Spotted the worlds prettiest garter snake while herping. Love how his body kinda makes an infinity symbol with the way he moves. Took a few quick photos and left him to his snakey business
Garter snakes make friends, organize their society around females
Finding comes from first-of-its-kind study of thousands of wild snakes
Garter snakes have something in common with elephants, orcas, and naked mole rats: They form social groups that center around females. The snakes have clear “communities” composed of individuals they prefer hanging out with, and females act as leaders that tie the groups together and guide their members’ movements, according to the most extensive field study of snake sociality ever carried out.
“This is an important first step in understanding how a community of snakes is organized in the wild,” says Gordon Burghardt, an ecologist at the University of Tennessee, Knoxville, who was not involved in the research. Other experts agree: “This is a big deal,” says integrative biologist Robert Mason of Oregon State University. “It’s a whole new avenue of research that I don’t think people have really given any thought to.”
Ecologists had long assumed snakes are antisocial loners that hang out together only for core functions such as mating and hibernation. However, in 2020, Morgan Skinner, a behavioral ecologist at Wilfrid Laurier University, and collaborators showed in laboratory experiments that captive garter snakes have “friends”—specific snakes whose company they prefer over others. Still, studies of wild snakes were lacking “because they’re so secretive and difficult to find,” Skinner says...
I was so, so lucky to meet a very special trio of snakes for a class I'm taking on methods in field ecology. One of my two professors is a specialist in garter snakes and was kind enough to bring three different species in for us to compare in person and observe up close. The first was the gorgeous common garter snake, Thamnophis sirtalis, pictures above. She was so calm and well-mannered!
Next was this tiny (by comparison) T. elegans dude, a western garter snake, who was wary of the camera but very patient about being passed around by a group of excited college students. He matched my classmate's sweater perfectly!
Finally, an endangered and incredibly precious T. gigas, the giant garter snake. She's about half of her maximum adult size, so a giant indeed! She musked and peed a bit but for the most part this gojira-faced beauty was pretty chill. We got to observe a full work-up for her including documenting records and microchipping.
She's one of the last of her species. Despite Herculean efforts by her protectors and conservation experts (mostly just one man and his dedicated team), this is a very difficult species to observe in the wild and their habitats are disappearing faster than their need for prioritization of protection in a given area can be assessed. These snakes rely on riparian habitat near rivers, which is also unfortunately a favorite for human development. At this time we don't know how exactly many giant garter snakes are left or whether their current populations are stable.
Today we got to visit their marshland habitat and watch these three go back to the place where they were caught. It was a huge honor and something I'll carry with me forever.
They are so common in our local habitat that we almost stepped on it. This one is like 20 inches and can grow up to 50 inches in length. A good thing their saliva is not dangerous at all for humans but to amphibians and other small animals, it's quite toxic.
