C. seurati and C. tenuissimum co-occur in estuarine habitats, but their reproductive seasons are apparently offset. However, throughout January, settlement rates between both species tend to equalize, and by May, only C. seurati is still settling. After fertilization, embryos develop into planktonic larvae. C. seurati , like all bryozoans, is a suspension feeder . 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.
