4. Snakes Smell Using Their Tongues

A snake will use their forked tongue to collect the smell of molecules. It’s forked so they can get a 3D smell in all directions. A snake will know in which direction the prey is just be sticking out its tongue. The tongue is wired straight into Jacobson’s organ, which is attached to the brain.

5. Some Snakes Still have Part Of Their Legs Left

The oldest snake species still have a part of history left on their bodies, such as the boas and the pythons. Left behind are called spurs. They look like claws on the underneath of a snake’s belly. This is because snakes, once upon a time, had legs.

7. Snakes Sleep With Their Eyes Open

9. A Jaw Of A Snake Is Not Locked

For snakes to swallow prey in one go as they do, they need to be able to stretch the jaw since they dont chew or have hands. The jaw of a snake is not attached by bone; a stretchy ligament attaches it. These ligaments can stretch to enormous lengths as and when needed.
