The presence of embryos is detected due to their orange color, and was only recorded in April. C. pallasiana occurs most commonly between April and December, with colonies active at all times during this period. C. pallasiana occurred on nearly any hard substratum including rock, glass, and beach rocks. 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.
