The Arrow Crab, also known as the Spider Crab, has extremely long legs. It is called the Arrow Crab because of the shape of the body and head. The size is variable, many reaching six inches, and some up to 10 inches. Females may be dramatically smaller. It is a hardy, long-lived invertebrate, that can be housed in the reef aquarium. This crab has been known to attack crustaceans such as Banded Coral Shrimp, and may even attack small slow moving fish. All crabs are opportunistic feeders and if insufficient food is present they may pick at mushrooms or polyps searching for food. However, Arrow Crabs may provide the beneficial service of eating smaller Bristle Worms which some consider pests.
