The three are sometimes referred to as the Lophophorata. Bryozoans, or "moss animals," are aquatic organisms, living for the most part in colonies of interconnected individuals. A few to many millions of these individuals may form one colony. Some bryozoans encrust rocky surfaces, shells, or algae.
