An experiment has shown green sea turtle embryos are much more likely to die when they are inside eggs that go underwater for six hours.

Scientists say the study shows the turtles, which rely on low-lying coastal habitats, are likely to feel the early impacts of rising sea levels.

"In some places it only takes a small rise in sea levels, when combined with a storm or a king tide, to inundate what had previously been secure nesting sites," said lead researcher Dr David Pike of James Cook University.

Scientists have welcomed the first results of a captive breeding program aimed at saving a group of critically endangered Fijian crested iguanas, the first such attempt to reintroduce a species in that country.

Some of the iguanas that were introduced to the Fijian island of Monuriki two months ago have been tracked down by scientists and appear to be healthy.

A total of 32 iguanas were microchipped and released, with tiny radio transmitters glued to the tails of 11 for tracking purposes. Nine were recovered on Sunday.

US Geological Survey biologist Robert Fisher reported all had increased in length and lost their excessive weight. A lean diet of native plants had evidently “sorted them out,” he said. There was no evidence of trauma or other health issues.

The bulk of his hospital bill — $83,000 of it — is due to pharmacy charges. Specifically, charges for the antivenin used to treat the bite. KGTV reports that Fassler depleted the antivenin supplies at two local hospitals during his five-day visit. Nobody expects antivenin to be cheap. But $83,000?

There's currently only one commercially available antivenin for treating venomous snakebites in the United States -- CroFab, manufactured by U.K.-based BTG plc. And with a stable market of 7,000 to 8,000 snakebite victims per year and no competitors, business is pretty good. BTG's latest annual report shows CroFab sales topped out at close to 63 million British pounds, or $98 million dollars, last fiscal year. The antivenin costs hospitals roughly $2,300 per vial, according to Bloomberg, with a typical dose requiring four to six vials. In some cases multiple doses are needed, according to CroFab's promotional Web site.

BTG has fought aggressively to keep competitors off the market. A competing product, Anavip, just received FDA approval this year and likely won't be on the market until late 2018. This lack of competition is one reason that snakebite treatments rack up such huge hospital bills -- $55,000. $89,000. $143,000. In May of this year, a snakebit Missouri man died after refusing to seek medical care, saying he couldn't afford the bill.

The roughly 120 million-year-old snake, dubbed Tetrapodophis amplectus (literally, four-legged snake), likely didn't use its feet for walking. Instead, the appendages may have helped Tetrapodophis hold onto a partner while mating, or even grip unruly prey, said study co-researcher David Martill, a professor of paleobiology at the University of Portsmouth in the United Kingdom.

Previous research has detailed two-legged snake fossils, but this is the first known snake ancestor to sport four legs, he said. It likely evolved from terrestrial-burrowing creatures, and was a transitional animal that lived during the shift from ancient lizards to modern-day snakes, he added.

Two months ago the world’s conservationists crossed their collective fingers and waited to find out if a 100-year-old female Yangtze giant softshell turtle (Rafetus swinhoei), the last of her gender, would—after artificial insemination—finally lay fertile eggs and save her species from extinction.

I’m sorry to say that those hopes have, at least temporarily, been dashed. The Turtle Survival Alliance reported this week that the centenarian did lay 89 eggs, but all were infertile.

That doesn’t mean the quest is over, however. The female is expected to lay one or two more clutches of eggs this year. They’ll try to inseminate here again before then.

Officers from the Florida Fish and Wildlife Conservation Commission visited the home of William Henry Jowett after receiving a tip that he was keeping two of the threatened reptile at home.

The 53-year old eventually received a misdemeanor citation after he was discovered keeping two loggerhead sea turtle hatchling. The penalties for this included up to one year imprisonment and a potential fine of up to $1,000.

Jowett reportedly obtained the animals from the canal in his backyard two months ago and decided to place these in a saltwater aquarium to show to his daughter. He said that he had plans to release the turtles but became attached to the animals.

The animals were taken from the aquarium and moved to the Loggerhead Marine Life Sanctuary Center. The turtles were later released offshore.

Crypsis is an entity’s ability to avoid detection. It can be a predator’s ability to avoid being spotted by prey, or prey’s ability to avoid being spotted by predators, or, in this case, an animal’s ability to avoid being spotted by biologists. Although I know it’s a valid term for a behavior, I can’t help but admire the ability of biologists to make their own failure to find an animal into a recognized property of the animal.

A Vietnam veteran was shot while trying to save baby sea turtles at a South Florida beach.

Stan Pannaman, 72, of Tamarac, was shot Friday night near a sea turtle nest in Lauderdale-by-the-Sea.

Pannaman said he and Doug Young, a fellow volunteer trying to protect the nest, were confronted by Michael McAuliffe, who approached them and said he didn't like sea turtles.

"He got more aggressive and he got up and he came towards us and he started pulling the stakes away from the nest area," Young told Local 10 News.

Reptile conservationist Gary Powell said: "If tins are disturbed outside of an official survey then it can affect the results of the research".

Disturbing protected species could result in breaking the Conservation of Habitats and Species Regulations Act.

Conservationists from Amphibian and Reptile Conservation and Dorset Wildlife Trust leave small pieces of tin and sometimes roofing felt at Upton Heath nature reserve in Corfe Mullen.
