Asellota
Asellota is a suborder of isopod crustaceans found in marine and freshwater environments. Roughly one-quarter of all marine isopods belong to this suborder. Members of this suborder are readily distinguished from other isopods by their complex copulatory apparatus. Other characteristics include six-jointed antennal peduncle, the styliform uropods, the fusion of pleonites 5, 4 and sometimes 3 to the pleotelson, and absence of the first pleopod in females.
