What does a crocodile put a stone in its mouth for? Is it to supplement trace elements?

Introduction: Crocodiles stuff stones into their mouths in order to use the stones in their stomachs to grind the bones and hard shells of their prey, which not only helps to grind food, but also acts as a "storen". These rocks make it easier for the crocodile to lurk and move underwater, not being swept away by the turbulent currents, and also help the crocodile use its own weight to drag large prey into the water.

The reason why the crocodile will put the stone in its mouth or eat it in the stomach is mainly to consume the remains of some prey in its stomach, because when the crocodile eats the prey, their way to eat is to swallow the prey alive in the stomach, or wet into several large pieces and swallow it into the stomach, then it is extremely burdensome for his future, and the crocodile will eat ten pieces into the stomach. In order to increase the peristalsis between the intestines and the stones, the stones will dance together when they are not flowing, and the stones will be used to consume the carcasses of these animals to achieve the effect of fast digestion. <>

At the same time, crocodiles often live under the water, if they encounter the flow of unity, then the crocodile is easy to be washed away, when the crocodile adds ten pieces to its body, the weight of the crocodile in the water will rise significantly, then even if there is a united current, it is extremely difficult to wash away the crocodile, and at the same time, it is also conducive to the crocodile to move forward in deep water, because the crocodile itself is in a relatively empty state, and there is more air in the stomach and body, if you don't swallow the block, Then it is almost difficult to move forward in deep water. Therefore, crocodiles will usually eat some large rocks to increase their weight. <>

At the same time, when the crocodile increases its weight to a certain extent, it is also conducive to their better predation, because the crocodile often needs to rely on its own gravity and bite force to drag the prey into the water when hunting, either with its own bite force to bite the prey to death, or to use the water to suffocate the prey, if their weight is too light, the prey will easily drag themselves ashore, thus causing harm to themselves, so the crocodile will take the way of eating heavy stones to increase its weight, In order to achieve the effect of dragging the prey into the water and drowning.

In fact, it is for teeth glossing, not to supplement trace elements, because crocodiles often eat some meat, and some shredded meat will remain in the teeth.

In order to promote their own digestion, but also to promote the peristalsis of the stomach and intestines, in order to prevent the appearance of constipation, will do this behavior. Not only to supplement trace elements, but also to promote gastrointestinal digestion.

It's just to be able to promote vomiting, because the crocodile may be stuck, after all, it eats some large meat. Not in the supplement of trace elements.
