In honor of World Snake Day, which is today, here's what happens when you put a bunch of snakes on a plane...for science.
Most animals perceive the weightlessness of microgravity as if they were falling upside down. If you drop a cat from a great height, for example, it will roll over to attempt to land on its feet. This is called the "righting response." In microgravity, this leads to repeated rolling-over.
Scientists have interpreted the repeated rolling-over as a repetitive righting response, since the animal never gets any feedback that the action was successfully executed. This behavioral pattern is common and has been observed for various mammals, frogs, and turtles in microgravity.
