Calappa species "have evolved structures that are specifically designed to deal with the more common dextral snails - they have essentially become right-handed. This asymmetry has evolved convergently in at least two groups of crabs, a Cretaceous crab known as Megaxantho and the extant box crabs (Calappa). Here, one of the claws is enlarged and operates with a scissor-like action that facilitates peeling open the snail."[Wikipedia]

Governor's Reef off Seven Mile Beach. As they often do, this crab repeatedly buried into the sand so I could not photograph it in situ. Thus, I was forced to hold it in my hand to get a shot. Another name for these crabs is "box crab".
