Seagrasses as well as floating macroalgae, provide support for bryozoan colonies. In turn, bryozoans provide habitat for many species of juvenile fishes and their invertebrate prey such as polychaete worms, amphipods and copepods. (Winston 1995).Bryozoans are also found in association with other species that act as support structures: mangrove roots, oyster beds, mussels, etc.
