What do you mean by crocodile tears? Why are they called crocodile tears?

This language refers to false tears and sympathy in disguise. It is an ancient western legend to call false tears "crocodile tears". It is said that fierce and cruel crocodiles shed sad tears when they eat their prey.

In fact, crocodiles are not sad at all, just lubricating their eyes. When the crocodile dives into the water, the blink film in the crocodile's eyes is closed, which can not only see the underwater situation clearly, but also protect the eyes; When the crocodile is on land, the instant film is used to moisten the eyes, which needs tears to lubricate.

Extended data

Crocodile eyes are as mysterious as tears. Careful people will find that the crocodile's eyes suddenly grow above the head and take a non-disturbing poaching method.

Crocodiles often lurk underwater, visiting prey on the water. Once they find the target, they dive into the water without disturbing the prey on the water. Just as they approached their prey, they rushed up in lightning speed to catch their prey and have a good meal. Crocodiles have prominent eyes, and the advantage is that they just adapt to the function of crocodiles peeping at water prey from the bottom of the water.

Based on this, scientists concluded that after a long evolution, ancient crocodiles slowly moved their eyes above their heads and evolved into modern crocodiles with poaching skills.
