| Abstract |
Shrimps are long-tailed crustaceans closely related to other familiar animals such as crayfishes, lobsters, and crabs. They are important food items which support major fishery and aquaculture industries around the world. Shrimps are also termed “prawns,” but the usage of these terms varies regionally around the world. Shrimps exemplify the “caridoid facies,” the primitive shrimplike body form in the Class Malacostraca. Although shrimps are basically pelagic and epibenthic swimming animals characterized by the backward escape respond (tail flip), modification of the caridoid facies has allowed invasion of benthic habitats as well. Shrimps are important ecological and food web components of both freshwater and marine habitats. The major decapod shrimp taxa (~4400 species) are the Dendrobranchiata (sergestoids and penaeoids), the Caridea, and the Stenopodidea. The Caridea are the most diverse taxonomically and ecologically, while the dendrobranchiates are the most productive in fisheries and aquaculture. Penaeoids and sergestoids have three pairs of small chelae, dendrobranchiate gills, and each abdominal pleura (side plates) overlaps the one just posterior. Carideans usually have two, never three, pairs of chelae, phyllobranchiate gills and the second abdominal pleuron is saddle-shaped, overlapping the first and third pleura. Stenopodideans have three pairs of chelae, but the third is much larger and weapon-like than the first two. They have trichobranchiate gills and little overlap of abdominal pleura. |
