Horton told the Garden Island that he was greeted with a group hug on the beach, and that a tourist gave him $50 and told him to go celebrate.
    The surfer presumably complied, and said he’ll be hanging the board on his wall as a souvenir.
    Will Horton continue to paddle out on another board?
    “I’ll surf the rest of my life,” he said.

    Great white shark shows amazing healing power

    The Big Blue An Outdoor // Nature Blog

    Guadalupe Island predator that endured a savage bite to the head last year astonishes divers by reappearing, with its seemingly fatal wound all but closed; 'I thought I'd never see him again'

    OLYMPUS DIGITAL CAMERA
    A savage bite to the head by an adult great white shark would almost always be fatal–unless another great white shark is at the receiving end of such an attack.
    The top image, captured last week by Rachel Montero of SharkDiver.com, shows a Guadalupe Island great white affectionately known as Chugey. The Shark Diver crew was pleased to see the 15-foot male shark, but surprised that he was still alive and astonished by how quickly his ominous-looking wound was healing.
    The images posted below, captured last year at Guadalupe, show how Chugey looked after another shark had bitten him on the head, removing a large chunk of the gill area.
    OLYMPUS DIGITAL CAMERA
    Martin Graf, Shark Diver chief executive, used before-and-after images of Chugey in a blog post to show viewers how remarkably well Chugey appears to be healing from what was believed to have been a fatal wound.
    “I have to admit that I didn’t think much of his chances to survive this bite and thought I’d never see him again,” Graf wrote of a shark that has now been seen every season at Guadalupe since he was first spotted in 2004. (Chugey is named after Chugey Sepulveda, a San Diego scientist.)
    Of the more recent images showing Chugey swimming as though nothing had happened, with the gaping wound closing nicely, Graf wrote:
    “Look at the amazing difference! There are no veterinarians, no surgeries or stitches, and yet he looks like he’s healing just fine.
    Guadalupe 09-15-12 (17)
    “I’m blown away by their ability to survive injuries that would kill just about any other animal and the weirdest thing is, these nasty injuries don’t even seem to bother them all that much.”
    Guadalupe Island, which is located 165 miles west of Baja California, is a seasonal gathering place for adult white sharks. They often scuffle during mating rituals and for territorial supremacy, and many bear extensive scarring.
    The bite to Chugey’s head, however, was more severe than injuries most Guadalupe shark divers have seen on other sharks.
    As for the divers themselves, most of them smartly observe these magnificent predators from the safety of metal cages.

    Swimmer mauled to death by Great White Shark in front of hundreds of tourists on New Zealand beach as armed police opened fire on the animal at least 20 times

    Adam Strange, 46, attacked at Muriwai beach near Auckland today

    Police fired 20 shots at a great white shark as they tried desperately to save a father killed while swimming off a beach yesterday.
    Adam Strange, 46, an award-winning film and TV director, waved and called for help as the shark dragged him underwater only 200 yards from hundreds of beachgoers.
    Police and lifeguards launched a frantic rescue effort as about four other sharks joined in the attack off Muriwai Beach, north of Auckland, at around 1.30pm.
    The father of one lived locally and was known to the traumatised young lifeguards who joined the fight to save him.
    Pio Mose was in a group fishing on rocks near the beach when he saw a ‘huge’ shark attack the lone swimmer 50 yards from where he was standing.
    ‘All of a sudden we saw the shark fin and next minute, boom, attack him and then blood everywhere on the water,’ said Mr Mose.
    He said the man appeared to struggle with the shark before it swam away – and then it, and  others, came back.
    Mr Mose called the police on his mobile while a friend ran for help.
    He said: ‘He was still alive. He put his head up. We called him to swim over the rock to where we were.
    ‘He raised his hand up and then while he was raising his hand we saw another attack pull him in.’
    Mr Mose said that as blood filled the water, three or four more sharks arrived. The fishermen were forced to watch as the shark carried the man’s body out to sea.
    ‘It’s awful – like a nightmare. I was shaking, scared, panicked.’

    Mr Mose, who said he had never seen sharks before despite fishing in the area for three years, added: ‘All I was thinking was I wanted to jump in the water and help, but I didn’t want to get attacked, too.’
    Police rushed to the scene and officers in a helicopter guided another on board a rubber boat to where the 12ft to 14ft shark was swimming near the victim.
    He then fired around 20 shots into the water, witnesses said. It was unclear if the shark had been killed. Inspector Shawn Rutene said he could not confirm whether the shark that was shot, and which ‘rolled away’ as a result, was involved in the initial attack.

    He refused to say if it was attacking Mr Strange at the time. Police took 30 more minutes to retrieve his body.
    Adventure lover Mr Strange had worked all over the world, according to his website. His short film Aphrodite’s Farm was in ten major festivals and last year won the Crystal Bear award for best short film at the Berlin Film Festival.
    He had also been a finalist at the London International Awards.
    His wife Meg was last night being comforted at their home, not far from the beach.
    His family, some of whom live overseas, said in a statement Mr Strange was a ‘glorious’ person, a ‘great father, husband and friend.’

    Shark brains 'similar to those of humans'

    Shark brains have been found to share several features with those of humans, new research shows, in a discovery hoped could be crucial to developing "repellents" for the killer great white species.

    Great white sharks have killed an unprecedented number of surfers and swimmers off Australia's west coast in the past year.
    The government last month announced a new catch-and-kill policy for sharks that stray too close to beaches after five fatalities in 10 months. But it is also funding research into other measures, including technology to repel them.
    University of Western Australia shark researcher Kara Yopak, who has dissected the brains of more than 150 species, said new studies of the great white shark's brain had revealed important similarities to human brains.
    "Great white sharks have quite large parts of the brain associated with their visual input, with implications for them being much more receptive to repellents targeting visual markers," Ms Yopak said of the research, published in a special edition of the journal Brain, Behaviour and Evolution.
    Most repellents now on the market target the electrosensitive pores on a shark's head which are used to detect the weak currents emitted by prey, by sending a strong electrical signal to drive them away.
    Yopak said studies found this technology could be effective but failed to repel great whites in all cases. Understanding how their brains work could be vital to developing new deterrents, which could be something as simple as marking patterns on surfboards and wetsuits.
    "A shark may recognise a poisonous sea-snake's markings and swim away, for example, and we can use this information to cue a response," she said.
    "It's about understanding how their neurobiology affects their (behaviour)."
    Yopak is part of a multidisciplinary team at the university's Oceans Institute working towards new commercial repellents.
    Most sharks had been found to have brains of the same relative size as mammals or birds, she added, debunking any idea they are "tiny-brained eating machines".
    Sharks are common in Australian waters but deadly attacks have previously been rare, with only one of the average 15 incidents a year typically proving fatal.
    Experts say the average number of attacks in the country has increased in line with population growth and the popularity of water sports.
