W. subovoidea is one of the most abundant bryozoan species in the IRL and along the coast of Florida. It is also among the most common fouling organisms in this area. It is present year-round, but is most abundant in the winter months. Its success as a fouling organism is attributed to its rapid growth rate and its ability to grow on nearly every hard substratum including those coated with copper antifouling paint (Wisely 1958 in Winston 1982). W. subovoidea is most abundant on the rocks of breakwaters at or near the mean low water level.Locomotion: Sessile
