Spectacular fin whale breach a rare sight

Massive cetacean makes like a surface-to-air missile in Strait of Gibraltar; 'Rarely observed and even more rarely captured on camera'

Fin whales are the world’s second-largest whale species and can measure 80-plus feet and weigh as much as 70 tons. Because of their immense size, they rarely breach, which makes the photo accompanying this story all the more striking.
The image was captured May 22 in the Strait of Gibraltar from aboard a vessel operated by the Spanish conservation group CIRCÉ (Conservation, Information et Recherche sur les Cétacés).


CIRCÉ posted the image and video to its Facebook page last week. The video footage shows two of three breaches—the first at 3 seconds and the second at 1:15—and reveals a cetacean that is leaping almost completely free of the water. Fin whales, second in size only to blue whales, are incredibly sleek and can swim at bursts of up to 23 mph, which helps explain how this particular whale was able to make like a surface-to-air missile in the Strait of Gibraltar.
It’s unclear why the whale jumped, just as nobody is 100 percent certain why any of the smaller species of whales sometimes breach.
Humpback whales are famous for breaching, along with other surface behavior that could possibly represent a form of communication. Some scientists theorize that gray whales breach in an attempt to shake lice from their skin.
But fin whales, like blue whales, typically do not break the surface in a breaching behavior.
“It’s a very rare behavior,” said Alisa Schulman-Janiger, a California-based whale researcher. “It’s rarely observed and even more rarely captured on camera. If one does happen to breach, what are the chances that you’re going to be ready with a camera?”
Schulman-Janiger runs the ACS-L.A. Gray Whale Census and Behavior Project from the Palos Verdes Peninsula in Los Angeles County.
Fin whales, for the past several years, have been spotted feeding in nearshore waters off Southern California. In the project’s 31 years, volunteers have seen only a handful of fin whale breaches. That includes a phenomenal display last month, when one or possibly two fin whales breached 20-plus times.
The fin whale, named because of a prominent dorsal fin far back on its body, feeds predominantly on shrimp-like krill and schooling bait fish. The whales are found worldwide but are considered an endangered species, numbering about 40,000 in the Northern Hemisphere and 15,000 to 20,000 in the Southern Hemisphere.
The amazing photo of the Strait of Gibraltar breach inspired many comments on the CIRCÉ Facebook page, mostly in Spanish, but with some English-language commentary such as “Good grief. Imagine the splash!” and “Raw power… totally impressive.”
Another commenter asked, “Is this for real?,” and others also thought it might have been Photoshopped. Were it not for the supporting video footage, these would have been valid observations.

Five dead as Sierra Leone records first Ebola outbreak

Reuters

ABID (Reuters) - Five people have died in Sierra Leone's first confirmed outbreak of Ebola virus, the World Health Organisation (WHO) said on Monday, signalling a new expansion of the disease which regional officials said had been brought under control.
Ebola, a haemorrhagic fever with a fatality rate of up to 90 percent, is believed to have killed some 185 people in neighbouring Guinea and Liberia since March in the first deadly appearance of the disease in West Africa.
Previously, several suspected cases of Ebola were recorded in Sierra Leone early on in the West African outbreak, but they later tested negative for the disease.
In a statement posted on its website, the WHO said the outbreak in Sierra Leone was located in an area along the country's border with Guinea's Guéckédou prefecture, where some of the earliest cases of the disease were recorded.
"Preliminary information received from the field indicates that one laboratory-confirmed case and five community deaths have been reported from Koindu chiefdom," it said.
The WHO said it was deploying six experts to the area along with essential supplies.
The West African outbreak spread from a remote corner of Guinea to the capital, Conakry, and into Liberia, causing panic across a region struggling with weak healthcare systems and porous borders.
A total of 258 clinical cases have been recorded in Guinea since the outbreak was first identified as Ebola, including 174 deaths - 95 confirmed, 57 probable and 57 suspected - according to the WHO.
No new cases of Ebola have been detected since April 26 in Conakry, where an outbreak could pose the biggest threat of an epidemic due to the city's role as an international travel hub.
However Guinean health officials announced two new confirmed cases on Friday in an area previously untouched by the virus. [ID:nL6N0O94X8]
The disease is thought to have killed 11 people in Liberia.
Ebola is endemic to Democratic Republic of Congo, Gabon, Uganda and South Sudan, and scientists initially believed that Central Africa's Zaire strain of the disease was responsible for the infections in Guinea and Liberia.
However researchers later published a study saying the West African outbreak was caused by a new strain of Ebola. [ID:nL6N0N94AE]

Burger worker may have exposed thousands to hepatitis

As many as 5,000 people might have been exposed to hepatitis A at a Red Robin restaurant in Springfield, Missouri. The health threat is linked to an employee. VPC

SPRINGFIELD, Mo. — Health officials worry that as many as 5,000 people could have been exposed to hepatitis A at a Red Robin restaurant here after a worker was diagnosed with the virus.
Springfield-Greene County Health Department officials received a report Tuesday about the illness, which can affect the liver, and worked with state and federal officials to get enough vaccine shipped so people who went to the restaurant May 8 to 16 can be immunized.
The goal is to get as many customers vaccinated within 14 days of their possible exposure, officials said Wednesday. Otherwise, the shot won't work, so they've set up clinics through the Memorial Day holiday weekend.
"Upon being informed of the incident, the Springfield Red Robin took all safety measures to ensure the well being of our guests and team members including arranging the inoculation of all Springfield team members with the immune globulin prophylaxis shot," Red Robin Gourmet Burgers (RRGB) officials said in a statement.
The restaurant now is considered safe, health department officials said. The city of Springfield, in southwest Missouri, has about 160,000 residents.
STORY: Teavana worker may have exposed shoppers to hepatitis
STORY: 118 sickened in hepatitis A outbreak linked to berries
Typically, hepatitis A is spread from the feces of an infected person to some food or drink that another person consumes. That's why proper hand washing after using the bathroom offers the first line of defense.
Hepatitis A does not always produce symptoms, and adults are more likely to have symptoms than children. Symptoms include nausea, vomiting, fever and yellowing of the skin or eyes.
Most cases of hepatitis A infection resolve themselves in a few weeks and do not cause permanent liver damage. About 10% to 15% of those who have the virus have a relapse of symptoms at some point in the six months following its onset, according to the federal Centers for Disease Control and Prevention.
Since the early 1990s the number of acute hepatitis A cases nationwide has fallen dramatically from more than 30,000 in the early 1990s to fewer than 1,700, attributed in great part to the introduction of the hepatitis A vaccine.
Nationwide, the CDC estimates that about 2,700 people came down with acute cases of the disease in 2011; about 1,400 cases were reported, an average of 28 cases per state.
Also recently:
• A Red Robin employee in Stroudsburg, Pa., also was diagnosed May 5 with hepatitis A. The Pennsylvania Department of Health did not consider the diagnosis a risk to the public though officials did say customers who dined there April 16 to May 5 should contact the department with concerns.
• A Teavana worker in Indianapolis may have exposed shoppers to the virus on three occasions in April while preparing tea samples, said Marion County Public Health Department officials, who told customers to watch for symptoms and offered vaccines for those who had been more recently exposed. Teavana is owned by Starbucks (SBUX).
• A Papa John's (PZZA) employee in Charlotte, N.C., may have infected customers of the pizza shop March 27 to April 7, according to the Mecklenburg County Health Department, which had more than 700 people come to vaccination clinics not far from the restaurant.
