The crocodile says “cry” while eating its prey. But in fact, no tears come from his eyes. According to some studies, the crocodile has sweat glands on its head. And they decrease while eating. In this way, the animal’s body gets rid of the liquid containing harmful salts. According to Swedish scientists, this is because crocodile kidneys do not work very efficiently.
In addition, the salt expelled by the crocodile’s “tears” harms reptiles and benefits insects. This liquid contains mineral salts.
This feature is also found in other animals. For example turtles, some lizards and snakes.
