Snakes Hear With Jaws

We know that snakes see heat with their noses and smell with their tongues. Now, we know they hear with their jaws.

Snakes only have an inner ear system. The cochlea - instrumental in hearing - is connected to the snake's jawbone. Vibrations that move a snake's jaw, therefore, allow the snake to hear ... even as minute as that of a rodent. Because snakes can unhinge their jaws one side at a time, they may be able to hear in stereo.
