Extinction appears very possible for many species of turtles worldwide unless actions are taken to save them.
From Science Daily:
Decimated by illegal hunting for both food and the pet trade along with habitat loss, many turtle species will go extinct in the next decade unless drastic conservation measures are taken, according to the report, which was released at a regional workshop hosted by Wildlife Reserves Singapore and WCS. Seventeen of the 25 species are found in Asia, three are from South America, three from Africa, one from Australia, and one from Central America and Mexico
....
"Turtles are being unsustainably hunted throughout Asia," said co-author Brian D. Horne of the Wildlife Conservation Society. "Every tortoise and turtle species in Asia is being impacted in some manner by the international trade in turtles and turtle products. In just one market in Dhaka, Bangladesh we saw close to 100,000 turtles being butchered for consumption during a religious holiday, and we know of at least three other such markets within the city."
Liz Bennett, Vice President of WCS Species Program, said: "Turtles are wonderfully adapted to defend themselves against predators by hiding in their shells, but this defense mechanism doesn't work against organized, large-scale human hunting efforts. The fact is that turtles are being vacuumed up from every nook and cranny in Asia and beyond."
While pet trade is often blamed, as this article shows, there are far more factors more damaging to native reptile populations.

The size of a flattened beach ball, the fossil of a giant frog, nicknamed "Frog from Hell" was discovered recently in Madagascar.
From BBC News:
The team from University College London (UCL) and Stony Brook University, New York, said the frog would have had a body length of about 40cm (16 inches), and was among the largest of its kind to be found.
"This frog, a relative of today's horned toads, would have been the size of a slightly squashed beach-ball, with short legs and a big mouth," explained co-author Susan Evans, from UCL's Department of Cell and Developmental Biology.
"If it shared the aggressive temperament and 'sit-and-wait' ambush tactics of [present-day] horned toads, it would have been a formidable predator on small animals.
"Its diet would most likely have consisted of insects and small vertebrates like lizards, but it's not impossible that Beelzebufo might even have munched on hatchling or juvenile dinosaurs."

Janaki Lenin had an idea of what she might encounter at the largest reptile show in the U.S., but as she points out, things are not always what you might think.
From The Hindu:
What would the National Reptile Breeders' Expo look like? I struggled hard to imagine what kind of people would buy and sell reptiles. May be ‘weird people' — pot-smoking, long-haired, and elaborately-tattooed dudes who drove Harley Davidsons. Rom, who had been to one several years ago, shook his head: “You've never seen anything like it.” And, he was right!
On an August Saturday balmy morning in 2005, as we walked past the long queue, waiting to get inside the convention centre in Daytona, Florida, I was amazed that ‘straight people' outnumbered the freaks. There were elderly people, young couples, teenagers, little kids. You'd think they were going to the supermarket!
Later in the article she discusses her second visit, and while she probably doesn't remember me, at the time I met both her and her husband, Rom.
By the end of the weekend, thanks to an enthusiastic group of associates, we had raised close to $ 25,000 for gharial conservation from the sale of t-shirts, books, items donated by individuals, zoos and organisations. The reptile fanciers' commitment for the gharial in far-off India was touching. I wondered if we could raise this kind of money for reptile conservation (do I hear an “ugh”?) here, in middle-class India. Sadly, not a chance.
Many of us donated; I know I gave them $20.00 at their booth. Why? Because at this point in my life I had not yet seen a real live gharial. Heck, I have given money to the IRCF Blue Iguana program and this summer was the first time I was with a 100 percent pure Grand Cayman Blue Iguana. To us, saving herps knows no country lines. From the Massasaugas in Illinois to the Gharials in India, I have donated so that they have the chance of living longer than me and that their beauty can inspire future generations of kids like me, who grew up thinking that snakes and lizards were wonderful and beautiful.

Scientist Samantha Joye recently released findings that contradict the BP spill compensation czar's report that states the Gulf will be completely cleared of all oil by 2012.
From Yahoo News:
At a science conference in Washington Saturday, marine scientist Samantha Joye of the University of Georgia aired early results of her December submarine dives around the BP spill site. She went to places she had visited in the summer and expected the oil and residue from oil-munching microbes would be gone by then. It wasn't.
"There's some sort of a bottleneck we have yet to identify for why this stuff doesn't seem to be degrading," Joye told the American Association for the Advancement of Science annual conference in Washington. Her research and those of her colleagues contrasts with other studies that show a more optimistic outlook about the health of the gulf, saying microbes did great work munching the oil.
"Magic microbes consumed maybe 10 percent of the total discharge, the rest of it we don't know," Joye said, later adding: "there's a lot of it out there."

"Crocs don't care if you are black, white, or purple, a tourist or a local, liberal or a truck driving red-neck. Swim in croc territory and you are bait." -Bryan Grieg Fry
With the post-cyclone flooding in Australia, crocs are on the move, and the number of croc attacks are on the rise. One would hope eventually folks would learn to stay away from areas where the salties live after a flood, but they haven't.
First up is a man being lauded a hero, although some of us still expect to see him up for a Darwin Award. Reading this from Daily Mail (and numerous other news agencies) made my head hurt:
Eddie Sigai, nicknamed 'Crocky Balboa' by his friends, punched and gouged the saltwater croc after the powerful animal grabbed hold of his hand.
The 37-year-old, from Weipa, Queensland, was swimming with his daughters Jennifer, 17, and Monica, 12, at a creek last week when the crocodile caught hold of his left hand and dragged him underwater.
Weipa is in Queensland, but still a distance from where the full impact of Yasi. Why a father would allow his children to swim in croc-infestedwaters is beyond me. But in true Aussie swagger, he earned a catchy nickname, "Crocky Balboa" and a tale to bore the pub with.
From ABC News, report of a wayward freshie ending up in someone's pool in Mt. Isa:
"We went and had a good look around the perimeter the following day and I really don't know how it got in," he said.
"Maybe it washed under somewhere in a fence line, but it's too hard to say whether it got in or whether it was put in.
"But I find it hard to believe it did manage to get in by itself."
A 14 year old boy is missing and presumed taken by a croc. From The Australian:
NT Police said they were told late this morning that the boy was playing with his brothers in a creek at Milingimbi in Arnhem Land when he was apparently seized by a crocodile.
Members of the Milingimbi community began searching the creek and surrounding area for the boy, but there had been no sign of him.
Members of the NT police territory response section were flying to the community from Darwin this afternoon to lead the search for the boy, police said in a statement.
Milingimbi is part of the Crocodile Island group off the coast of Arnhem Land, about 440km east of Darwin.
Last, a warning issued:
Chief Minister Paul Henderson is warning people not to play in swollen waterways because flooding has made it easy for saltwater crocodiles to move around.
"We're urging everybody to keep out of those waterways, keep out of those lagoons, keep out of those steams because crocodiles are on the move," he said. To read the full article, click here.

Count the Saltwater Crocs among those affected by Cyclone Yasi, which pummeled Queensland in early February.
First a report from the Billabong Sanctuary in Townsville:
Bob Flemming from the Billabong Sanctuary says his 12 breeding crocs would not surface for several days after the enormous category five cyclone crossed the coast at Mission Beach more than a week ago.
"They were traumatised for a couple of days," Mr Flemming told AAP.
"They stayed underwater for some time and didn't even surface for food."
But he said the crocs, some more than four metres long, have since recovered and are back to feeding again.
His wildlife park lost power but back-up generators kept incubators containing more than 300 crocodile eggs going
A report from last spring shows that after the floods, wild crocodiles are now on the cruise for a good meal.
The unusually heavy falls in the Burke shire, in Queensland's northwest, also brought a nasty surprise for locals in the form of 5m crocodiles.
"Because the floods bring the dead wildlife, the crocs follow them," said Jake Davis, manager of the Burketown Caravan Park.
"There's a big area of water, six or seven kilometres wide, and the crocs are just going where they like."
With the severe flooding this time around, we can only expect the same.

A recent report on the "Exotic Invasion" is claiming that despite the deep freeze of 2009, invasive species of all types still plentiful in Florida. However what is interesting to me is despite claims of the animals ability to migrate, officials are finding the animals in the same spots as before.
From the Miami Herald:
“Right now, the numbers aren’t all that different,” said park biologist Skip Snow. “We’re finding them in the same places we’ve been finding them.”
While scientists can only estimate the toll the Big Chill took on the army of exotic reptiles, fish and plants in the wilds of South Florida, field observations over the last year suggest nature knocked them down but not out. Some already are speeding down the road to recovery.
David Hallac, the park’s biological resources chief, said he expected a sharp decline in captured snakes. But last year’s total of 322 fell only about 10 percent from 2009.
One species that appears to have seen a sharp decline, and I will mention in my regular trips to Florida, the only wild invasive I have seen on a regular basis is the Green Iguana.
Once about as common as coconuts, green iguana have grown scarce all the way down to the Keys. At previously infested Bill Baggs Cape Florida State Park on Key Biscayne, the largest lizards — six-footers that might give a pit bull pause — have vanished.
But Elizabeth Golden, the park’s biologist, said she’s seeing small greens pop up. There also are plenty of black spiny tail iguanas in all sizes, another species that seems to have weathered the chill, she said, possibly protected by its underground burrows.
This gives a far different report than what we are getting from herpers.

Reptile-loving blogger David Manly tackles the subject of fear of snakes, venomous and otherwise.
From his blog on Scientific American:
Let's face it. Snakes are not most people's favorite animals. They slink and slither without making much noise, have a forked tongue with unblinking eyes, and fangs that bite or coils that wrap. Some snakes are so dangerous that people have died from the encounter.
According to a 2010 report by the World Health Organization, at least 20,000 people are killed by poisonous snakebites every year. Not surprisingly, snakes are commonly feared, disliked, and even hated.
And yet, snakes are some of my favorite animals, and I have been bitten more than my fair share. When I tell the stories of how I've been bitten, I always acknowledge that it was my fault, and that the snakes were acting solely out of instinct and self-preservation.
Yet he moves gracefully from the fear to something more important to medical science, and that is how venom can be used to save lives, with the help of kingsnake.com BFF Dr. Bryan Grieg Fry:
However, as venom continues to evolve, this creates areas Fry calls "hot spots," where venoms have evolved radically and could result in a decrease in the ability for antivenom to do its job. However, as dangerous as the situation can be, there is also opportunity.
These "hot spots" are where novel toxins will appear within venom, which can then be studied and analyzed for future use in drug design and development.
"Venoms have had a huge role in drug design and development such as Captropril, a high blood pressure medication developed from the study of the venom of Bothrops jararaca, [which] kill more people than any other in the region," said Fry.
Therefore, not only has antivenom saved countless people from pain, limb loss, and even death, but the study of venom has also helped develop various products that increase human health.
Not too bad for an animal long thought to symbolize evil.

A limestone fossil found in Lebanon holds clues to how snakes lost their legs.
From BBCNews:
The scientists' high-resolution 3D images suggest the legs in this particular species, Eupodophis descouensi, grew more slowly, or for a shorter period of time.
It is a conclusion made possible only after seeing all the bones obscured inside the limestone, and determining that although the creature possessed ankle bones, it actually had neither foot nor toe bones.
"This study reveals the degree of regression of the legs," said Dr Alexandra Houssaye from the Museum National d'Histoire Naturelle (MNHN) in Paris, France.
[....]
Two theories compete. One points to a land origin in which lizards started to burrow, and as they adapted to their subterranean existence, their legs were reduced and lost - first the fore-limbs and then the hind-limbs.
The second theory considers the origin to be in water, from marine reptiles.
This makes the few known bipedal snakes in the fossil record hugely significant, because they could hold the clues that settle this particular debate.

The Denver Zoo is celebrating the birth of tadpoles of the Lake Titicaca frogs in one of their major conservation partnerships.
From the Denverpost.com:
Denver Zoo staff assisted a breeding project at the Huachipa Zoo in Lima, Peru, in December and met with experts from around the world on strategies to preserve the giant frogs in the lake that straddles the border between Peru and Bolivia at 12,500 feet.
The Lake Titicaca frog is the Denver Zoo's top conservation project. Since 2007, the zoo has spent about $100,000 and advised local conservationists in the effort.
Although the five hatchlings did not survive, their births were considered a major step forward.
Denver has quite a long list of conservation projects beyond this one. To see an overview of their projects, click here.

Pennsylvania is home to one of the largest venomous reptile shows, but that may be history of proposed legislation to ban the sale of alligators and venomous snakes passes.
From WHPTV.com:
The question is, is there enough of a problem here that prompted this?
Apparently there is, in fact last year a man who runs a center to help exotic animals. Said this legislation needed to go through specifically about alligators he says he sees.
Senator Richard Alloway is expected to introduce a new bill that Jesse Rothacker says is long overdue. In Pennsylvania it's legal to buy pet alligators that start out tiny and end up huge.
The bill would amend Title 30 and make it illegal to buy or sell American alligators or venomous snakes.
We will keep an eye on the situation and let you know how it progresses. The video news clip can be seen after the bump.

When Krakatoa the Komodo dragon passed away this summer, my heart fell. I had the priveledge to get up close and personal to the amazing boy on a visit to the St. Augustine Alligator Farm. But questions still remained as to what would kill such a young, seemingly healthy animal.
Now, the St. Augustine Record reports:
Dr. Darryl Heard said Krakatoa was a young lizard when he died, which could have put him at risk for viral infections, as young animals have yet to develop immunity against the diseases. Heard is the primary veterinarian for the St. Augustine Alligator Farm and the zoological medicine service chief at the Department of Small Animal Clinical Science at the University of Florida.
Krakatoa had minor changes in his spinal cord, which could have been on-going damage from a viral disease, Heard said.
Other signs of neurological damage included some spinal cord lesions and also a weakness in the lizard's legs, leading Krakatoa to position his legs awkwardly, Heard said.
Steps are being taken to prevent illness in Tambora, the 3-year-old female originally planned to mate with Krakatoa.
Brueggen said the results from Krakatoa's necropsy are frustrating, mostly because it doesn't allow the doctors or specialist to focus on how to prevent a certain disease or virus from affecting Tambora.
Heard and Brueggen both said Tambora will be vaccinated for equine encephalitis and West Nile virus to prevent either disease from causing the lizard harm.
Krakatoa tested negative for both viruses, but both the doctor and Brueggen said it was a preventive measure.

It's hard to believe today marks 14 years since the birth of kingsnake.com.
In 1993, I was a hobbyist gray-banded kingsnake collector and breeder, working for a small computer networking company and learning about a new technology called "the internet." Designed initially as a way for researchers to share data sets, the internet was just becoming available, slowly, to the general public. I was looking for a way to learn more about the technology, and sociology, behind what was termed a fad by many, a whole new form of media by others.
Using Mark Miller's Philadelphia-based dial-up BBS Herp Net as inspiration, and with lots of help from gray-band friends, in 1994 I launched a web page for the small number of gray-banded kingsnake hobbyists online called "The Alterna Page" (pictured right). One of the first reptile-oriented web pages on the internet, it was designed to be a living and evolving compendium of knowledge on the gray-banded kingsnake. However it soon became the gathering spot for reptile and amphibian hobbyists of all interests, with its forums and classifieds providing the seed for what was to follow.
By the end of 1996, traffic on The Alterna Page had grown to the point that my hosting company demanded I purchase my own server and domain name. A $50 a month hosting account was no longer adequate, and my traffic was making their other clients' sites unavailable. It was at that point that hard decisions had to be made. Circumstance rather than design had turned my interesting hobby into a business, one in a new and untried medium, and given very little prospect of success by my family, co-workers, and most of my non-reptile friends.
It was after consulting with a few reptile friends like Joe Forks, John Cherry, Dave and Tracy Barker, and Ron Tremper -- as well as dozens of others -- that I borrowed some money for a server and signed the hosting contract.
On February 8, 1997 -- fourteen years ago today -- kingsnake.com was launched. The "powered by kingsnake.com" button (pictured right) is one of the original files from that web site, and it's still in use today on virtually every page on the site. (To see what kingsnake.com has looked like throughout the years, click on the link below.)
I want to thank the many users, advertisers, sponsors, volunteers, and staffers who have made kingsnake.com what it is today: the largest, most vibrant, and most popular reptile community on the internet.

The impact of the Deepwater Horizon Oil Spill was swift and hard and caused more deaths to the critically endangered sea turtles then any other cause in the past several decades.
A news report from mb.com.ph:
The report said the rate of dead, disabled and diseased sea turtles discovered in the months following the massive April 20 spill was four to six times above average. The analysis, by the National Wildlife Federation, the Sea Turtle Conservancy and the Florida Wildlife Federation, was conservative and only took into account turtles found on shore, not those rescued or recovered at sea.
Researchers with the federal government said it would take years to determine the full impact of the spill on sea turtles. Necropsies have been done on more than half of 600 turtle carcasses, and while some may have died from oil, most of the turtles drowned in fishing gear, said Monica Allen, a National Oceanic and Atmospheric Association spokeswoman.
Unseasonably cold temperatures last winter were also detrimental to sea turtles, most of which are considered endangered, said Gary Appelson, policy coordinator for the Sea Turtle Conservancy. "Sea turtles have had a tough year,'' Appelson said.

A recent study shows that while children may show a keen interest in things that cause fear in adults -- like snakes -- they do not by nature fear them.
From DiscoveryNews.com:
The study follows on the work co-author David H. Rakison of Carnegie Mellon University did with spiders and infants as well as research Susan Mineka of Northwestern University did with monkeys, which when raised in a lab show no fear snakes. When Mineka attempted to instill a fear of rabbits, flowers, and snakes in the monkeys they much more readily learned to fear the snakes.
Arne Ohman at the Karolinska Institute in Sweden showed that for humans, once a fear of snakes or spiders is established, when a photo of a snake or spider is shown the fear response will last longer than a fear response learned to something less immediately threatening such as a mushroom. The research suggests an evolutionary tendency for humans to have the ability to quickly learn to fear these creepy crawlies and then respond metabolically longer in that state of fear during an encounter.
I have done a ton of public education on reptiles and I always say girls until the age of 6 and boys after the age of 4 are in prime positions to learn to love, respect and understand a variety of animals. At 6, girls tend to start following society and after 4 boys tend to become more independent and are more open to new experiences. Most of the adults I talk with who have a fear will point to something that happened as a child that started the fear. We as humans are born without fear of snakes; perhaps that's one lesson we don't really need to learn.

We already know venom has properties that aid in blood pressure management, diabetes and pain relief, but can it also cure cancer? That is what a study team at the University of Northern Colorado is looking into.
“Ideally, we’d like to have something that will either minimize or eliminate cancer cell growth in the body,” said Mackessy.
They are focusing on three different types of cancer: melanoma, colon and breast cancer.
“One of the reasons for looking at those three is that they’re very, very common in humans here in the United States. It’s a critical health concern,” said Mackessy.

After a devastating summer for wildlife in Gulf Coast States, Alabama received a 1$ million grant to purchase coastal wetlands and create a preserve for the Diamondback Terrapin.
Smith said both tracts are waterfront property that have unique wetlands habitats.
"Both tracts need to be conserved, but one in particular, the one that we call the Heron Bay tract, happens to be the only stronghold of the last remnant habitat for the diamondback terrapin, which is a big deal," Smith said.
"There's a lot of interest in that habitat and some universities have been studying that area for years, and that's basically the last remaining habitat in the state of Alabama for the diamondback terrapin, so we're really excited that we’re getting this award to purchase that property."
Smith said the state Forever Wild program will provide $379,500 in matching funds to buy the property.
The diamondback terrapin is the only turtle in North America that spends its life in brackish water. About 40 to 60 of the turtles are believed to live in south Mobile County, according to a 2008 Press-Register story. The reptile is listed as a species of 'highest conservation concern' by the Alabama Department of Conservation and Natural Resources.
The purchase will also include areas called maritime forests, which are coastal woodlands. For the full article, click here.
