An elongated, spiral-looking colony of tiny individual animals (zooids).
Bryozoan colonies like this species feed using a circlet of tentacles (lophophore) which filters the water. Most bryozoans are hermaphrodites, either containing separate female and male zooids in the colony, or containing both sexes within the one zooid. Colonies can grow quickly and thus some species can be a pest if they foul hulls of ships or the wooden structures of piers.
Usually anchored to structures, including attached to seagrass.
