While dogs are America's most desired pet, and 21 percent of people rated snakes as the most terrifying of all animals, a hefty 18 percent say they want... a pet dinosaur.
From National Geographic:
Public Policy Polling interviewed 603 registered voters by telephone between June 11 and 13, asking them 36 questions relating to their views on pets, animal phobias, and other random creature preferences. The poll, which was not authorized or paid for by any campaign or political organization, had a margin of error of +/-4 percent.
[...]
1. Twenty-one percent rated snakes as the most terrifying animal, followed by alligators at 19 percent and sharks and bears at 18 and 14 percent, respectively.
2. Nine percent of those polled are vegan or vegetarian, while 91 percent are not.
3. Eighteen percent believe the Loch Ness Monster is real.
4. On preferences for an exotic pet, 26 percent said they would choose a tiger, 20 percent a giraffe, 18 percent a dinosaur, and 16 percent an elephant. (Read about exotic animals as pets.)
5. Ninety percent said they would not want a hippopotamus for Christmas—perhaps to the collective relief of hippos worldwide.

A German snake expert lost his life after being bitten by a viper during an educationl presentation in France.
From Time:
Dieter Zorn, 53, was in the middle of a presentation about reptiles when he was bitten several times by an Aspic viper. Due to a rare allergy, he suffered a heart attack and died shortly thereafter.
Zorn had been travelling to different villages across the region, delivering presentations that focused on educating the public about snakes and reptiles and helping them overcome their fears of the creatures. After he got bitten, he managed to get the snake back into a cage, preventing it from attacking anyone else present, the Local notes.
Emergency responders arrived at the scene and attempted to administer a blood thinner, but they weren’t able to save him.

There's a new organization in the science world, the Ugly Animal Preservation Society (UAPS), "dedicated to raising the profile of some of Mother Nature's more aesthetically challenged children." The organization's president, Simon Watt, is fed up with pandas getting all the attention.
From Discovery News:
Watt, who is also an evolutionary biologist, and his team definitely did not showcase cute and furry pandas at recent UAPS events held at the Edinburgh Science Fest and Bristol's Big Green Week. Media attention instead was paid to animals such as the appropriately named blobfish.
"Our society needs a mascot, one to rival the cute and cuddly emblems of many charities and organizations," shares Watt.
At the end of each UAPS event, the audience votes on a mascot.
One contender is the Chinese giant salamander, with a head resembling an angry block of concrete.

Environmental contamination is causing some alligator populations to have difficulty reproducing.
From Living Alongside Wildlife:
When the sizes of penises were compared between lakes, alligators in Lake Apopka had on average 24% smaller penises than alligators in Lake Woodruff. When the time came for these juveniles to reproduce, this significant reduction in penis size made it difficult to mate and certainly didn’t impress the lady alligators.
This study showed that male alligators in Lake Apopka, which is contaminated with endocrine disruptors, were significantly different than alligators from a lake that had relatively little pollution. In order to help determine the physiological drivers, in other words the chemical pathways in the body that shape these physical differences, behind this reduction in penis size, Dr. Guillette also looked at plasma testosterone concentrations. Plasma testosterone is responsible for the formation and development of male external genitalia. He discovered that juvenile alligators in Lake Apopka had 70% lower concentrations of plasma testosterone than those at Lake Woodruff. Abnormal hormone levels like these are associated with decreased sperm counts and reduced fertility. This can be disastrous for maintaining healthy wildlife populations. The results of this study inspired Dr. Guillette to continue to look at the physiological effects of endocrine disruptors on reproductive systems.

Someone thought Mother Nature could be improved on with nail polish and glitter when it came to the shell of an Eastern Box Turtle -- putting the turtle's life at risk.
From care2.com:
Earlier this week, the good folks at the Wildlife Center of Virginia rescued an Eastern box turtle discovered at a nearby campground after it fell victim to an unscrupulous ‘artist’. According to staff, the reptile’s shell had been vandalized with several types of nail polish and glitter — threatening its survival by making it an easy target for predators.
“Box turtles have this great natural camouflage that just allows them to blend into their environment,” says staffer Amanda Nicholson. “And this is really sending a message to the world of, ‘hey, look at me.’”
The wildlife center isn’t certain whether the turtle is an abandoned pet, or if someone ran across it in the wild and decided to add this gaudy graffiti, but the tagged shell does offer some clues as to who might be responsible. Along with the word “Sheldon”, taken to be the female turtle’s name, are the initials “SKR” and “BDM” — perhaps belonging to the culprits.

University of Texas at Arlington evolutionary biologists Todd Castoe and Matthew Fujita are part of the team unlocking secrets of the Western painted turtle genome to find ways to help humans.
From the Star-Telegram:
Castoe and Fujita were among nearly 60 co-authors of a paper published in the journal Genome Biology this spring that described the findings from the genome sequencing, only the second full genetic mapping on a reptile.
The researchers found that the painted turtle’s genes used for tolerance of extreme cold and oxygen deprivation are common to all vertebrates but that they are more active in turtles that experience the extreme conditions. One gene that humans share became 130 times more active in turtles subjected to low-oxygen environments.
Further study of the turtle genome could yield clues related to human health and well-being, particularly oxygen deprivation, hypothermia and longevity.
“It’s very hard to do research on people,” said Pamela Jansma, dean of the UTA College of Science, “but if you know that animals have a similar gene pairing, you can study how those genes trigger responses to environmental stimuli. You can map that to humans, and you can then imagine developing gene therapies to address certain diseases.”

Frogs bearing Charles Darwin's name are at risk of extinction in Chile.
From Live Science:
Charles Darwin first discovered the frogs while traveling in Chile in 1834. Scientists who later studied the mouth-brooding animals found that there are actually two species, naming one Rhinoderma darwinii (Darwin's frog) and the other Rhinoderma rufum (Chile Darwin's frog).
From 2008 to 2012, a team of researchers led by zoologist Claudio Soto-Azat surveyed 223 sites in the frogs' historical range, from the coastal city of Valparaíso south to an area just beyond Chiloé Island. R. rufum has not been seen in the wild since 1980, and despite the recent extensive search effort across every recorded location of the species, no individuals were seen or heard during the four-year survey, the researchers said. R. darwinii, meanwhile, was found in 36 sites, but only in fragmented and small populations, each with likely less than 100 individuals.
The findings suggest Darwin's frogs have disappeared from, or at least rapidly declined in, many locations where they were recently abundant, the researchers wrote in a paper published online June 12 in the journal PLOS ONE. Habitat loss and fragmentation may be the culprits.

From the Reporter-Herald:
Scientists believe that a protein in (snake) venom helps snakes relocate their prey so they can continue their dinner.
This protein, called a disintegrin, enables the snake to relocate its prey, explains (University of Northern Colorado researcher Anthony) Saviola. He says scientists performed studies where a rattlesnake struck a mouse, and when a second rattlesnake of the same species was given a choice between that mouse or one that had not been injected with venom, the second rattlesnake usually always chose the one with venom.
Snakes also have an advanced olfactory system and special chemosensory organs in their mouths. Snakes will tongue-flick rapidly, says Saviola, to pick up chemical cues in the environment. But it appears to be the disintegrin that helps them find prey.
Integrins, by definition, are a large group of molecules that promote cell adhesion. "Some of these you don't see in normal, healthy tissue," says Saviola, "but you will see them expressed 100 fold in abnormal, cancerous tissue."
The disintegrin protein in snake venom, when injected into cancer cells, binds the outside of the cell via these integrin receptors. Chemotherapy, used most often to help stop the spread of cancer, not only kills cancer cells but also the healthy cells. The disintegrin from snake venom acts differently. "It doesn't kill the cell," says Saviola. "It binds the outside and doesn't allow the cell to communicate with surrounding cells. That's when cancer becomes cancer ... when it spreads throughout the body."

Not everyone starts out liking reptiles -- but that can change, as this profile of Hogle Zoo reptile keeper Emily Merola demonstrates.
From the Salt Lake Tribune:
Emily Merola can relate. The Hooper native and psychologist is Hogle Zoo’s primary reptile keeper. She takes care of 52-year-old Kronk, a huge Aldabra tortoise that sometimes follows her around like a puppy during feeding time, Bill and Hillary — the crocs, not the political couple — and an assortment of snakes, lizards, turtles, tortoises and amphibians.
"You have to work with reptiles to really appreciate the grand scale of them," she said. "They are unlike any animal that I have ever worked with before. They are kind of a challenge. You can’t read them like an ape or a giraffe. They don’t have facial expressions. They are the most laid back animals you could ever work with, and the most difficult."
Merola began her Hogle Zoo career volunteering and then serving an internship. She became part of the staff called Eco Explorers that took live animals or exhibits around the grounds and interacted with visitors. She took a seasonal position and, two years later, earned her way into the reptile supervisor position.

A donated $24,000 laser is helping the South Carolina Aquarium rehabilitate hundreds of injured sea turtles and another mammals, fish, and wildlife.
From the Herald Online:
An endangered Kemp's ridley sea turtle was fitted with a black hood and held quietly Tuesday as it received laser therapy for a joint injury that, under normal circumstances, could keep it in the South Carolina Aquarium's Sea Turtle Hospital for as long as two years.
The turtle, stunned by last winter's cold, has developed a bone infection. The aquarium's new laser will ease the creature's pain and is expected to reduce its recovery time.

The Global Conservation Group is offering a $1,000 reward for information leading to the arrest and conviction of the person or persons responsible for the fatal beating of a snapping turtle at the Delbrook Golf Course in Delavan, Wisc., on June 10 between 7:30 and 9:30 a.m.
The female turtle, looking for a place to lay her eggs, was found lying in the sand in a bunker with holes in its shell. She was also struck in the right eye, a wound which appeared to have been from a golf club. Investigators looked for her eggs but were unable to find them.
Anyone with information about this case should call the DNR hotline at 1-800-TIP-WDNR or 1-800-847-9367. Callers can remain anonymous.
If you would like to contribute to the reward fund, you can do so here.
A fungus that has killed snakes in Massachusetts, New Hampshire and Illinois has been identified in timber rattlesnakes in Tennessee.
From Nashville NPR:
Infected snakes have been located in Massachusetts and New Hampshire. Illinois has seen multiple fatalities over the last several years in a threatened snake species – the eastern massasuaga. While the total number of deaths is small, so is the total snake population in northern states like Illinois.
“Even a few individuals can be significant,” TWRA biologist Brian Flock writes in an email.
One of the leading researchers on the topic is wildlife veterinary Matthew Allender, who says the fungus that’s being discovered is often found on captive reptiles like bearded dragons. He told the University of Illinois News Bureau that finding infections in the wild is significant.

Sharjah, one of the United Arab Emirates, celebrated World Oceans Day last weekend by releasing a group of critically endangered hawksbill turtles to the Gulf of Oman.
From The National:
The global population of hawksbills, named for their narrow head and shape of their beak, has dropped by 80 per cent in just three generations despite international conventions banning hunting and trade.
They have been threatened in recent years by human encroachment, particularly construction and coastline activity that threaten coral reefs, one of the turtles’ natural habitats.
Other threats include fishing, pollution and eggs being stolen from nesting beaches.
The turtles released at the Mangrove Natural Reserve in Khor Kalba were found by members of the public and taken to Sharjah Aquarium, which has been running a programme to protect and rehabilitate the creatures for the past three years.
Ismail Al Bloushi, a marine biologist, has led a Sharjah Aquarium team rehabilitating turtles for their release.

A giant lizard, named after the Doors' Jim Morrison, who was dubbed "The Lizard King," once lived in Southeast Asia, sharing habitat and food sources with mammals.
From Science Daily:
A team of U.S. paleontologists, led by Jason Head of the University of Nebraska-Lincoln, describes fossils of the giant lizard from Myanmar this week in the scientific journal Proceedings of the Royal Society B. Their analysis shows that it is one of the biggest known lizards ever to have lived on land.
The creature's scientific name is Barbaturex morrisoni -- which means "Lizard King," in honor of the aforementioned Doors singer.
At almost six feet long and weighing upwards of 60 pounds, the lizard provides new and important clues on the evolution of plant-eating reptiles and their relationship to global climate and competition with mammals.
In today's world, plant-eating lizards like iguanas and agamids are much smaller than large mammal herbivores. The largest lizards, like the giant, carnivorous Komodo dragon, are limited to islands that are light on mammal predators. It is not known, however, if lizards are limited in size by competition with mammals, or by temperatures of modern climates, Head said.
But B. morrisoni lived in an ecosystem with a diversity of both herbivorous and carnivorous mammals during a warm age in Earth's history -- 36 to 40 million years ago -- when there was no ice at the poles and atmospheric carbon dioxide levels were very high. The creature was larger than most of the mammals with which it lived, suggesting that competition or predation by mammals did not restrict its evolution into a giant.
"We think the warm climate during that period of time allowed the evolution of a large body size and the ability of plant-eating lizards to successfully compete in mammal faunas," Head said.

Rumors of the Hula painted frog's extinction may have been premature.
The frog, declared extinct 60 years ago, has been discovered in Israel. From Science Daily:
The Hula painted frog was catalogued within the Discoglossus group when it was first discovered in the Hula Valley of Israel in the early 1940s. The frog was thought to have disappeared following the drying up of the Hula Lake at the end of the 1950s, and was declared extinct by the (International Union for Conservation of Nature) in 1996. As a result, the opportunity to discover more about this species' history, biology and ecology was thought to have disappeared.
However, a team of Israeli, German and French researchers now report in the scientific journal Nature Communications on an in-depth scientific analysis of this enigmatic amphibian.

While perusing Facebook a few days ago, an entry on the page of the Turtle Hospital at Marathon, FL, caught my eye. I first glanced at it then read it again:
This cute little guy was washed ashore and found floating in a bed of Sargassum weed inside a marina at The Sea Breeze Trailer Park in Islamorada. Because there was a large saltwater crocodile in the marina too the turtle was netted and turned over to the Turtle Hospital for rehabilitation. At just over 10cm long, Crush qualifies as juvenile Hawksbill and is probably less than a year old.
Hawksbill researcher Larry Wood had told me that although they were rare on the mainland, only a few miles to the east of Palm Beach, amidst the sargassum, hawksbills gathered and grew, probably for years, before dispersing. Each year some would disperse and a new cohort would appear.
Bette Zirklebeck, the Turtle Hospital manager, thought “it was likely that strong currents pushed this turtle (dubbed Crush) the wrong way and he floated in to shore.” Zirklebeck continued “Crush appears to be in pretty good shape and staff plans to give him plenty of squid bits and make sure behavior is normal before his release in just a week or two!”
Prior to the advent of fancy plastics, hawksbills were hunted for their shells and the intricately colored carapacial scutes were made into fancy jewelry and glasses frames. Hawksbills are an endangered turtle species and are rigidly protected over most of their wide range.
We wish Crush a lifetime of good luck.

The reptile exhibit at Zoo Atlanta is the oldest area in the facility. But the reptiles will soon have a shiny new exhibit, designed to display the animals in a more natural habitat and focus on giving children a herp's-eye-view at the same time.
From the Zoo's media release:
Something spectacular is coming to Zoo Atlanta, and the evolution officially began on June 4, 2013. At a gathering of elected and appointed officials, community partners and Zoo Atlanta leaders and staff, ceremonial shovels broke ground on Scaly Slimy Spectacular: The Amphibian and Reptile Experience, scheduled to open in late 2015.
Scaly Slimy Spectacular will represent the largest fundraising effort in the Zoo’s history. Zoo Atlanta has raised just under $22 million as part of an ongoing capital campaign to fund the roughly 14,000 square-foot experience, with a goal of raising an additional $1.4 million over the next few months.
“We’re standing on the cornerstone of a new era for Zoo Atlanta. Our community has shown willingness to make a significant investment in the future of the Zoo,” said Raymond B. King, President and CEO. “We hope that as the public aspect of our capital campaign continues, Zoo Members, families and guests will also want to play a personal role in seeing history being made with what will truly be a world-class experience for Atlantans and Georgians.”
Winter Johnson Group, a partnership of the Atlanta-based Winter Construction and Johnson Construction Services, has been selected as general contractor; Scaly Slimy Spectacular will be the company’s 22nd construction project. Project architects are Torre Design Group Consortium, Ltd.
Scaly Slimy Spectacular will replace the 51-year-old World of Reptiles, the Zoo’s oldest building still in use for public exhibits. The new complex will be erected on a separate site which has not been accessible to the general public in decades.
There are more than 450 reptiles and amphibians at Zoo Atlanta, but a sizable portion of these animals have not been on exhibit as a result of space constraints in the World of Reptiles. Scaly Slimy Spectacular will provide naturalistic new homes for members of the existing collection while introducing large crocodilians and other exciting new arrivals. The complex will feature interactive indoor venues and state-of-the-art exhibits showcasing the amazing extremes in size, speed, color and behavior that make reptiles and amphibians such compelling animals to observe, study, and protect.

Years ago, when I first moved to Florida, my then-boyfriend took me out to look for cage furniture. We needed pieces of dead wood, curled tubes of bark, odd bits of driftwood, clumps of moss, the sort of item that helps turn a cage from "pathetic" to "that'll do."
The boyfriend was living in north Tampa, not too far from wooded areas and the Hillsborough River, and he was a herper (required) so I was pretty sure he'd know good areas to look.
On that day, we parked by SR 301 (then a tiny two lane) and walked into the woods. We had really good luck and within a few hours our arms were laden with exactly the right sort of stuff. I said OK, let's head back. My boyfriend looked at me as if I suddenly was speaking German. "Head back?" he said. "Which direction?" A short silence followed while I just l looked at him. He gave a short embarrassed laugh. "The last time I did this, I had to spend the night and then find my way out by the sound of traffic."
I thought, this was the all-time clumsiest effort at seduction I have ever seen. Spend the night in the woods indeed, and there's not even a tent? Was this guy for real?

Pressures from the pet and fashion industries are straining monitor lizards in Southeast Asia.
From Live Science:
Some laws are in place to protect the dragon-like creatures from unsustainable hunting and harvesting for the exotic pet trade. But a new study warns that dealers may be overexploiting the reptiles, taking advantage of the scant information conservations have on many of these species in the wild.
In a report in the journal Herpetological Conservation and Biology, researchers assessed the distribution, threats and conservation status of species of monitor lizards that live in Southeast Asia and New Guinea.
[...]
Study researcher Mark Auliya, of the Helmholtz Centre for Environmental Conservation (UFZ) in Leipzig, explained in a statement that the lizards draw high profits because of their looks and rarity.
"Quite often four-digit amounts are paid, for pairs occasionally even five-digit sums," Auliya said. "Even the large Komodo dragons are illegally traded, although international trade regulations under CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) do not permit commercial trade of wild specimens of this species."

This “little project,” or more accurately long term fact-finding mission, started out years ago after several seasons of seeing my diamond pythons breed but not having my females ovulate. Why was this happening? What was I doing incorrectly? Well, I still don’t have the answer to these two questions, but while I was meditating on them I started the current project.
Diamonds are the southeastern most race of carpet pythons or, more correctly, carpets are more northerly and westerly races of the diamond python. It is well documented that diamond pythons at the northerly end of their range intergrade with the southernmost coastal carpet pythons. And, unlike the difficult diamond pythons, the southern carpets are easily bred. How about the diamond-coastal intergrades? Time to find out.
Pure diamond male
So I enlisted the help of Will Bird, owner and cage slave to a wonderfully varied collection of herps at Extraordinary Ectotherms. Will bred diamond and carpet pythons of varying lineages. To give the project a head start I borrowed a couple of first generation diamond-carpet babies and we were on our way.
Female 75 percent pure diamond
The babies matured and were successfully bred to one of my full blooded diamond males. She laid a few eggs amd voila, I had babies that carried 75 percent diamond genes. They matured and were bred to another diamond male and this year I have hatchlings with 87.5 percent diamond genes.
Newly hatched 87.5 percent diamonds, 2013
If continued, when these babies mature, the project will produce snakes having 93.75 percent diamond genes followed next generation by babies that are 96.865 percent diamonds. I’m hoping that these higher percentage diamonds remain easily bred, and I know they will look like pure diamonds. Ease of breeding added to the beauty of the diamond python should interest many hobbyists, old and new alike.

It's not every veterinarian who can say he's performed surgery on a rattlesnake. Dr. Scott MacLachlan in Poultney, VT, can, however.
From Vermont NPR's Ted Levin:
During the spring of 2011, the Vermont Department of Fish and Wildlife in collaboration with the Orianne Society and The Nature Conservancy began a two-year study of the summer range of the timber rattlesnake in western Rutland County.
To that end, transmitters were implanted in the body cavity of twenty-two adult snakes. From late spring through early autumn, the snakes were radio tracked across rough terrain west of Otter Creek. Now that that phase of the project has ended, and Dr. MacLachlan, who had inserted the transmitters, is removing them, as well as taking skin and blood samples from each rattlesnake to check for pathogens.
The day I observed the procedure, the operating room was well lit , with a sink in one corner flanked on both sides by a pink linoleum countertop. The floor was a soft white and textured like the back of a snake. There were cupboards, tanks, computers, glass-fronted cabinets filled with a diversity of surgical instruments, and an aluminum operating table situated beneath a hose descending from the ceiling. The hose, called a gas scavenger, delivers both anesthesia to put the snake to sleep and oxygen to bring it back. There’s a heating pad covered by a blue terry-cloth towel on the operating table to keep the snakes warm.

Want to do something about declining amphibian populations? It's as easy as 1-2-3.
Karen Lips is an amphibian ecologist and tropical biologist. She recently wrote a Live Science op-ed about her experience tracking frog populations in Panama, and those of other scientists doing the same thing around the world, showing devastating declines in frog numbers.
She wrote:
What was most concerning was that even widespread species we thought were relatively stable were declining. This matches with the many stories I hear from concerned citizens who say that they don't see or hear as many frogs in their backyards as they used to. Because those scientists spent the time to count amphibians, they were they able to detect the slow loss in those populations.
We need more studies like these that can go beyond the distribution of threats and can show us how amphibian populations respond to disease so that we can design appropriate conservation and management actions to protect those species.
For example, if population declines are slow and steady, we might have time to experiment with different management practices; but if populations are declining quickly, we might need to establish captive assurance colonies or take tissues for cryopreservation to protect evolutionary lineages.
Likewise, we need to know which age class, sex or subpopulation might be the limiting step in population recovery. If the problem is in the tadpole stage and none survive to become adults, then we might want to design a reintroduction program that adds more adults to the system. If adults are very rare, we might do better to add hundreds of eggs, tadpoles or juveniles to jumpstart recovery.
Numbers are also critical, she said, because the "IUCN Redlist makes decisions on the level of species endangerment based on the number of individuals and the number of populations, and how quickly those numbers are going up or down. The official listing of species is the first step in prioritizing research and conservation efforts to address those threats, and is used to dedicate funding and other resources."
What can you do as an individual? Contribute data to online databases like http://www.inaturalist.org, or get involved in other citizen scientist projects, she advised.
"Whether the frogs are increasing or decreasing," Lips wrote, "we need to know: Just how many frogs are there?"
