Class Malacostraca

14 (rarely 15) body segments (torax (pereon) of 8 segments and abdomen (pleon) of 6 (rarely 7) segments). The head bears 5 pairs of appendages. Each thoracic segment bears a pair of appendages, basically biramous but variously modifed, with a gill developed at the base of each appendage. Each abdominal segment is similarly equipped with a pair of biramous appendages. The last pair of abdominal appendages is often broadened, and with the last abdominal segment, the telson, constitutes a tail fan. (Hayward, Ryland, 1990)

Decapoda

Order Decapoda

First 3 pairs of toracopods transformed to maxillipeds. First pair of pereopods usually bears chelaes. Gills are usually enclosed by carapace' folds. One pair of uropods is expanded and together with telson form caudal fin. (Jashnov, 1948)

Phylum:Arthropoda

The malacostracan body plan comprises a, primitively, five-segmented head, often fused with the thorax, or pereon, of eight segments; the abdomen, or pleon, consists of a further six segments, or rarely seven. The head bears two pairs of antennae, usually well-developed, the first pair of which is typically biramous; there are two pairs of maxillae and up to three pairs of maxillipeds; compound eyes are usually present, often stalked, but may be absent. Each thoracic segment bears a pair of appendages, basically biramous but variously modifed, with a gill developed at the base of each appendage; the first three pairs are employed in feeding, while the rest are variously modified forming the locomotory pereopods. Each abdominal segment is similarly equipped with a pair of biramous appendages, the pleopods and uropods, modified for swimming or reproduction, or both functions, and occasionally for respiratory purposes. The last pair of abdominal appendages is often broadened, and with the last abdominal segment, the telson, constitutes a tail fan. (Hayward, Ryland, 1990)
