  Bryozoum \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 zo[oe]cia
     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, O[oe]cia,
     etc.).
