The fiddler crab or calling crab is any of the hundred species of semiterrestrial marine crabs in the family Ocypodidae. These crabs are well known for their extreme sexual dimorphism, where the male crabs have a major claw significantly larger than their minor claw, whilst females' claws are both the same size. The name fiddler crab comes from the appearance of their small and large claw together, looking similar to a fiddle.
