Top
A suborder of the Isopoda containing aquatic species of considerable morphologic and ecologic diversity. These crustaceans are usually divided into three major groups, the Paraselloidea, Aselloidea, and Stenetrioidea. Asellotes such as Asellus (see illustration) are found in freshwater streams; Caecidotea, in subterranean water; Caeioniropsis, in the interstices of marine sands as commensals with other isopods such as Caecijaera and Jaera and in shallow waters of the seas; and Macrostylus, in the greatest depth of the seas. See also Crustacea; Isopoda.
Asellus communis. (After H. S. Pratt, Manual of the Common Invertebrate Animals, rev. ed., McGraw-Hill, 1951)
