Fun Facts

  • Only the male Fiddler Crabs have one very large claw. Females have two same-sized small claws.
  • Fiddler crabs got their names since the large claw of the male crab makes him look like he’s playing the fiddle, especially when he moves it back and forth.
  • The male’s large claw is used to defend against other fiddler crabs.
  • Male fiddler crabs dig burrows to live in which have “hoods” at the entrance to keep out the rain.
  • The female fiddler crabs pick their male fiddler crab mate by choosing the burrow and rain hood that they like best.
  • If a male fiddler crab loses his large claw, the smaller claw will grow to be the big claw and he will grow a new small claw. This is why you may see fiddler crabs with a right-side large claw or with a left-side large claw.
