That seems like its for a lizard of some kind. my crabs have no scales and they are fully aquatic.

lol I'm sorry I didn't read right through it!
Your right! lol It is about lizards but titled crabs! my ooops!
Check out this link.The male crabs have one large claw and the females have two smaller claws the same size.
The larger claw is used in mating rituals.
