The crocodile is a very famous animal. When looking at pictures of them, or actually watching them eat, some people will find that crocodiles do not seem to have tongues in their mouths, so they will think that crocodiles do not have tongues. In fact, crocodiles also have tongues, but their tongues are different from those of humans and most of the animals we are familiar with.
When crocodiles are not eating, their tongues are attached to their jaws. When crocodiles eat, their tongues will have a certain degree of bulge, but it is not easy to find, so if not carefully observed, it is like crocodiles do not have tongues. Although the crocodile's tongue is not easy to observe, crocodiles have tongues, and their tongues play an important role in their life activities.
As mentioned above, crocodiles have tongues, but they are not easy to find because they are close to their jaws. The crocodile's tongue plays an important role. When crocodiles hunt in the water, they sometimes suddenly rush forward with their mouths open. At this time, the tongue plays a role in holding the throat, which can prevent a large amount of water from pouring into the crocodile's body from the throat and prevent the crocodile from drowning. If there is no tongue, it is easy for crocodiles to pour a lot of water into their lungs when they hunt, which is harmful to their bodies.
In addition, the crocodile's tongue also has the function of excreting salt. Crocodiles have excess salt to excrete, but their kidneys are not very developed, and they can not excrete salt through sweat glands like humans. Their tongue plays a very important role in salt excretion, thus regulating the balance of water and salt in the body. When the crocodile comes ashore, it opens its mouth and expels the excess salt. In addition to the tongue, crocodiles also excrete salt through tears.
