How do snakes swallow when they eat?

When a snake eats, it doesn't bite down slowly, but swallows the whole thing in a way of "swallowing dates". Although snakes have no limbs to help them hunt, they have serrated teeth with dense barbs, so once they catch food, they will hook it with their teeth and swallow it directly into their stomachs. If you catch a big food that is difficult to swallow directly, you will quickly wrap it around the upper body several times, and the more you wrap it, the tighter it will be. When it completely suffocates and dies, it will be squeezed and thinned, and then it will be eaten slowly. This is the method used by pythons to swallow big food. When poisonous snakes prey, they usually take the method of sudden attack. First, they bite animals fiercely, inject venom into the captured animals, bite for a while and then swallow them. But sometimes the animals are thrown away first, and after a few minutes, the animals are poisoned or die, and then they are swallowed leisurely. When swallowing food, most snakes instinctively look for the head of their prey and start swallowing from the head, but there are also cases where they start swallowing from the bite, such as the tiger-spotted snake and the red chain snake.
