Aselloidea |
Asellota is a suborder of isopod crustaceans found in marine and freshwater environments.[2] Roughly one-quarter of all marine isopods belong to this suborder.[3] 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 (a character shared with some other isopod groups), the fusion of pleonites 5, 4 and sometimes 3 to the pleotelson, and absence of the first pleopod in females.[3][4]
The suborder Asellota comprises these families:[5] Some classifications also include the Microcerberidea within Asellota.[5]
