Q:

Why are crustaceans so well adapted to life on the rocky shore?

Full Answer

The exoskeleton, which is made mostly out of calcium and the protein chitin, offers protection for the crustaceans. However, it also provides lots of support for the attachment of muscles. The crustacean is able to freely move its body with the segmented exoskeleton, which creates joints for ease of movement.
