Prawns are crustaceans, belonging to the sub-order Dendrobranchiata [1]. They are similar in appearance to shrimp, but can be distinguished by the gill structure which is branching in prawns (hence the name, dendro=“tree”; branchia=“gill”), but is lamellar in shrimp. The sister taxon to Dendrobranchiata is Pleocyemata, which contains all the true shrimp, crabs, lobsters, etc.
