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 inhabit. 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. Preyed upon by sea slugs and
grazing fishes. |
