Because it can be collected in the IRL year round, A. leucocypha is considered to be eurythermal . A. leucocypha typically encrusts gastropod shells. Unilaminar colonies are generally found on living gastropods, while multilaminar colonies are often found on dead gastropod shells inhabited by hermit crabs. 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.
Bryozoans are ecologically important in the Indian River Lagoon due to their feeding method.
As suspension feeders, they act as living filters in the marine environment.
