Ploughshare Tortoises have been coveted for decades, their ownership often connected with direct smuggling, but The Turtle Conservancy in Ventura, CA has recently acquired eight new additions and hopes to breed them.
But Saturday's VIPs were eight ploughshare tortoises flown in from Hong Kong in padded crates. Among them is a female of breeding age, which Eric Goode and his associates at the nonprofit Turtle Conservancy's Behler Chelonian Center hope to mate with the only male ploughshare tortoise of breeding age in North America.
"That male, which is en route from a zoo in Texas, hasn't seen a female ploughshare tortoise of breeding age in more than 25 years," Goode said as he marveled at the new arrivals in a quarantined pen. "We're hoping for the best. These creatures have seen nothing but bad luck, corruption and greed in captivity."
Some would call that an understatement. With fewer than 300 left in the wilds of Madagascar, the ploughshare tortoise holds the dubious distinction of being the rarest tortoise on Earth. They are heavily targeted by global animal traffickers, and the high-domed creatures fetch tens of thousands of dollars on the Asian black market, conservationists say.
Until recently, attempts to breed the ploughshare tortoise outside of Madagascar failed miserably. In the early 1980s, a male died shortly after zoo workers in Honolulu used an electric device to procure semen from the animal. A female that it was supposed to have mated with had her ovaries removed during a botched operation.

My favorite part of being a reptile owner is educational programs with children. Opening their eyes to the natural world around them helps open up children to a myriad of possibilities for their future. Good to see that in India, that feeling is the same.
From The Hindu:
After the tour, the kids enjoyed a “Show and Tell” session with the education officers. A baby Caymen croc, a baby Indian Rock Python and a baby Black Pond Turtle were displayed and the children were able to observe at close quarters what they would have missed if they saw them from afar. Their characteristics and parts of their body were explained — they got to see the webbed feet of the turtles and examine it closely and learnt the importance of having it. The sinewy muscles of the baby python was exclaimed over — for they now understood how it could coil and twine around things with such strength and move. They noticed the third eye of the baby croc, which closes under water.
[....]
Getting back to the Croc Bank, after a little rest the kids got down to setting up a fresh water aquarium for the turtles. They checked the water levels and kept little pots and vegetation for the turtles to nibble and hide under. They also put in tiny fish. It was now time for some painting, which actually was to create an artificial butterfly garden. The concept was to paint the flower have a vial of honey inserted in the centre so that butterflies would get attracted to it. Play time in the beach was followed by the finale — where certificates and prizes wee distributed with a special Croc Bank Kit.
It was an unique experience for these kids, an experience which made them understand and appreciate the natural world and also the importance of conserving it with everything they've got.
To open the eye of children, especially where there are so many native dangerous reptiles is a wonderful thing.

It may take decades to realize the full impact the oil spills in the Gulf will have on wildlife, but researchers are increasing monitoring of sea turtles during this important nesting season.
From The Associated Press:
While scientists in several states are studying the effects of the oil spill on loggerhead and other sea turtles, the Kemps ridley have been of particular concern. The Deepwater Horizon explosion on April 20, 2010 happened when they typically would have been in the area. Most of the 456 visibly oiled turtles rescued by the U.S. Fish and Wildlife Service last year were Kemps ridleys.
At the peak of nesting season, their numbers looked good. As of May 24, 155 Kemps ridley nests had been spotted on Texas shores — more than in all of last year and more than had been counted by that day in 2009 and 2008. The same is true for some other sea turtle species, although they have just started to nest so it might be too early to have confidence in those numbers.
And because sea turtles don't reach reproductive age for at least a decade, the full effects of the oil spill might not be known for years.
"There is fear that some of the turtles that took the year off from nesting or after the turtles were done nesting during the 2010 year, that they entered the waters where the oil had been present," said Shaver, explaining that the reptiles often forage off the hard-hit Louisiana, Alabama and Mississippi coasts before or after nesting along the Texas Gulf Coast.
"There is concern that perhaps those turtles have been impacted from the oil and could then have problems with their reproduction," she added.

Southland Museum and Art Gallery tuatara curator Lindsay Hazley started out 27 years ago with two animals. She now has a colony of 80 captive bred Tuataras with no where to go.
From Otago Daily Times:
The museum's tuatara surplus is the result of Mr Hazley overcoming many captive-breeding problems and he is getting 20-30 fertile eggs each year.
"With the new acrylic roof I got from Germany that let's all the UV (ultra-violet light) through, I'm getting a 90% survival rate rather than a 90% failure.
"I'm sending eggs to Victoria University from now on because I'm saturated."
Mr Hazley would like to liberate some of his animals on a tiny pest-free island in Foveaux Strait.
"It would be just [big] enough to put a few animals on to see how they are going to do."
Mr Hazley said he had been talking to interested parties about the possibility for 20 years but there had been little progress.
He believed it was not the museum's job to make the project happen.
"It's more of a Doc or iwi thing. Somebody else needs to drive it. I can breed the animals for it but no-one's out there wanting to drive it."
This is an amazing chance at recovery for a species that needs the help badly. To read the full article, click here.

Those who have the chance to watch an Arribada, the mass laying of eggs by numerous female sea turtles, describe it as one of the most amazing experiences anyone could have. But as the turtles become more endangered, that sight is getting hard to find.
From The Hindu, one person's experience:
She was sweet 17, profoundly pregnant; and yet floated effortlessly, adrift in the warm waters off the east coast of India. The Olive Ridley sea turtle was waiting for darkness to envelope her. She was pregnant for the first time and would breed many more times in her life span of 100 years. Stealth was not her intention as she waited 700 yards from the sandy beach at the mouth of the Rushikulya in Orissa. A few yards away, another female turtle joined her, then a third, followed by a dozen, then hundreds and thousands. They gathered as if for a colossal hen party, instinctively following an uncanny ritual that happens in the dead of the night.
All the expectant mother turtles slowly crawl towards the virgin beach. “Look, there comes the first fat lady,” said turtle researcher Sajan John, holding a tiny torch, as I peered into the darkness. I was witness to an Arribada, which means “Arrival” in Spanish. Arribada is the astounding nesting inclination of the Olive Ridley turtle. Large groups of turtles gather off the seashore and, in a short span of a few nights, they invade the beaches in regular intervals to lay eggs in collective clutches. The nesting density is so high that previously laid eggs are unwittingly dug up by other turtles to lay their own eggs! Each clutch has at least 70-100 ping-pong sized white eggs stacked in a tubular pit excavated in the soft sand.

Reports on the internet surfaced late yesterday that legendary reptile keeper and inspiration to reptile hobbyists world wide, Bill Haast, founder of the Miami Serpentarium, has passed away. We are still trying to confirm this information as it has yet to appear in the main stream press and will keep you updated as more information becomes available.
If any man deserved the sobriquet "legendary" in this community, Bill Haast led the way. I only met Bill in the later years of his life but knew of and read of his exploits in the field and in the lab for many years prior and many of his proteges at times took me under their wing, feeding me stories of their time growing up at or around the Serpentarium in the 60s and 70s.
I am far from right the person to be writing Bill's obituary so I have asked several of his friends and disciples to step up in my place and their remembrances will be posted later today and tomorrow. I am sure many of our readers have interacted with Bill over the years and I invite them to share their memories here.

While all other amphibians wither and are unable to survive in salt water environments, crab-eating frogs (Fejervarya cancrivora) in Indonesia have evolved to survive and thrive in it.
From Biodiversity Science:
Thin permeable skin is both the cornerstone and the millstone of amphibian evolution. On the one hand skin provides a useful site for gas exchange; on the other, free water movement across skin confines amphibians to freshwater. Indeed, of the 6,500 recognised amphibians, only the crab-eating frog can enter the sea.
Unlike other amphibians, which rapidly dehydrate in seawater, crab-eating frogs absorb urea across their urinary bladder in order to eliminate the osmotic gap between body fluids and seawater. Seawater acclimation requires several days, leaving the frogs with two equally disagreeable options — they can take up salt and lose water to the sea, or face desiccation on land.
This gave scientists the option to to study very unique amphibian. To read the rest of the article, click here.

For an endangered species of frog, the regurgitation of 10 babies is exciting news. Add to it that the male is handling the initial rearing, and ow the story gets even more interesting.
From MSNBC.com:
The vulnerable species is one of two members of the only genus on Earth that rears its young inside of its vocal sac, a job taken on by the males.
"They have a small opening below their tongue. … After [the eggs] hatch, he takes the tadpoles into his mouth and manipulates them through that opening and into his vocal sac," Danté Fenolio, a conservation scientist with the Atlanta Botanical Garden, explained to me today.
"For about 60 days, they go all the way through to development inside his vocal sac. At that point when they are ready, fully developed, he coughs up fully formed miniatures of the adult."
Fenolio is working on a captive breeding project with the National Zoo and Universidad Catolica in Santiago to build a so-called assurance population of the frogs that can be released into the wild once, or if, environmental threats to their natural habitat are thwarted.
These frogs are being captive bred and working toward an assurance colony. But as Fenolio points out, assurance colonies just buy time, not save the species.

The devastation caused by Chytridiomycosis in amphibian species is well known, but recently a link was found between the strength of the disease and pristine environments.
From Mongabay.com:
Examining tropical frog populations in Costa Rica, Australia, and Brazil's Atlantic Forest, the researchers found "that paradoxically, habitat loss is negatively associated with occurrence, prevalence, and infection intensity of [chytridiomycosis] in amphibian populations in the tropics." The finding goes against research of other animal diseases, which usually find that risk of disease increases in disturbed habitats.
In this case the researchers suspect that either the lethal disease depends on the ecosystem having an undisturbed microclimate, or that a decline in amphibian diversity and abundance—due to habitat loss—slows the spread of the disease.
The finding also explains why the presence of chytridiomycosis is often seen in higher altitudes where forest is less disturbed.

A recent study at the University of Massachusetts compares snake venom to -- of all things -- catsup.
The study actually focused on delivery methods, because the minority of venomous snakes have hollow, hypodermic needle-like fangs. From Discovery News:
The interaction of the fangs and flesh of the bitten animal form a channel along which the venom flows. The flesh acts like blotter paper to wick the venom in. The suction created by the blotting effect helps the venom keep flowing. The wicking of venom into flesh also means that the snake doesn't need to expend energy to pump the venom in.
J. Leo von Hemmen, a biophysicist at the Technical University of Munich, Germany and Bruce Young, a biologist at the University of Massachusetts in Lowell, started their research after noticing that only a seventh of venomous snakes, such as rattlesnakes, have hypodermic needle-like fangs.
Many venomous snakes and lizards have much simpler set-ups, often only grooves in the fangs, and yet are effective hunters. The fangs of the mangrove snake and banded snake were both examined by the researchers to understand how venom flows.
The physical properties of the venom itself allow venom to get past even bird feathers, which usually deflect liquid. Snakes that regularly eat birds were found to have deeper channels in their fangs, which increased the ability of the venom to evade feathers.
Something to ponder at your next summer barbecue. After the bump, a video showing the hemotoxic changes of venom to meat.

The tragic death of a volunteer in Grand Cayman has left the conservation community shattered.
Daniel Hamilton, a student at Purdue University, was passionate about reptiles, conservation, and the effort to restore the Blue Iguana in Grand Cayman. His life was cut short on Friday, June 3, 2011, while in Grand Cayman volunteering for the Blue Iguana Recovery Programme.
Our hearts are heavy at kingsnake.com today and our thoughts are with the Hamilton family and Daniel's friends, fellow students, and colleagues at the Programme. In lieu of flowers, the family has asked for donations to the Blue Iguana Recovery Programme here.
His hometown paper, The Exponent wrote:
Rod Williams, an associate professor of wildlife science, helped Hamilton share his love for reptiles through one of Williams' classes called nature of service learning. Hamilton was able to go to a local elementary school and present to children a lesson on wildlife and the environment.
"In my interactions with Daniel, he had two passions. He had a passion for herpetology (study of reptiles and amphibians) and a passion for teaching people about natural resources and the environment, especially if it involved amphibians and reptiles," Williams said.
Hamilton's brother and a Purdue alumnus, John Hamilton, said his brother, even from a young age, would indulge in his love for animals, especially reptiles.
"I don't remember a time when he didn’t like dinosaurs or reptiles," John said. "He always had a way with them, it was nice to see someone so in tune with those creatures."
[...]
"He was a very fair and genuine person,” John said. “He lived life honestly."
His exuberance for life made an impression on a family friend and roommate, Christina Morse, a recent graduate from the College of Liberal Arts. She said Hamilton was always positive and he made sure a situation never got boring by cracking jokes.
"He was very much about making jokes and making people laugh,” Morse said. “He always wanted the best for people."
Hamilton died around the creatures he loved the most. Morse said he was doing what he truly loved and believed in.
"He was one of the few students that went to Purdue to do something he absolutely loved instead of doing something to get a job one day," Morse said.
From the official press release from the International Reptile Conservation Foundation and the Blue Iguana Recovery Programme:
As reported by authorities recently in local media, a young international volunteer with the Blue Iguana Recovery Programme passed away suddenly last Friday, 3rd June.
Daniel Hamilton was 21 years old. He was pursuing a Bachelor of Science Degree in Wildlife at Purdue University, Indiana. He spoke of a lifelong fascination with reptiles, and how when first saw Blue Iguanas at an exhibit in the Shedd Aquarium in Chicago, he knew he wanted to play some part in their rescue.
Daniel’s volunteer application was outstanding – he had done fieldwork with salamanders in state forests in Indiana, had learned techniques like radio tracking, tagging and navigation, and his enthusiasm sparkled in his communications as he prepared to come to Grand Cayman.
In his short time with us, Daniel launched himself wholeheartedly into the work of the Programme, first at the captive breeding facility in the QE II Botanic Park, then in the Salina Reserve inland from the Queen’s Highway, and finally in the new Reserve in Colliers, East End. There, he and two other international volunteers were preparing for this year’s release of Blue Iguanas, scheduled to take place in July.
The staff and current volunteers with the Blue Iguana Recovery Programme, and the Council and staff of the National Trust for the Cayman Islands are deeply shocked and saddened by Daniel’s unexpected passing, and extend their heart-felt sympathy and condolences to his family and friends. Thanks and recognition are also extended to the emergency services who did everything possible to save Daniel.
The community’s expressions of sympathy are sincerely appreciated. We invite anyone who wishes to send condolences to email birpvols@gmail.com or post on the Blue Iguana Recovery Program’s Facebook page https://www.facebook.com/pages/Blue-Iguana-Recovery-Programme/183865225017 , and the BIRP will arrange for these thoughts to reach Daniel’s family
More about Daniel after the jump.

As the reptile community battles to prevent the federal government from adding nine new species of constrictor snakes to the Lacey Act, AOL News breaks with a story supporting out efforts.
The pending regulations would result in the loss of thousands of jobs and endanger an estimated $1.4 billion in national and international trade of captive-bred snakes, according to the United States Association of Reptile Keepers.
Calling the proposed rule "the wrong action," the group said in a statement last week that, if enacted, the law would have "no significant effect on the solution of current or future problems posed by the constrictor snakes."
The U.S. is largest producer of captive-bred reptiles worldwide, responsible for 80 percent of global trade, Andrew Wyatt, president and CEO of USARK told AOL Jobs in an interview.
[....]
The Fish and Wildlife Service estimates that $3.6 million to $10.7 million will be lost from retail sales of such snakes by companies or individuals, although some reports have put the loss as high as $1.8 billion.
The economic impact extends well beyond the obvious pet-related businesses, which is why there is such variation in the numbers. To check out the full article, click here.
Geneticists have been trying to create any new species of anything for many years, and have finally succeeded with the Whiptail Lizard.
From Physorg.com:
Scientists have known for years that some species exist due to interspecies mating, the whiptail lizards have provided proof of that; they’ve been creating new species themselves for at least several hundred thousand years. What’s new is the process being manipulated by another species, us, Homo sapiens. Geneticists have been trying for years to create a new breed of pretty much anything by urging lab “volunteers” of differing species to mate with one another, not exactly earth shaking science when you consider a dog that tries to mate with a human leg. Efforts such as these are, not surprisingly, more often successful than not; the problem is, the offspring are usually infertile, such as mules, or too weak to survive. The trick has been to create a new species that is able to both survive and reproduce, because otherwise, it can’t really be called a new species if it only exists for the duration of one generation.
In a paper published in PNAS, lead researcher Peter Baumann of the Stowers Institute for Medical Research, describes how he and his team paired an A.inornata male with an A.exsanguis female resulting in six eggs; all of which hatched, resulting in young lizards that were more similar to the female than the male, save a bit of blue tint on the tails. Each also had four copies of their parental genes (normally there’s just two), three from their mother, the other from their father. They were also all female and all able to reproduce by cloning themselves.
Not only have the initial lizards survived and reproduced, so too have their offspring; the lizards are currently in their fourth generation, leading to the inevitable question of whether they should be given a name. Baumann is hesitant to do so as it’s likely to court controversy from the biology/genetics community as the new species hasn’t yet been given the opportunity to show that it can exist outside of a lab, though the team members certainly believe it’s capable of doing so.
I have mixed feelings about this, both the cloning and the full elevation of species. To read the full article and decide for yourself, click here.

Ever wonder what those herps think when you pick them up in the wild? So does my favorite columnist at The Hindu.
I woke with a rude shock and was petrified by what was happening around me. My whole world was rushing by so fast that I hung on with all the stickiness that my toes allowed. My eyes just saw a blur and it was so disconcerting that I shut them tight.
The air stank, particles of black muck settled on me clogging the pores of my skin, it became so hot that my toes were on the verge of frying, and my eardrums just couldn't handle the noise.
Finally, when the world came to a standstill, I was so numb that I very nearly fell down from dizziness. I was just gathering my wits when she yelled: “Hey Rom, there's a tree frog here. What to do?” The man called Rom answered: “Just put him over there by the bushes.” She was mortified: “Here! At the mechanic's? He'll die.” Rom tried to reassure her: “No, no. He'll be fine.” Was he nuts? How could I survive in this hot tinderbox of a concrete jungle? She hissed: “Give me that plastic bag.” “What are you going to do?”
Just as I was about to make good my escape from their evil clutches, she caught me with the bag. She sprinkled some water from her bottle, threw some green leaves and knotted it tight. She bit a small hole in the bag and tucked me into her knapsack. That was how I came to be frognapped!

Scientists think a study of tree frogs can help us understand the mysteries of the tropics, and the vast number of species that reside there.
From Science Daily:
"Treefrogs are a particularly important group to study for understanding amphibian diversity, because they can make up nearly half of all amphibian species in some rainforest sites," says lead author John J. Wiens, an Associate Professor in the Department of Ecology and Evolution at Stony Brook University. "Treefrogs also offer a striking example of the high local-scale biodiversity in the Amazon. At some sites in the Amazon rainforest, there are more treefrog species in a small area than there are across all of North America or Europe."
The researchers compiled data on the number of treefrog species at 123 sites around the world and analyzed the data with a new evolutionary tree (based on DNA sequence data) for 360 treefrog species. They discovered that the richness of treefrog species in the Amazon rainforest sites is not explained by wet, tropical climatic conditions alone.
"In fact, we found that many tropical rainforest sites that are outside the Amazon Basin have no more species than do some sites in temperate North America," explains Dr. Wiens.

Along with people, many animals were displaced in the recent tsunamis that ripped through Asia. The unlikely duo of Mzee the Aldabra tortoise and Owen the baby hippo were among the survivors.
From NPR:
Just before Christmas the unseasonably heavy rains near Malindi town washed a family of hippopotamuses down the Sabaki River and out to sea. The residents of the town tried in vain to urge the family back up the estuary. When the Tsunami hit Malindi, the sea turned angry, the sky clouded over and for a moment the hippos disappeared and were forgotten as all efforts went to rescuing the stranded fishermen.
The next day only one hippo could be seen. It was the baby and he was stranded on the reef. Hundreds of people came to watch the efforts to rescue the hippo. It took ropes, boats, nets and cars —though the hippo was tired he was still fast and slippery. It took a brave rugby tackle to finally capture him, and the cheering of the crowd could be heard over a kilometer away.
Lafarge Eco Systems agreed to provide a home for the baby hippo and I rushed to Malindi to collect him. Tangled in fishing ropes, angry and tired, the hippo did not seem to appreciate our rescue at all. As we left for Mombasa, the crowd unanimously agreed to name him 'Owen' in honor of the volunteer who tackled him to the ground.
Exhausted, confused and extremely frightened, Owen immediately ran to the safety of a giant tortoise when we released him in Haller Park. Mzee, our 130 year old tortoise, just happened to be nearby and he was very surprised by Owen's odd behavior cowering behind him as a baby hippo does to its mother. Mzee quickly came to terms with his new friend and even returned signs of affection. The unusual relationship between this baby hippo and the ancient tortoise amazed people the world over and has featured in most countries on television and in news papers.
There is also a lovely photo journal and very detailed account of this story here.
