Crocodiles are fierce animals with strong bite force, but why can't they stick out their tongues?

Crocodiles have always been fierce in people's minds. At the same time, because most people can't see real crocodiles in their daily lives, you usually see them in the animal kingdom, so most of us don't know anything about crocodiles. It is rumored that crocodiles have no tongues. In fact, crocodiles have tongues, but when they stick to their chins, they are not easy to be found. When the crocodile pounced on the food, it put its tongue on its throat and poured water. In addition, the crocodile's tongue can secrete excess salt glands in the body.

Crocodiles actually have tongues, but their chins are too long to stick out their tongues. This gives people the illusion that crocodiles can't spit out their tongues, and crocodiles' jaws are biologically evolved. This result is beneficial for crocodiles to suddenly pour water into the water, and large prey enters the water, so these animals suffocate and die. Crocodiles stick their tongues to their chins most of the time, and you don't even dare to open your mouth for us to see. Crocodile is a very famous animal. When looking at their pictures or actually watching them eat, some people think they have no tongue when they see that there seems to be no tongue in their mouths. Well, crocodiles also have tongues, but their tongues are different from those of humans and most familiar animals.

Crocodiles do have tongues, although it is not easy to observe, and tongues also play an important role in life activities. For crocodiles, their tongues are not useless. When the crocodile pounces on its prey, it puts its tongue on its throat to prevent water from flooding into its stomach. In addition, the crocodile's tongue can secrete too many salt glands in the body, so don't say that the crocodile has no tongue, and its tongue is also very practical. The crocodile's tongue sticks to its chin and is not easy to be found. Crocodiles rush forward when hunting, that is, stick their tongues to their throats to keep the water out. In addition, they have salt glands on their tongues, which can secrete excess salt in their bodies.

The crocodile's tongue won't move because the film is caught under its mouth. Because the crocodile has a salt gland on its tongue, its function is mainly to secrete salt like a human kidney. It should be noted that crocodiles have insufficient renal function, thick shells and salt tolerance. So it is difficult to discharge salt from the skin. So crocodiles need to excrete salt with their tongues to avoid dehydration.
