If a fiddler loses a claw, they will regrow a new one. If a male loses its big claw, the small claw will grow to become the big claw. Many lose legs, for the same reasons they lose claws. The good news is that crab legs regenerate in the same fashion as claws, forming as limb buds just prior to a molting cycle.
