Crocodiles are very ferocious animals. However, in the process of observing them, humans have discovered a very strange phenomenon, that is, crocodiles shed tears when hunting for food. The act of shedding tears does not seem to be in line with the fierce character of crocodiles, so people will regard this act as a symbol of crocodile hypocrisy, and compare hypocritical people with crocodile tears. In fact, this is a misunderstanding of crocodiles, crocodiles tears are only physiological reactions, their tears do not have any specific emotions, nor is it hypocritical performance. In fact, they not only shed tears when they hunt, but also when they eat.
As mentioned above, crocodiles shed tears when hunting and eating. This behavior is not a manifestation of crocodile hypocrisy as some people understand. It is simply a physiological phenomenon that is beyond the control of crocodiles, and it does not include the specific emotions of crocodiles. Crocodiles shed tears in order to expel excess salt from their bodies, thus maintaining the balance of water and salt in their bodies and avoiding problems in their bodies. Humans can excrete salt through their kidneys and sweat glands, but crocodiles can't, their kidneys are not very developed, and they can't excrete salt through sweat glands.
The crocodile's main salt drainage measure is through tears. Next to their eyes, there is a structure called a salt gland, which is connected to the blood by many thin tubes and carries the salt from the blood to the body. In human eyes, it seems that crocodiles are crying, but in fact, it is only a measure of crocodiles'salt drainage. In addition to tears, their tongues can also expel some salt.
