Shore crabs mating

Shore crabs court for a short period before they physically mate. Ocassionally the males fight over the females, this is perhaps why males have larger claws than females. The male carries the female while she is sloughing her shelll. Mating can take place only during a short period after the female has sloughed her shell.
