Bry`o*zo"um (?), n. [NL. See Bryozoa.] Zool.

An individual zooid of a bryozoan coralline, of which there may be two or more kinds in a single colony. The zoecia usually have a wreath of tentacles around the mouth, and a well developed stomach and intestinal canal; but these parts are lacking in the other zooids (Avicularia, Oecia, etc.).
