Once considered to be non-existent in Angola, a new study reveals the country is home to Gabon vipers.
From SpyGhana.com:
Bitis Gabonica, commonly known as the Gabon viper, is a venomous viper species found in the rainforests and savannas of sub-Saharan Africa. It is not only the largest member of the genus bitis, but also the world’s heaviest viperid, and it has the longest fangs and the highest venom yield of any venomous snake.
Angolan scientist Paula Regina de Oliveira said the species of Bitis Gabonica are the ones with teeth that could reach five centimeters long and larger glands, which allow them to accumulate large amounts of venom.

The Florida Fish and Wildlife Conservation Commission is offering workshops to help people identify and report Burmese pythons, but not everyone agrees that the pythons are a problem.
From WUFT News:
"This horse has been beat so many times," said Eugene Bessette, commercial snake breeder and owner of Ophiological Services, a snake farm on Archer Road.
Even though Burmese pythons are not indigenous to South Florida, Bessette said he feels they are ultimately not an ecological problem.
"Ignorance is the biggest problem," Bessette said. “People form opinions before they get the facts."
Bessette lost a substantial part of his business when new regulations put in place in 2012 banned the importation and interstate transportation of Burmese pythons and three other constrictor snakes.

After finding a turtle barely alive, two little girls insisted their parents take the turtle to a "turtle doctor," and a local aquarium offered help.
From BizNews.com:
The aquarium was overseeing the rehabilitation of baby Loggerhead turtles found washed up along the Cape Coast predominantly in Struisbaai.
The family drove the turtle to the aquarium, where staff were on hand to meet them.
“Rosie was put into the rehabilitation tank along with the 178 other Loggerhead turtles currently in their care and by Sunday morning Two Oceans Aquarium staff confirmed that Rosie was doing well and appearing to be strong and healthy much to the delight of the Campbells,” Lambinon said.
He said of all the 179 Loggerheads found along the Cape coast to date, Rosie was the found the furthest south.

Inspired by poison dart frogs, an engineering professor developed a new way to construct airplane wings that keeps them from becoming icy.
From CNET:
Rykaczewski, an assistant professor of engineering at Arizona State University, was inspired by the bad-ass dart frog to devise a new type of artificial anti-ice "skin" for airplane wings. His research, which was conducted with several colleagues, was included in the latest issue of Advanced Materials Interfaces, published this week.
In the same way that dart frogs hold their venom beneath their outer skin and release it when they're in trouble, Rykaczewski's skin has two layers. The bottom layer contains an antifreeze liquid, and the outer layer is made from a superhydrophobic material, which means it is crazy good at repelling water. The outer layer also has a series of pores in it through which the antifreeze can be released.

Scientists recently discovered the first vertebrate that can change its skin texture.
From National Geographic:
On a nighttime walk in 2009, scientist Katherine Krynak spotted a well-camouflaged, marble-size amphibian that was covered in spines. But when she brought it inside, suspecting it was a new species, Krynak found a rather smooth and slimy critter.
"I was so mad at myself! I thought I had brought back the wrong frog," said Krynak, who was surveying amphibian species in the Reserva Las Gralarias.
She hadn't. When she tucked a small piece of moss in the frog's container to make it more comfortable before releasing it back into the forest, the spines slowly reappeared.
"It was shocking. Vertebrates don't do that," she said. Inspired by its spiky physique, she dubbed it the "punk rocker" frog.

Could Australian cane toads be shipped to China for medicinal uses?
From the Daily Mail:
Their venom could be effective in fighting cancer, researchers have discovered, and the potency of Australian cane toad's venom is stronger than those in China.
This means that potentially millions of toads could be shipped to China, so they could have their venom extracted and turned into medicine, to be sold on the multi-billion dollar traditional medicine market.
Harendra Parekh, from the University of Queensland's pharmacy department where the research took place, said this discovery could lead to a 'potentially a very lucrative export market'.

UK herp lovers are encouraged to create wildlife ponds to shelter newts.
From Express & Echo:
The Smooth Newt is the species most commonly encountered in garden ponds and we can all do our bit to help them, as Dr Wilkinson explains.
"Everyone can help by having a small, or large garden pond populated by native aquatic plants and kept free of fish which will eat young newts," he said.
Amorous amphibians are a key part of UK springtime, so this year why not forgo the frogs and instead nurture a newt by digging a wildlife pond.

Some costly antivenoms may soon be replaced by opossum blood.
From Chemistry World:
But treatments are costly and inaccessible for many people. Most antivenoms are made by injecting dilute venom into a mammal, such as a horse or rabbit. This results in an immune response, and the animal’s serum is then processed so that it can be injected into snakebite victims to scavenge toxic molecules in their blood. Such treatments typically cost $100-150 (£60-100) per dose, a prohibitive price for many people in developing countries.
But a team led by Claire Komives from San Jose State University has identified a protein from the blood of opossums – animals known for their ability to survive snake bites – that can be produced in large quantities by engineered bacteria, and shows promise as an antivenom.
In studies carried out on venom-exposed mice, those that were given just the venom died within 12 hours, while those that received the same amount of venom but were treated with the opossum peptide exhibited no ill effects. ‘Basically, the venom was completely neutralised,’ explains Komives, who was speaking at the 249th ACS National Meeting & Exposition in Denver, US. The peptide could protect the mice from the venoms of western diamondback rattlesnakes and Russell’s vipers.

Human and other primates may have evolved keen eyesight to detect dangerous snakes.
From NPR:
In a new paper published in the journal Primates, author William C. McGrew, a former professor of evolutionary primatology at the University of Cambridge, reports a high rate of venomous snake encounters by his team of primatologists seeking to observe unhabituated wild chimpanzees in Mount Assirik, Senegal, West Africa.
McGrew's snake-encounter analysis in the paper Snakes as hazards: modelling risk by chasing chimpanzees is one test of what's known as the snake-detection theory of primate origins, a set of hypotheses that suggest we (along with other primates) owe certain features of our evolution to the risks posed by death and injury from snakes.
During the 609 days that make up the core period of the analysis, McGrew and his team encountered a snake in Assirik, on average, once every 4.3 days — totaling 132 snake encounters. During the entire study period of four years, 142 snakes of 14 different species were identified. Of these, 64 percent were venomous: 33 cobras, 27 vipers and 24 rear-fanged snakes.

A Canadian paleontologist identified the remains of several endangered species smuggled from Hong Kong.
From the Calgary Herald:
Don Brinkman, a paleontologist at the Royal Tyrrell Museum in Drumheller, has been studying turtles for three decades and had assisted with previous investigations by Environment Canada.
But this case — which involved combing through a container with 945 turtle plastrons (bottom part of the shell), 2,454 turtle shells, and 52 bags of turtle fragments within 815 cartons, followed by a second container with 224 bags of fragments in 842 cartons — was the biggest Brinkman has ever worked on.
After three days in a Vancouver warehouse sifting through piece after piece, the lone scientist in a room full of officers, Brinkman helped bring the probe to a conclusion by identifying five endangered turtle species and three endangered tortoise species.

Remind your friends in Florida to leave nesting sea turtles alone, and avoid using bright lights near the turtles.
From WINK News:
The Florida Fish and Wildlife Conservation Commission (FWC) asks people not to get too close, shine lights on, or take flash photos of nesting sea turtles.
Spring is the beginning of sea turtle nesting season in Florida. From now through the end of October, thousands of sea turtles will land on Atlantic and Gulf coast beaches to lay their eggs. With Florida hosting one of the largest loggerhead nesting aggregations in the world, this becomes an opportunity for residents and visitors to play an important role in conserving these long-lived reptiles. People can help by taking turtle-friendly precautions on the beach.
“Take care when you’re on a Florida beach at night and do not disturb the nesting sea turtles,” said Dr. Robbin Trindell, who leads the FWC’s sea turtle management program. “People can help save threatened and endangered sea turtles by giving them enough space and privacy to safely and successfully lay their eggs. It’s as simple as keeping your distance and avoiding shining lights or taking flash photos of the nesting sea turtles.”

Chytridiomycosis is present in frogs from Madagascar, but for some reason they haven't developed the disease.
From QZ.com:
Madagascar has the 12th highest rate of amphibian species richness in the world, with more than 400 species, 99% of which are indigenous to the region. But this biodiversity hotspot is already under severe pressure—a quarter of its species are under threat, according to the latest Global Amphibian Assessment. It’s rightly feared that the arrival of Bd, as reported in the journal Scientific Reports, could bring about mass amphibian decline—and even extinctions—as has been seen elsewhere.
Testing of the samples of the Bd fungus found in Madagascar reveals the strain is closely related to BdGPL, the hyper-virulent lineage behind all the known outbreaks of the chytrid fungus pathogen that have decimated amphibian populations. However, what’s interesting is that the rate of infection is extremely low and there’s no clinical signs of chytridiomycosis—the frogs have the fungus, but they haven’t developed the disease.

Wildlife experts suspect this python became too much for its owner to handle, so he or she released it into the English countryside.
From Sky News:
"There are specific offences under the Wildlife and Countryside Act and Animal Welfare Act in relation to releasing a python and we would urge anyone with any information as to where the python came from to contact us.
"It is a possibility that the python may have outgrown its home and owners can contact Pip Reptile Rescue if they require any help or advice about caring for or rehousing reptiles.
"Similarly, we would urge anyone thinking about getting rid of their pets, particularly those which may pose a risk to the public, to contact an animal charity for advice so that they can be rehomed safely and responsibly."

The first reported case of black-and-white tegu necrophilia occurred in Brazil.
From the National Geographic:
The scientist returned to the same spot the next afternoon. By that time, the corpse was bloated and had begun to rot and smell.
But even the stench did not discourage another male black-and-white tegu from attempting to have sex with the dead body—this time for nearly an hour.
During this time, the new male embraced the dead female and bit her head, another courtship behavior. He rested on her body from time to time, taking breaks from the exhausting sexual activity, before finally flicking his tongue on the corpse and leaving, according to the study, published in January in the journal Herpetology Notes.

Not willing to let construction disturb the snakes they visit, several elementary school students organized to save them.
From the Delta Optimist:
The garter snakes had to be rescued as construction crews were scheduled to begin work on a section of the Boundary Bay dike. The students - Ben, Maya, Nic, Jude, Noah, Myles, Jasmine, Kaelyn and Lauren, who are in kindergarten through Grade 5 - were shocked when they heard about the impending construction.
All frequently visit the area to search out the snakes.
"We've all been going to the snakes since we were babies," said Kaelyn.
During the spring and summer, the snakes are active in the area and the kids often visit the beach, for class and after school, to play with them.
"The snakes, to me, are sort of like family," said Maya.

A North Carolina aquarium is training people to help with FrogWatch USA.
From Star News Online:
FrogWatch USA, a citizen science program, is now recruiting trained volunteers to collect data about the calls of local frogs and toads at local wetlands sites now through August and submit the data online.
“Amphibians are important species to keep an eye on because they are very sensitive to changes in their environment,” said Andy Gould, aquarium outreach coordinator. “If we see them in our area, it means that our habitats are healthy and thriving. If we notice their absence, we may want to look further into potential causes.”
No scientific background is required to volunteer, and those who want to participate will receive a free, four-hour training session that includes hands-on demonstrations and other educational activities to help them get acquainted with the native amphibian species they might encounter in Southeastern North Carolina.
