Some people living in the crocodile-infested area occasionally find that the crocodile will have some very strange behavior, for example, the crocodile will swallow some rocks, and even the crocodiles living in the swamp area of the river beach can run far in order to swallow the stones Distance to find.
At this time, many people will have doubts, why should crocodiles eat stones? Is there any specific help for crocodiles?
In fact, according to scientific research, crocodiles swallow stones not because they are hungry and have nothing to eat, but to help the crocodiles digest. Crocodiles have no teeth to chew on, and every bite is a big bite, which is very bad for their digestion. So what should I do? The friction between stones can only be used to help the stomach digest by swallowing stones.
At the same time, the crocodile swallowing the stones helps the crocodile to increase the gravity of its body and plays a very important role. For example, the crocodile diving time can be extended to prevent it from being washed away by the turbulent current. Secondly, increasing the weight of the crocodile also helps to improve the crocodile’s killing of prey and increases the possibility that the crocodile will pull the prey into the water.
