Within the crustaceans are several classes, usually characterized by the number of thoracic and abdominal appendages (remember the head appendages are fixed at five for all crustaceans). Crabs belong to a group of animals known as the Crustacea. M. J. Nonnative species cause economic and ecological impacts in habitats they invade, but there is little information on how they spread and become abundant. Another unifying feature of the Malacostraca is that the gonopore (where sperm and eggs are extruded) is always on the base of the sixth thoracic appendage in females and on the eighth in males. … The class Malacostraca, which includes the decapods, nearly always has 19 segments bearing 19 pairs of appendages.
