The Snake In The Garden Of Eden With A Squirrel

Gopher Snake

Evolution is truly fascinating. There’s a video of a squirrel tap dancing around a snake and bravely nibbling on its body. The quality isn’t that great, so the identity of the snake is a bit of a mystery. It acts like a rattlesnake, but it doesn’t have the arrow shaped head, which is characteristic of the viper family. However, non-venomous gopher snakes mimic the behavior of rattlers to scare away predators. And on top of that, even if it were a rattlesnake, the squirrel has a genetic advantage. Adult squirrels have a partial immunity to rattlesnake venom. They can take several hits of venom and still survive. They even have a physiological mechanism to heat up their tails, which fools with the snake’s heat sensing ability. The moral of the story is that our human preconceptions about what’s going on in the natural world are often wrong.
