CATDOLL : CATDOLL: When do small crabs shed their shells?

Crabs are arthropods, and their shells are their exoskeletons, which protect them and support their bodies. However, they also have a very big disadvantage. Their exoskeleton greatly restricts their growth, so crabs need to shed their shells regularly. Every time they shed their shells, they grow bigger. Because growing a shell consumes a lot of nutrients, and when crabs shed their shells, the new shells are very soft and have no protective effect. This is the most dangerous period for crabs. Crabs will not shed their shells easily unless they have to. Generally, they shed their shells every few months. They will not shed their shells frequently on the first and fifteenth day of the lunar month.
