Crocodiles do have tongues but they are built in a way where they cannot poke them out of their mouths. They can however, still swallow. It is also quite common for crocodiles to allow smaller birds to sit in their mouths to pick their teeth as they cannot maneuver their tongues around. A crocodile’s tongue lies between each mandibular bone of the lower jaw. Although relatively immobile due to its slender and snouted type build, a crocodile’s tongue can be pushed against the roof of the mouth to manipulate objects or pulled down to create a pouch for hatchlings.
Another interesting thing to know about crocodiles is that their tongues are typically colored bright yellow or orange. The tongue’s color may provide a social or warning signal when the croc’s jaws are open. Pores are known to cover the surface of the tongue through which salt glands produce a saline fluid. Their salivary glands purpose is to secrete excess salt from the crocodile’s body. Chemoreceptors lining the tongue help the crocodile to detect food underwater.
