Why can a snake swallow an animal several times larger than itself? This is because they have a special set of structures in their bodies. Our human mouth can only be opened at an angle of 30 degrees, but the mouth of a snake can be opened to an angle of 130 degrees, or even 180 degrees.
The reason for this is that the bones of our mouths are connected by "tenons", but snakes are connected to each other by ligaments. Here, we might as well do an experiment: the tongs used by people when cooking rice are not easy to open because they are inlaid with tenons; If you divide the tongs into two and tie a rubber band to the original tenon, it will open freely.
The snake's mouth can be opened very wide, and this is also true. Moreover, the serpent has processed the animal before devouring the large animal: when it wraps around its prey, it tightens as it wraps until it suffocates to death; It then squeezes its prey into long strips for easy swallowing.
What if the snake catches a bird with wings like two folding fans? When a small belly snake devours a larger bird, it usually always swallows the bird's head first. In order to prevent the bird from slipping out of the mouth, the pit viper's left and right rows of teeth alternately do a series of slow motions
The left tooth does not move, firmly hooking the bird, and the right tooth slowly moves forward, pulling the prey into the mouth; Then the right tooth hooks the food, and the left tooth moves forward ......In this way, it slowly devoured, and the pair of open wings of the bird also converged in one direction. When a snake swallows a large animal, will the trachea be blocked? No, it won't.
Because the opening of the larynx is in front of the floor of the mouth, which is also where the opening of the trachea is. When a snake devours its prey, its movable larynx extends out of its mouth so that it does not have to worry about its trachea being blocked. Will large animals pass through the intestines of snakes unimpeded?
Yes. You know, the stomach of a snake is not the same as that of a chicken or a rabbit, it is not spherical, but resembles a surprisingly long bag. The snake's intestines are also different from other animals, not crooked, but a straight pipe.
A straight bowel is great for swallowing larger foods. Of course, then again, snakes don't always have to eat large animals easily, and sometimes they come at a great cost. People sometimes see that when snakes swallow large animals, the food is stuck in the mouth, and they can't spit it out, and they can't swallow it when they want to; Or get a mouth full of blood, and the teeth are broken.
Sometimes, although the snake swallows a large animal, the animal's spines and bones pierce the snake's intestines and body walls, causing it great pain.

It's true, the python's eyes have a great stretching function, and when it eats a behemoth many times larger than him, its pharyngeal bones will be misaligned, but he himself will soon be reset.

Snakes are able to swallow animals that are more than ten times larger than themselves because they have bones related to opening and closing their heads. First of all, its jaw (i.e., the lower jaw) can be opened very much downwards because the few bones of the snake's head connected to the jaw are movable, unlike other animals. Secondly, the bone between the left and right chin of the snake is connected into a movable tenon (the bone in our human jaw does not have a tenon, the left and right are a piece), and the left and right sides are connected by ligaments, which can be expanded to both sides.
So, the snake's mouth is horribly large, and it's not limited to the left and right, and it can spread very large to a certain extent, so that it can swallow something much bigger than its mouth. At the same time, snakes also secrete a large amount of saliva, which acts as a "lubricating oil" to help swallow.
Although the snake cannot swallow an elephant, it can swallow an animal much larger than its own head. Experts who have visited Snake Island have seen pit vipers devour birds that are more than ten times larger than its head. Even a normal snake can devour a rat larger than its head.
There have been many cases of snakes eating too much food and being strangled to death, this is a Burmese python swallowing a crocodile, but the crocodile is too large, and eventually the python is broken by the crocodile and dies.
When swallowing, the snake first opens its mouth wide, holds the animal's head into its mouth, clamps the animal's body with its teeth, and then swallows slowly with the mandible. When one mandible is turned backwards, the ipsilateral tooth hooks the food and sends it further to the pharynx, followed by the other mandible turning backwards, and the ipsilateral tooth sends food further to the pharynx. In this way, even large foods can be swallowed due to the constant interaction of the mandible turning backwards.

For example, a very thin snake can eat a fat mouse.

Generally, several bones of the lower jaw of a snake are separated, so the snake's mouth can be opened up to 130 degrees, or even 180 degrees
-
The mouth can only be opened up to 30 degrees, but the snake can open up to 130 degrees! The reason is that the bones of snakes' heads are different from those of other animals.
