Why can snakes swallow objects much larger than themselves?

As for the phenomenon of "snake swallowing elephant", it is because the angle of the snake's open mouth can reach 130 degrees! And the human mouth can only be opened to 30 degrees. The secret of the snake's ability to open its mouth lies in the unique bone structure of its head.

The jaw bone attached to the snake's head can move, but other animals are immobile, so the snake's mouth can be opened wide. At the same time, the bones between the left and right jaw bones of the snake are also connected by ligaments, so the snake's mouth is actually not limited by movement. a In this way, it is very easy to understand why the snake's mouth can be opened so wide.

However, to swallow large animals, snakes can still be laborious, how does a snake accomplish this stepIt turns out that during swallowing, the snake will "fine-tune" the catch in its mouth, and the animal may be squeezed into a toothpaste shape to fit the snake's body shape. Snakes have hooked teeth in their mouths, and with these teeth, food can easily enter the throat. Since there is no sternum restriction, the snake's ribs can move freely, so food can go directly from the throat into the human stomach, and we can clearly see that the snake's belly is distended.

In addition, snakes are able to produce large amounts of saliva that helps with swallowing, and it acts like lubricating oil. <>

Snakes are able to swallow prey larger than themselves because of their body structure and adaptability. Here are a few main reasons:

1.The body of snakes is very soft and flexible, and can twist and bend their body, allowing them to attack prey that is larger than themselves.

2.The snake has a retractable jaw that allows the snake's jaw to open to the limit to disturb the forest to accommodate prey larger than its own head.

3.The body scales of snakes are very flexible and can bend backwards, allowing the snake to swallow larger prey.

4.The internal organs of snakes are also very soft and retractable, adapting to the shape and size of the body being swallowed.

5.The digestive system of snakes is highly adaptable compared to other animals. Their esophagus, stomach, and intestines are very flexible and are able to expand and contract to accommodate large prey.

The snake's digestive process is also very efficient, and the secretion of digestive enzymes is able to effectively break down the tissues of large prey.

Although snakes are capable of swallowing prey larger than themselves, this does not mean that they can eat at will. Devouring large prey is a complex task for snakes that requires adaptation and training.

Because the snake's mouth can open up to 130 degrees, the reason is that the bones of the snake's head are related to opening and closing.

First of all, its jaw (i.e., the lower jaw) can be opened very much downward, because the snake's head is connected to the lower jaw and several bones are movable, unlike other animals.

Secondly, the bones between the left and right sides of the snake are connected to form a movable tenon (the bones at our human chin do not have a tenon, and the left and right sides become a piece), and the left and right sides are connected by ligaments, which can be opened to both sides, so that the snake's mouth can not only be opened very wide up and down, but also not restricted from left and right, and can expand very large to a certain extent, so that it can swallow things much larger than its mouth.

<> 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 place where the tenon is inlaid by Hara Toshisun, then it can 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 snake's stomach bridge potato chain is not the same as the stomach of chickens and rabbits, it is not spherical, but like a surprisingly long bag.

The snake's intestines are also different from other animals, not twisted and twisted, 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 lot of jokes, the animal's spines and bones pierce the snake's intestines and body walls, causing it great pain.

Snakes are amazing creatures that are able to swallow animals much larger than their own size, a phenomenon that is amazing. Know the lead.

Why, then, is a snake able to swallow an animal larger than itself?

First of all, snakes have a body structure that favors them for devouring large animals.

The body of the snake is made up of many segments, each of which can be moved so that they can twist the large agitator into a smaller shape that is easy to swallow.

In addition, snakes have muscles that can contract so that they can twist large animals into smaller shapes, making them easier to swallow.

Secondly, the mouth structure of snakes also helps them to devour large animals.

The mouth of the snake has a special structure that allows it to twist large animals into smaller shapes, making it easier to swallow.

In addition, the snake's mouth has a special gland that secretes a special fluid that relaxes the muscles of large animals and makes them easier to swallow.

Finally, the digestive system of snakes also helps them to devour large animals.

The snake's digestive system can break down the food of large animals to obtain nutrients.

In addition, the snake's digestive system can also break down the food of large animals into smaller pieces, making it easier to swallow.

In conclusion, snakes are able to swallow animals larger than themselves, mainly because their body structure, mouth structure, and digestive system are conducive to them to swallow large animals.

This ability of snakes is amazing, and it makes my companions appreciate their magic even more.
