Abstract
The Decapoda consists of two taxa, the Dendrobranchiata, which include the penaeoid and sergestoid shrimps, and the Pleocyemata including the caridean shrimp, lobsters, and crabs. Four characters distinguish the Dendrobranchiata: (1) “dendrobranchiate” gill structure, (2) different patterning of the first three pairs of pereopods (walking limbs), (3) lateral flaps (pleura) of the second abdominal somite nonoverlapping with the first somite, and (4) eggs freely spawned versus carried on the abdominal pleopods (Dall et al. 1990). The dendrobranchiate shrimp are of interest both for commercial importance as food and for their significance as a taxon of decapod crustaceans showing many supposedly plesiomorphic characters.
