A flat encrusting sheet-like colony of tiny individual animals (zooids). Bright red to orange. Colony up to about 2 cm wide.
Madrella sanguinea, a small nudibranch, feeds on these colonies and is often found nearby. 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.
Tidal pools and shallow subtidal waters. commonly attached to algae stems or reef, to depth of 5 m.
