Edriophthalmata

Edriophthalmata (Gr., 'sessile-eyed'), a section of higher crustaceans, including the simpler and more primitive forms, in which the eyes are sessile, not stalked. The title includes the Amphipods (e.g. sandhopper), the Isopods (e.g. woodlouse), and is equivalent to Arthrostraca. See CRUSTACEA.
