Why are the rainbow strings in the sea or in the river?

Sea Rainbow is often a string of a string, which is in order to fix their own body and take the initiative. The weight of a single rainbow is relatively light, their shell length is only 6-8 cm, and relatively thin, so their body weight will be relatively light, it is easy to be washed away by the current. Therefore, they are generally clustered together in clusters. After gathering up, their weight is relatively heavy and will not be easily washed away by water. This can be regarded as their unique survival skills.

The sea rainbow is a kind of mollusk, and it is quite common in daily life.Rainbow is widely distributed in the ocean, and they can also be cultured artificially.If we can observe them at close range, we will find that they are actually connected in many cases, that is, a string of strings, which is an interesting phenomenon.

In fact, this is a move they take to immobilize their bodies.The body of a certain rainbow is relatively small, their shell is only about 6-8 centimeters, and the shell is relatively thin, their overall weight is relatively light.If they are alone in one place, they will be easily washed away by the current because they are too light.Therefore, generally speaking, they are gathered together and strung together, so that their bodies will be heavier and will not be easily washed away by waves.This phenomenon can actually be regarded as one of Haihong's survival skills.
