Crabs are crustaceans, and we can often see them.One of the important characteristics of crabs is that they can shell.Moreover, they will not only shed their shells once in their lifetime, but will shed their shells a dozen times.If we have been observing crabs, it is very likely that we can observe their shelling phenomenon.Specifically, the crab shelling interval is not necessarily, if the interval is relatively short, then the crab may be able to shell once in about two weeks.If the interval is long, then crabs can only shell once in about two months.
The interval time of crab molting is closely related to the crab's own development and the external environment.If the external environment is more suitable, the crab's own growth and development speed is faster, then the crab shelling interval will be shorter; On the contrary, if the external environment is not suitable, or the crab's own growth and development is not good, it will affect their shelling, the interval will be longer.
The above has been introduced, crabs will molt, and the number of molts in life is more.The main reason why crabs molt is that their shells can't grow.But crabs can not grow in their lifetime, so they can only grow by shelling, in order to overcome this contradiction.The shelling of crabs represents that they are growing, and if crabs want to reach the next stage of their growth state, they must do so by shelling.
