Like most other animals, alligators do have tongues. Their tongues are generally broader than a crocodile’s tongue. Their tongues also help them swallow their prey whole.
Alligators have a U shaped snout. Their upper and lower jaws overlap this snout. The alligator’s lower teeth are mostly hidden when their mouths are closed and fit into sockets located within the upper jaw. Alligators and crocodiles both have salt glands located on their tongues. However the alligator’s salt glands are not functional and their sensory pits are located only near their jaws.
Crocodiles on the other hand have a V shaped snout that is longer. Their upper jaw is about the same size as the lower jaw and their lower teeth are displayed outside the upper jaw when the mouth is closed. Their upper teeth display outside the lower jaw. Their salt glands are located on their tongues and excrete excess salt, their sensory pits are located over most of their bodies.
