- Neil Balchan is upset, and so am I. The garter snake researcher visited a wintering den where he was doing field research only to discover that dozens of harmless red-sided garter snakes had been beaten and butchered at the site. CBC News has more.
- Here’s TVO on the fragile state of the eastern hognose snake in Ontario.
- And here’s the Great Lakes Echo on scientists’ efforts to track the elusive—and, in Ontario, endangered—rat snake.
- The Tennessee Aquarium has created the first map of North America’s biogeographical turtle communities.
- Burmese pythons might be an invasive scourge in Florida’s Everglades, but they’re not doing well in their natural range. The Guardian looks at conservation efforts on the python’s behalf in Bangladesh.
- An interesting read in Smithsonian magazine about taxonomic vandalism—the act of exploiting international rules to name new species without the science to back it up, usually for self-aggrandizing reasons. It’s endemic in herpetology; Raymond Hoser’s name turns up here, and not for the first time.
- Tiger keelback snakes are both venomous (it’s a rear-fanged colubrid)
and poisonous, thanks to the toads they feed on. The snakes store the toad toxins in their nuchal glands. But do they know they’re packing toad toxins? According to a new study, yes: the snakes’ defensive behaviour changes depending on the toxicity of their diet. [Journal of Comparative Psychology]
- Commercial reptile collection has been banned in Nevada, where it’s been more or less unregulated for decades. Nature’s Cool Green Science blog has the story behind the ban.
- Sean Graham has some advice for field herpers: instead of spending money and effort on finding rare species for your life list, they should spend that on field work that might actually do some good. “Imagine if instead of trying to find their lifer Pigmy Rattlesnake in Apalachicola National Forest, they instead went looking for them in central Alabama where records are few and patchy? If instead of herping for fun, everyone made their herping count?”1
- Using the Internet to identify snakes is definitely a thing; I’ve gotten my share of requests. Sierra, the Sierra Club’s magazine, looks at how the Snake Identification Facebook group does the job. Turns out the challenges the group faces are as much about social dynamics—dealing with frivolous requests, not attacking people for killing snakes—as they are scientific.
- If you can’t feed a snake mice, does that mean you can’t keep snakes at all? I answer this question on Quora.
- Known from only a handful of specimens since its discovery in 1937 and feared extinct, the Albany Adder (Bitis albanica) was found alive and well—at least four specimens were—last November, in a South African location that is being kept secret to deter poachers. Because yes, poachers will collect the shit out of these snakes.
- The plan to reintroduce Timber Rattlesnakes (Crotalus horridus) to an island in the Quabbin Reservoir in Massachusetts has been suspended in the face of local opposition; the Worcester Telegram’s outdoors writer Mark Blazis is disappointed.
- Ontario Nature has announced its new and improved Ontario Reptile and Amphibian Atlas app, which isn’t so much an app as it is a mobile website that supports offline data. Anyway, it’s got a field guide and lets you enter species sightings.
- Fossil snakes are generally known from their vertebrae, which makes their study a little less exciting to the lay reader than dinosaurs; still, it’s rather exciting that a new extinct species, Zilantophis schuberti, has been described from a fossil found in eastern Tennessee. “Zilantophis bore uniquely broad wing-shaped projections on the sides of its vertebrae. In life, these were likely attachment sites for back muscles. These features are what inspired the name of the new genus, derived from Zilant, a winged serpent in Tatar mythology.”

- Blind snakes (Scolecophidia) are tiny, secretive and easily overlooked; even so, there’s something of a blind snake renaissance going on, says Andrew Durso. “I recently noticed, much to my surprise, the the number of described species of blindsnakes has doubled in the last 13 years, from 305 in 2004 to 599 today; that’s 16.5% of all snakes! There are certainly many undiscovered species of blindsnakes, so it’s likely that their numbers will continue to grow.”
- A fascinating article in The New York Times Magazine from Daniel Engber that looks at the increasing use of the Burmese Python (Python molurus bivitattus) as a laboratory animal, and the possibility that its extraordinary digestive system—which has to flip from inactive to a 50,000-calorie meal all at once—may help find a cure for diabetes.
- Atlas Obscura on the comeback of the only remaining rhyncocephalian, the tuatara (Sphenodon). Breeding programs having more tuataras than they know what to do with is a nice problem to have. (I know people who, through zoo connections, have handled tuataras. I’ve never so much as seen one in the flesh.)
- Kenya has banned the export of various snakes, including the African Rock Python (Python sebae), due to the impact of collecting and poaching on wild populations. I would have thought that there wouldn’t be much demand, relatively speaking, for the large and nasty African Rock Python, but they’ve been collected so much that, like overfished species, their full-grown size in the wild has diminished.

- A plan to reintroduce the Timber Rattlesnake (Crotalus horridus) to an island in the Quabbin Reservoir in Massachusetts is running into opposition from local residents, though the island is a more isolated and remote reintroduction site than just about any other alternative. [via]
- The discovery of a rattlesnake in a Texas home led to 23 more turning up in the cellar, where they’d been overwintering.
- Ceal Klingler writes about the time that a Panamint Rattlesnake (Crotalus stephensi) came by for a visit. [via]
- That Arizona bill allowing snakes to be shot within city limits — which I mentioned in my last roundup — has apparently passed.
- The Mexican Garter Snake (Thamnophis eques) is endangered in Arizona, so residents presumably still can’t shoot it. It was believed to have disappeared from the Colorado River system, but it was recently spotted near Lake Havasu City, which has wildlife officials scratching their heads a bit. [via]
- I knew about caudal luring — when a predator wiggles uses its tail (usually wiggling it) to attract prey — but this report of Puff Adders (Bitis arietans) using their tongues to do it is something else.
- Painted turtles (Chrysemys) don’t leave the water to hibernate, even when it freezes: they spend the winter under ice. How does that work? How do they breathe? The Nature Conservancy’s Cool Green Science blog explains.
Jean-Claude Savoie, the owner of the African Rock Python that killed two young boys as they slept in August 2013, has been found not guilty of criminal negligence causing death: Canadian Press, CBC News. The verdict comes after an eight-day trial that focused on a ventilation pipe the python escaped through, and whether Savoie was negligent in not securing it, or honestly believed the snake couldn’t squeeze through it.
The trial of Jean-Claude Savoie, the former owner of an African Rock Python that escaped its enclosure and killed two young boys as they slept, begins today. The incident took place in August 2013 and was, to put it mildly, well-reported in the media (I even wrote an op-ed for the Ottawa Citizen about it.) Savoie was subsequently arrested and charged with criminal negligence causing death.
