(From Wikipedia) Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen), usually hidden entirely under the thorax (brachyura means "short tail" in Greek).

FACT: Many aquatic arthropods have undergone carcinization, where their body becomes stout and their tail reduced like true crabs!
