Although eating yourself is a very weird thing, this kind of animal still barely exists in nature. Some animals fell into a hunter's trap and had to bite off one of their own legs in order to escape. Although they were forced to do so, they could barely be considered as eating themselves; some snakes can't help but eat when they are very hungry. Its own tail, or the snake may mistake its tail for another animal; some animals will eat their own cells after giving birth. Carnivores

In order to capture wild animals, hunters often place powerful traps in the forest, which can sometimes trap predators such as tigers, wolves, leopards, and bears. But these animals were not stupid either. They knew that they had no chance of survival this time, so they imitated the technique used by human warriors to break off their wrists and bit off one of their trapped legs. This should be considered eating oneself, but their behavior is to save themselves, and they do not really want to harm themselves. Losing a leg is better than losing one's life. Snakes

Snakes are mysterious animals in the eyes of many people, and they do have many puzzling animal behaviors. For example, some zoologists have discovered that snakes will eat their own tails, which means that snakes will swallow their own tails, and then continue to eat their own bodies. In the end, they will suffocate to death when they can no longer swallow. This situation may occur because the snake is really too hungry, or it may be that the snake is greedy, or the snake is temporarily insane and mistook its tail for another small animal, so it swallows the tail, eventually causing itself to suffocate to death. Many people probably wouldn’t have thought that such a day would happen to the insidious and poisonous snakes. This situation was called the cycle of life in ancient Greece, which means that the cycle of life is endless and never stops. Mammals

Among mammals, there is also the phenomenon of eating certain parts of their own bodies. This is mainly because some animals eat their own cells after giving birth, either for pain relief or to supplement nutrition. For example, domestic cats have this behavior. If you have a female cat at home, you can observe this situation.
