Question

What do crabs do as soon as they get their new skeleton

Answer 1

Answer:

Explanation:

A new exoskeleton is produced beneath the old one. As the old one is shed, the new skeleton is soft and pliable. The animal will pump itself up to expand the new shell to maximal size, then let it harden. When the shell has set, the empty space inside the new skeleton can be filled up as the animal eats.
