Using computer models of jacky dragons, researchers have learned it's the order of a jacky dragon's movement that makes communication possible.
From Johns Hopkins:
Woo and Rieucau conducted a playback experiment using computer animations of lizard displays. They created three simulated animations of lizards that differed in their shape and skin texture and performed the displays either with natural syntax or reversed syntax. There was the “cyberlizard,” which had normal shape and skin texture; a lizard with normal shape but without realistic skin texture; and an object shaped generally like a lizard but lacking texture.
The researchers found the order of the actions was critical for signal recognition. Even the animated lizards with abnormal shape and texture elicited responses from the jacky dragon subjects, as long as the actions were in the correct order.
The lizards responded to animations with correct syntax by making social signals of their own. These included aggressive signals like fast head bobs or the entire visual display pattern (tail flick, quick arm wave, and push-up body rock) or submissive displays like slow arm waves and slow head bobs.

85 million year old aquatic reptile fossils were found in Israel, a reminder of a time when Israel was covered in water.
From the Jerusalem Post:
“This is the first time that a fossilized animal like this has been found in Israel during this period,” she said. “It’s very rare for an animal like this to be fossilized.”
Researchers found roughly 30 fossilized remnants of the reptile known as the Elasmosaurus, which Ashckenazi- Polivoda described as the “cousin of dinosaurs.” It was 8 meters long, with its elongated neck constituting a third of its body, she said.
“The most exciting thing is that this is the first time that a single species’ bones [of this type] were found in the same place here,” she added. “We’ve found similar fossils from 10 million years later, but never during this time.”

Years of studying redtail coral venom has finally paid off.
From Johns Hopkins:
For more than a decade, a vial of rare snake venom refused to give up its secret formula for lethality; its toxins had no effect on the proteins that most venoms target.
It comes from a reclusive redtail coral snake, or Micrurus mipartitus, which is primarily found in Costa Rica and parts of South America.
But recently, an international team of researchers figured out the venom's recipe—a toxin that permanently activates a crucial type of nerve cell protein, causing deadly seizures in prey. The details were published online in the Proceedings of the National Academy of Sciences on Monday.

A new water frog species was discovered in a place thought to be thoroughly explored.
From sci-news.com:
The specific name ventriflavum comes from the Latin venter, meaning belly, and flavus, meaning yellow and refers to the golden yellow and orange coloration on the body.
The populations of several species of the water frog genus Telmatobius have declined dramatically over the past 30 years, and the genus is now thought to be extinct in Ecuador. These declines have been associated with the spread of the fungal disease chytridiomycosis.
Telmatobius ventriflavum was discovered in the species-poor coastal valleys of central Peru, a region well studied but apparently still hiding surprises.

Conjoined Quince monitor lizard twin, who were dead before hatching, were found in a zoo in 2009.
From Live Science:
It is possible that the reason the lizards were conjoined was partly due to the low amount of genetic variation that stemmed from having parents that were siblings, according to the report. In 2002, research was published on snakes, called Natrix tessellata, which showed a link between an increased rate of developmental abnormalities and a low genetic variability in small populations that had a limited number of ancestors.
Moreover, a study on sand lizards "revealed a significant effect of parental genetic similarity on the risk of hatching malformations," van Schingen said.
However, previous reports have also pointed to other potential causes of malformations in reptiles. For instance, in 2010, researchers described a case of a crocodile hatchling with eight legs and two tails in Venezuela that was found in an area that was exposed to chemicals from agriculture, according to the report.Another cause of deformations in reptiles may be adiet that is not well-suited to the needs of animals kept in captivity, which has previously been the case with bone malformations in green iguanas, van Schingen said.

One police officer brought a blue-tongued lizard into the station 30 years ago, and lizards have had a home there ever since.
From ABC News Australia:
The site now has a purpose built courtyard for the lizards which are mascots for the station.
Cheryl Hackett, the Belconnen Station's administrator, said being the chief lizard carer at the site was on the job description when she took over the role last year.
"They're beautiful, they really are, I never had a lizard, never owned one but I just love 'em," she said.
Earlier this week the lizard population at the station swelled from eight to 18 when one of the females gave birth.

The alligator population in North Carolina is growing, but allowing a hunting season may hurt their long-term security.
From newsobserver.com:
Moorman, coordinator of N.C. State’s fisheries, wildlife and conservation biology program, said he couldn’t estimate the state’s overall population. He said the survey didn’t try to tabulate all possible gators. They’ve shown up in recent years in inland waters as far west as Harnett County, which is between Raleigh and Fayetteville.
An alligator hunting season could manage growing populations and potential nuisance gators, offer a hunting opportunity to sportsmen and sportswomen, and provide revenue from permit sales to fund the monitoring of populations.
Nevertheless, “alligators in North Carolina may be more vulnerable to environmental stochasticity (randomness), including harsh winters and frequent hurricanes, than elsewhere, so predicting long-term effects of a sustained hunter harvest is especially difficult,” the researchers cautioned.

A 7 year old iguana named Godzilla is back with her owners after the thief sold her to a pet store.
From ABC News:
The reptile-napper was caught on surveillance camera snatching Godzilla from her outdoor sanctuary in front of Paramount Pet Enterprise on Monday.
Store owner Holly Cepeda said Godzilla is well-known in the community, and she regards her as part of her own family.

Seeing a loggerhead turtle tangled in a net, surfer Mitu Monteiro did the only sensible thing - he rescued the turtle.
From the New York Post:
Mitu Monteiro, 31, had spotted the Loggerhead while catching waves at Serra Negra Beach on Sal Island in Cape Verde, Africa after the little fella became tangled in a plastic net, Caters News Agency reports.
Upon further inspection, Monteiro noticed the neck and fins of the turtle were terribly entwined in the frayed edges of the packaging.
Thinking fast, the heroic surfer scooped up the turtle, placed him on his board and sailed back to shore — where the net was removed with the help of other surfers, according to Caters.

Melbourne is building a new venom library, where researchers can investigate new anti-venoms and medicinal uses for venom.
From the Guardian:
Over the past six months, scientists have collected 12 snakes and milked them of their venom. The snakes have been stored in a fluid preservative.
The snakes belong to the tiger snake lineage of species, with variants including two species of copperhead snake, a white-lipped snake and a small-eyed snake.
The venom library will progressively add other species, such as blue-ringed octopus, spiders, scorpions, platypus – which has a venomous spur - and other snakes. It will be the first facility in Australia to have a dedicated storage of venom along with full tissue samples of the animal the poison has been extracted from.

Students and staff at a Vermont college are worried after the school's rainbow boa disappeared.
From WPTZ News:
School officials say a boa constrictor disappeared from its cage at the Jeffords Center over the weekend. Students had a snow day Monday. On Tuesday, the professor who owns the snake discovered it was gone.
"I didn't know there was a snake on campus before now, it's kind of scary," said Justin Goulet, a sophomore.
The Castleton Community received an email this week alerting them that the 4-foot long rainbow boa was "thought to [have been] stolen from a lab."
"Based on what we've seen so far we tend to think it's been taken based on the snake's usual habits," said Dikeman. "It tended to be shy and timid, and doesn't like to be outside of a warm tropical environment."

An Australian carpet python was caught in the middle of snacking on a possum.
From the Courier Mail:
Sunshine Coast snake catcher Stuart McKenzie said while carpet pythons are common across the north coast he’s never come across one dining out.
Mr McKenzie said the python was as big as they come.
“This is one of the bigger ones I’ve come across as a snake catcher,” he said.
“A lot of the time as snake catchers we’ll get to the property and the chicken or the guinea pig will already be in its belly, so it’s pretty awesome to see it halfway through.”

A fossil discovered in China shows some good parenting from a now extinct reptile species.
From Live Science:
Given that all of these animals died within a tail's length of one another, it's likely that the adult was caring for the young, they said.
"Although it is possible that the individuals were all swept together during or soon after the event that killed them, it is [felt] that this specimen more likely represents an instance of postnatal parental care," the researchers wrote in the study.
Parental care is seen in other animals, including crocodiles and birds, which lived during the time of the dinosaurs. For instance, crocodiles defend their young from predators, and birds protect and feed their young, the researchers said.

Walking around Australia to raise money for a hospital, a man's stormtrooper suit saved him from a king brown snakebite.
From the New York Daily News:
"The armor actually protected me and stopped the bite," Loxley said in a video posted online.
"I could feel the teeth on the plastic, scraping, but the armor actually stopped something," he said.
"So all those people that rag on the old stormtroopers, you know, 'the armor doesn't do this it, doesn't do that', it stopped a snake bite and probably saved my life today," he added.
The former soldier is walking around Australia dressed as a stormtrooper to raise $80,000 for the Monash Children's Hospital in his home city of Melbourne.

Worried about federal overreach, and because they're "creepy," lawmakers rejected a bill championed by a local school girl to name the Idaho giant salamander the state amphibian.
From the Star Tribune:
Frank Lundberg, a herpetologist, testified in support of the bill and was disappointed after it failed.
"It is a mistake to ever overestimate the ignorance of the Idaho Legislature," he said.
Idaho fourth grade classes study state symbols as part of Idaho history, and a fourth-grade teacher backed the bill as well.
But Rep. Ken Andrus, R-Lava Hot Springs, voted against the salamander after recalling being repulsed by them as a young boy.
"They were ugly, they were slimy, and they were creepy," he said. "And I've not gotten over that. So to elevate them to the status of being the state amphibian, I'm not there yet."

After a snake common in Sri Lanka was found in India, scientists now suspect the two countries were once connected by land.
From the International Business Times:
The snake can jump five metres and disappear in a trice, says wildlife biologist Bubesh Guptha who has spotted it near the temple town of Tirumala in the state of Andhra Pradesh.
Around three feet long and sporting big eyes and skin patterned in ash and olive green, he has spotted the same species twice in and around the same hills.
The mildly venomous tropical snake Chrysopelea taprobanica eats bats, lizards, geckos, smaller snake species, skirls and birds, reports Nature Asia.

A search by conservationists in Oregon for western pond turtle eggs yielded none.
From the Statesman Journal:
Oregon Department of Fish and Wildlife conservation biologist Susan Barnes called the failure to spot a single individual at 15 sites “moderately alarming.”
“It’s clear that there are not a lot of turtles out there, but it will take more years of data to understand what’s happening with local western pond turtles and why,” said Barnes, who oversaw the survey.
Pond turtle populations have declined throughout their West Coast range for a number of reasons, including destruction of their wetland habitat, conflict with invasive species and a recently discovered shell disease.

An 8th grader in Idaho is pushing her representatives to declare the Idaho giant salamander the state amphibian.
From the Spokesman-Review:
The young woman has been pushing the bill for five years now, and last year, it passed the Senate on a 33-2 vote. But it never got a committee hearing in the House. “In all fairness to her, we were really at the end of the session last year, and we had an awful lot to do,” Loertscher said. “It doesn’t mean that I’m going to vote for it, but in fairness to her, I thought it should be heard.” He said he’s expecting to set a hearing on the bill for early next week.
“I think that the Idaho giant salamander is the best candidate to represent our state,” Ilah told the State Affairs Committee this morning. “It has ‘Idaho’ in its name. The pattern on its skin looks like a topographical map of the Bitterroot Mountains. And it makes its home almost exclusively in Idaho.” She called the salamander an “intriguing animal” and said its designation as a state symbol could help engage students, like her, in learning about Idaho.

With a recent discovery of a new species, the total of different types of tree frog living in Vietnam is up to 73.
From Vietnam Net:
The new species is named Kurixalus motokawai to honor Dr. Masaharu Motokawa from Kyoto University. He is a researcher of mammals and has made many contributions to the study and conservation of biodiversity in Vietnam.
This is the second species of Kurixalus tree frog discovered in the Central Highlands in 2014, bringing the total number of species of tree frog in Vietnam to 73, accounting for 20% of all species of tree frogs of the world.

Over a decade ago, a boy found one of the most complete reptile fossils of the Carboniferous era on his farm on Prince Edward Island.
From CTV News:
"This specimen is really rare," said Modesto, who was the principal investigator of the project. "It's the only specimen we know of from this particular part of the Carboniferous and it's the only reptile from that slice of time."
The research will be published in the journal Proceedings of the Royal Society B on Wednesday.
Modesto said the fossil was discovered by a boy and his family on their farmland in Prince County, P.E.I., more than 14 years ago. It was taken to the Royal Ontario Museum in 2004 and about four years ago, Modesto and his team started their research.
The fossil, erpetonyx arsenaultorum, was named after the Arsenault family who made the discovery.

One man got more than he bargained after he discovered a live snake in his grocery bag.
From the Chronicle Live:
Dean thinks the snake may have been curled up in a pair of thick socks which he had also bought on Saturday’s shopping trip.
He added: “I think it’s maybe been keeping warm in them before coming out once I arrived back.”
Wayne Mailer, who runs Dragons Den Exotic Pets in Newcastle, said: “Looking at the picture, this appears to be an Amery Corn Snake.
“I think it’s probably only a hatchling maybe only a few weeks old . At the minute it doesn’t appear to be in the best of health, probably due to the cold weather.
“More than likely, it is an escapee pet.”

While some species are suffering due to drought, leaf litter frogs are struggling with too much rainfall.
From the University of New Mexico Newsroom:
Using four different species of leaf litter frogs, they replicated and sampled 10 plots per year, using a plot survey technique of total leaf litter removal within each plot. They measured and sampled annual species diversity and community composition once a year during March, during the dry season, at the Organization of Tropical Studies Las Cruces Biological Station in southern Costa Rica.
Their findings were surprising in that strictly terrestrial frog species (i.e., they do not breed in water) can be influenced by extreme rainfall events much like their aquatic-breeding counterparts. The researchers discovered that species diversity and the community structure changed negatively in dramatic fashion from the two pre-La Niña years compared to the onset of the La Niña event in 2010.
The altered community structure due to extreme rainfall lasted for over 20 months. During that time, all four leaf litter frog species declined in number and several measures revealed marked changes in the community structure in terms of both plot diversity and occupancy.

Used in food and folk medicine, Thai fishermen may be catching too many sea snakes.
From National Geographic:
Some scientists are raising concerns about the practice. Little is known about the region's sea snakes, including what species and how many live there, so it's not clear whether the harvest is sustainable.
An overharvest, these researchers worry, could jeopardize potential medicinal discoveries. Compounds in venom, once processed and administered in controlled amounts, can be beneficial in treating human ailments like heart disease.
The sea snake catch—a side job for the region's Vietnamese squid fishers—takes in over 80 tons (73 metric tons) of the marine reptile annually. That's roughly 225,500 individual sea snakes per year, valued at over $3 million.

Easily confused for snakes, a new type of caecilian, or legless amphibian, has been discovered.
From phys.org:
"The I.cardamomensis species is only the second caecilian species ever discovered in Cambodia. The other is the striped Koa Tao Island caecilian, I. kohtaoensis, which is also found in, Laos, Myanmar, Thailand, and Vietnam.
These discoveries are important to demonstrate that much of Cambodia's biodiversity remains unknown and unstudied by science, and many more areas need to be searched," Thy said.
The forested Cardamom Mountains Range represents some of the largest remaining areas of habitat for more than 80 threatened species, including Asian elephant and gaur.
Thy said in recent years the Cardamom region had revealed its extensive reptile and amphibian diversity, including frogs, turtles, lizards and crocodiles.

Could a universal anti-venom be just around the corner?
From Tech Times:
Scientists from the Liverpool School of Tropical Medicine (LSTM) are working toward the development of a universal anti-venom that can be used for the bite of all of the snakes in sub-Saharan Africa with the aid of a new technique dubbed antivenomics.
The technique can help improve the potency of extracting snake venom and thus the potency of the antidote. Scientists hope that this breakthrough could help save thousands of lives per year.
In sub-Saharan Africa, snake bites cause the death of 32,000 people per year. Some of those who manage to survive likewise suffer from serious effects with snake bites permanently disabling 96,000 people in the region annually.

Think all frogs lay eggs? Think again.
From ScienceBlogs:
A new species of frog (Limnonectes larvaepartus) has been discovered in the rain forest of Sulawesi island in Indonesia. This species challenges the grade-school wisdom that taught us: ‘frogs lay eggs’. It looks like textbooks will need to be revised as this is the only known exception to that rule. Study author Dr. Jimmy McGuire (University of California, Berkeley) said the following as quoted in Reuters, “Reproduction in most frogs could not be more different from human reproduction. In this case, what is most interesting, ironically, is that the reproductive mode is more similar to our own.”

Smugglers attempted to pass almost 200 baby radiated tortoises through Paris.
From PressTV:
The rare reptile species are known as "radiated tortoises" and found only in Madagascar, customs officials said. The one-of-a-kind pattern on their shell case makes them precious for collectors.
The baby reptiles, 15 of which had died, were discovered in a crate carrying sea cucumbers on December 14. The officials added that "particularly unsuitable conditions of transport," was the cause of their death.
Those that have survived have been transported to Tortoise Village in France's southeastern Var region.

The Lower Keys can now join the Everglades as home to breeding populations of both American alligators and crocodiles.
From Keys News:
If she and Cherkiss are correct, then the Lower Keys have joined the Everglades as home to breeding populations of alligators and crocodiles.
Unlike the Upper and Middle Keys, the Lower Keys have long been home to a small community of alligators. The famed Everglades denizen is one of the main draws at Blue Hole, an old railroad quarry in the Key Deer refuge that has evolved into a rainfall-fueled freshwater lake. Alligators also make homes on other parts of Big Pine, as well as surrounding Lower Keys islands, where the limestone bedrock is of a less porous variety than the keystone bedrock of the northern island chain. As a result, those islands retain enough freshwater during the dry season to provide acceptable, if not especially good, habitat for freshwater-dependent alligators.
Lower Keys promoters now can decide whether to follow the path of Everglades backers by promoting the fact the area harbors both alligators and crocodiles. After all, the area already focuses much of its marketing resources around its attributes as an ecotourist destination.

A fraction of the size of its cousin the Komodo dragon, a recently identified Australian goanna could fit in your hand.
From the Scientific American
Lizards don’t get much bigger than the Komodo dragon (Varanus komodoensis), which can reach three meters in length and may weigh as much as 70 kilograms. But not every member of the Varanus genus is a giant. Scientists in Australia last month unveiled the newest Varanus species and it’s as small as the Komodo is large. The newly discovered Dampier Peninsula goanna (V. sparnus) is just 23 centimeters long and 16 grams in weight. That’s about the size of a human hand, which would barely count as a nibble for a hungry Komodo dragon.

It may sound like an urban legend, but one woman got the surprise of her life after finding a boa in her bathroom.
From the L.A. Times:
"I thought my eyes were deceiving me," Lasca said. When she saw the flicker of the snake's tongue, she knew it was a snake.
She screamed and ran from the bathroom, slamming the door and calling the county Department of Animal Services.
The snake, identified as a Colombian rainbow boa, was curled up behind the toilet when an animal services employee arrived at the office in a building at 5th and G in downtown San Diego, which was once city hall.
