It is collected year-round in the IRL, but colonies may overwinter in a dormant state. S. aegyptiacum , like all bryozoans, is a suspension feeder . S. aegyptiacum is typically found entangled among hydroid stems, primarily Thyrosccyphus and Eudendrium species. It has also been documented to colonize both benthic and floating algae, and may utilize other substrata such as shell fragments and beach rock. Seagrasses as well as floating macroalgae , provide support for bryozoan colonies.
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.
