When observing crocodiles, it is not easy for us to observe their tongues. Even when they are feeding, the tongue is not very obvious. However, we can not think that crocodiles do not have tongues, at this time crocodiles have tongues, but it is not easy to find them. Crocodile tongue also has an important role in their life activities can play a very important role.
For example, when they open their mouths in the water, their tongues can be pressed against their throats to prevent them from being poured into their bodies. Because crocodiles breathe with their lungs, if water is poured into their lungs in large quantities, it may lead to drowning of crocodiles, which may also pose a threat to their lives, so the tongue structure is indispensable. In addition, crocodiles need to excrete some excess salt from their bodies, but they can not rely on kidneys and sweat glands to excrete salt as humans do. In fact, the crocodile's tongue also plays a part in excreting salt. When they come ashore, they may open their mouths, which is to drain salt.
As mentioned above, the crocodile has a tongue, but it is not easy to find it. Their tongues are different from most animals, because their tongues are very inconspicuous close to their jaws. When they open their mouths, the tongue lifts to some extent, but it's not easy to see, just like it touches the roof of the mouth. However, it can not be mistaken that crocodiles do not have tongues, in fact, they have tongues, and the role of tongues is very important.
