Prior to Winston's 1982 study, this species had not been reported in the western hemisphere. Its range now includes estuarine habitats on Florida's east coast. Individual zooids measure an average of 0.55 X 0.33 mm in size. Lophophore diameter measures 0.621 on average. No ovicells are present in this species and eggs are not brooded.
Reproduction is accomplished by releasing eggs into the water column for fertilization.
Peak reproductive season occurs from late winter to early spring. 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 .
