How do snakes hear without ears?

Answer:
They don't. They can't really hear so they flick out their tongue to smell.

The above answer is WRONG ! Snakes DO hear. Though they have no external ears, they DO have the remaining components - they pick up vibrations through the ground, which travel along their jaw-bone to the inner ear.
