Crocodiles eat stones for two main reasons. The first reason is that crocodiles do not have teeth that can be used to chew, and they eat with a large bite, and the stomach of crocodiles is soft, and it is difficult to digest food after entering the stomach, so they can only swallow stones and use the friction between stones to help the stomach digest. The second reason is that crocodiles can help crocodiles improve their body's gravity by eating stones, prolong the crocodile's diving time, and improve the crocodile's prey.

Crocodiles use the stones in their stomachs to grind the bones and hard shells of their prey, helping to grind their food and acting as a "storehouse". These rocks make it easier for the crocodile to lurk and move underwater, not being swept away by the strong currents, and also help the crocodile to drag large prey into the water.
Some people who have studied crocodiles have found that crocodiles devour stones. Crocodiles that live in areas with a lot of silt and little soil sometimes have to crawl farther away in search of rocks in search of them.
Scientists have observed that young crocodiles without stones in their stomachs are much inferior in their diving ability to those who have swallowed stones. According to research, crocodiles 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 strong currents, and also help the crocodile to drag large prey into the water.
Do you know? Crocodile eggs are not divided into male and female when they are first born, and the crocodile sex will only be separated when the crocodile eggs hatch, and the sex of the crocodile is still determined by temperature. When the crocodile's nest temperature is 32 to 36, a male crocodile will hatch.
When this temperature is above or below this, a female crocodile hatches. And when the temperature from the top to the bottom of the nest is different, crocodiles of both sexes hatch.

The crocodile's stomach is soft, and it uses stones to grind the bones and hard objects in its food. The weight of the stone swallowed by a crocodile is about 1% of its body weight.

Because the crocodile's teeth can only bite the pieces of meat, they cannot chew the pieces of meat, and can only rely on stones to grind the bones and hard objects of the food. Because the crocodile's stomach is so soft, even the fragile shell of a water snail cannot be destroyed without stones.
Observations have shown that young crocodiles, which do not have stones in their stomachs, are much inferior in diving ability to their peers who have swallowed stones. Based on this, scientists believe that the stones not only help the crocodile grind food, but also serve as a "storen".
This "barn" makes it easier for crocodiles to lurk and move underwater, without being swept away by the turbulent currents. In addition, the stones also help the crocodile to drag large prey into the water.

Ant Manor QuestionWhy crocodiles love to eat stones, let's take a look at how to choose the right answer.
Answer: Aids digestion and weight gain
Answer analysis: Crocodiles do not have teeth that can be used to chew, so they can only swallow stones, using the friction between stones to help the stomach digest. By eating stones, crocodiles help crocodiles improve their body's gravity, prolong crocodile diving time, and improve crocodiles' prey hunting.
-
In addition, the crocodile can also make its body thicker by eating stones, which makes it easier for the crocodile to sink to the bottom, which can better allow the crocodile to move underwater, so as not to be washed away by the turbulent river, and it is more convenient for the crocodile to drag some large prey into the water.

The reasons why crocodiles burn fish and eat rocks are as follows:
1. The crocodile does not have teeth that can be used to chew, and the stomach of the crocodile is soft, and it is difficult to digest the food after entering the stomach, so it can only swallow the stone and use the friction between the stones to help the stomach digest.
2. Crocodiles eat stones over the years, which is conducive to helping crocodiles improve their body's gravity, prolong the time of crocodile diving, and improve the prey hunting of crocodiles in Xiaozhou.

Hello. On the one hand, the crocodile eats stones as the "blender" of the crocodile's stomach, and the crocodile's teeth do not have the function of chewing, and the large pieces of meat are not easy for Huai to digest, so they have to eat some stone reeds to grind the bones and hard shells of the prey, so as to help digestion. On the other hand, the underwater "town" stone can play the role of a "town", and the stone can make the crocodile lurk well underwater.
When a crocodile bites a person, it will not let go, it will drag the person into the water, and it will want to swallow the person in the stomach; To be bitten by a crocodile is to feel waiting and being swallowed.
I'm sure many people think that the earth was ruled by reptiles before the extinction of the dinosaurs, but in fact, such a statement can be said to be incorrect. To be precise, after the Carboniferous, two major groups of amniotic animals diverged, one of which was the conglocutary group (inferior pore), which included modern mammals and their ancestors, and the other was a group of sauriformes (saurophores) that included birds, dinosaurs, crocodiles, lizards, etc., and their ancestors, and for a long time, the one that evolved into modern reptiles, that is, the latter, was not dominant. All of the Permian, half of the Triassic, terrestrial vertebrates consist mainly of the ancestors of living mammals, the Zygosaurus, including the creeping but sail-like Coilosaurs, and the theropores more closely to mammals. >>>More

Crocodiles have had two experiences of entering land, one was after the Permian mass extinction, when the crocodiles began to develop and the Lloyd's crocodile appeared. They have long legs that can run, and even have longer hind limbs than forelimbs, and have the ability to run bipedally, similar to early dinosaurs, which were supposed to be on their diet. However, the mass extinction at the end of the Triassic allowed the dinosaurs to overtake them, and the crocodiles were beaten back into their form in the water. >>>More
