Phylum Bryozoa

Moss Animals or Bryozoans

Bryozoans are minute colonial animals that feed by filtering plankton from seawater.  They have a fleshy or rigid calcified structure in which the individual zooids live.  Unlike corals the bryozoan animal has a separate mouth & anus and the zooid's 'box' has a lid for protection.  Many bryozoans are members of the fouling community in bays and harbors and have been dispersed throughout the world on the bottom of ships.  Hawaii has many introduced and native species.  Positive identification of many species is only possible after microscopic examination.  Preyed upon by sea slugs and grazing fishes.
