A sedentary colonial aquatic animal found chiefly in the sea, either encrusting rocks, seaweeds, or other surfaces, or forming stalked fronds. Each minute zooid filter-feeds by means of a crown of ciliated tentacles (lophophore). Also called bryozoan, polyzoan, ectoproct.
- Phylum Bryozoa (or Polyzoa, Ectoprocta).
- Bryozoans, or ‘moss animals,’ are aquatic, mostly marine, colonial organisms, superficially rather like coral.
- A little deeper than 10m, velvety mounds of soft coral, sponges, tunicates and moss animals are densely packed together.
- Similar to sponges, but with tentacles, moss animals or bryozoans are strange creatures.
