Our fiddler crab is made of plastic and measures 2 1/4 inches from side to side and 2 inches from front to back. This plastic crustacean is one of our series of lively and lifelike plastic animals. Its realistic shape and details will be enjoyed as part of a school project, diorama, plastic animal collection, as a party favor, or gift. Our fiddler crab toy is for decoration or play only. It does not float, and should NOT be put in your aquarium. However, you can make an interesting sea-life or aquarium shoebox diorama using this and other plastic aquatic creatures and mammals, sharks, fish, sea turtles, birds, and decor from our gift shop. There is no mess, no feeding, and no tank cleaning :) Check out our terrific selection of crab toys and gifts.
About Fiddler Crabs Although there are over 50 crab families and 1000s of species, all crabs have basically the same body plan: four pairs of walking legs and one pair of claws (also called nippers or pincers). Their shell is actually their skeleton, called an exoskeleton, and protects their thorax, gills and the internal organs of the head. Like the octopus and sea star, if a crab loses a limb it will regenerate (grow back). The term "fiddler crab" describes any of approximately 100 species of crab of the genus Uca. Fiddler crabs are characterized by their mismatched claws. The little claw is used for feeding, the motion giving it the appearance of playing a fiddle (the large claw). If a fiddler loses the large claw, the small claw will grow to take its place and the lost claw will regenerate into a new small claw. Fiddler crabs are small, the largest being just over 2 inches across.
