Did you know: A Crocodile Cannot Stick its Tongue out?

crocodile-mouth4The crocodile’s tongue is attached to the bottom of its mouth by a membrane.

A crocodile may not be able to stick out its tongue at you, but it isn’t entirely useless.

The crocodile’s tongue has salt glands which means that a crocodile’s tongue performs the same function for a crocodile that kidneys perform for us: excreting salt.

Crocodiles have less efficient kidneys and have thick, salt-resistant skin, which means that they have a hard time releasing salt through their skin. They have to use their tongue to get rid of salt and keep from getting dehydrated.
