When the tides get low, you can see Fiddler Crabs swarming the little ponds at the salt marshes on Cape Cod. I was walking home the other day when I saw hundreds of  Fiddler Crabs coming out of their little holes in the salt marsh.

“Fiddler crabs are found along sea beaches and brackish inter-tidal mud flats, lagoons and swamps. Fiddler crabs are most well known for their sexually dimorphic claws; the males’ major claw is much larger than the minor claw while the females’ claws are both the same size.

Like all crabs, fiddler crabs shed their shells as they grow. If they have lost legs or claws during their present growth cycle, a new one will be present when they molt.”
