Lizard Tongue

You may have noticed that many lizards flick their tongues out of their mouths. Why do they do this? Simply put, they are smelling. When they flick their tongues out, small amounts of a materials 'scent' sticks to it, and then it is brought into their mouths. Lizards have an organ called the Jacobson's organ, that helps to process the scent. The tissue of the organ 'absorbs' the scent, allowing the lizard to perceive the substance. Think about how a dog sniffs a lot when they are excited about food, for example.

After a lizard finishes eating, they will lick their lips to clean them. Most lizards use their tongue to drink as well, lapping up water drops, or even from a dish. Lizard tongues differ in shape and size, depending on the species.

Chameleon Tongues

The tongue of a chameleon is highly specialized, and are commonly called a 'ballistic' tongue. They are most often longer than the chameleons body, and can be shot out of their mouths at high speeds to snare their prey. The tongue itself is composed of muscle, bone, and tendon. The club-like tip of the chameleon tongue is covered is thick mucus, which sticks to the prey, and allows the chameleon to draw the tongue, with prey attached, back into their mouths for eating.

Gecko Tongues

Geckos clean their eyes with their tongues, due to the fact that they lack eyelids.
