This is a very normal natural phenomenon. This crab is eating and filtering the organic debris in the sand.

This kind of crab is called window crab. It uses its own pliers to send the organic matter into its mouth, and then discards the sand mass beside it. People need to eat, animals need to eat, and crabs are rubbing dumplings. It looks funny.

This happened in Beihai, Guangxi. A woman traveled to Weizhou Island and wanted to go to the fluorescent sea. As a result, the fluorescent sea didn't see it, but she saw crabs rubbing dumplings.

It is reported that this is a very normal natural phenomenon. After the low tide, crabs rub dumplings on the beach, and they are very skilled. They are small and round, and sand dumplings are made.

At that time, this woman thought it was very funny. It might be a small crab, playing games on the beach, looking particularly cute, and those dumplings were very skillful in making.

Later, she posted this video on the Internet. An insider told this woman that this is a very normal natural phenomenon. This is a crab eating and making sand dumplings with its own pliers. The size of the dumplings is as big as its mouth.

Little crabs eat the organic scraps in the sand, extract the substances they want to get in the sand, and throw away the useless things.

This is a natural phenomenon, but in our human eyes, it is very interesting. This is what different species see. It is estimated that crabs find it very interesting to see some human behaviors. When traveling, try not to pick up these small crabs and touch things around you.

When we are out, some people like to pick up these small shells and crabs on the beach and catch some small fish and shrimps. Personally, I think this is a very bad behavior.

Nature is our common home, which is also the home of human beings, as well as animals and plants. Everyone is in a peaceful place here, and each biological chain has its own survival rules. We should not destroy their survival excessively.

These little crabs are called window crabs. They don't have any meat on them and can be used by us. Therefore, try not to pick up these little crabs, and let them grow freely by themselves at the seaside.

There are some small fish, shrimps, shells and so on. After we take many things home, there is only one ending waiting for them, so we should be friendly to everything.

Natural selection, survival of the fittest, don't use our human ideas to arrange the lives of small animals, only their own lifestyle is the best.

Don't hurt or destroy, give small animals a peaceful living space of their own, just as small animals don't disturb our living space, they should be able to live in harmony with each other.
