Epizoa

Epizoa, a subdivision of the Crustacea once accepted for the three sessile and degraded orders, the Cirripedia, Ichthyophthira, and Rhizocephala.

The group is, however, now abandoned, and included in the sub-class Entomostraca (q.v.), as the Rhizocephala are regarded as degraded Cirripedia and the Ichthyophthira as parasitic Copepods.
