occurs on old bivalve shells buried at one to two centimetres in the sandy seabed on open sandy to silty seabed in shallow water with mild current flow. It is anchored to shells by a hydrorhiza comprising a short, sticky stolon coated with sand grains. The stolon often passes underneath the shell fragment to more securely anchor the hydrocaulus to the substrate. Most hydrocauli are solitary and widely scattered across the seabed although small patches of up to 10 hydranths rarely occur (

The developing gonophore contains many small eggs, but at maturity only one becomes an actinula. The large apical flanges surmounting the gonophore while rather variable in shape are typically lobate to ear-shaped. The peripheral band of large stenoteles bordering the flange is visible in living material even at low magnification. At release, most actinulae immediately settle on adjacent shell fragments and within a few hours develop a short hydrocaulus; exceptionally, juveniles sometimes attach to an adult stem, giving an appearance of a falsely branched hydrocaulus.</paragraph>
