Biology     Glossary (e.g. epibenthic)

This is found on polychaete tubes and small colonies may be found on other hydroids, Plumularia setacea, Symplectoscyphus sp., Lafoea dumosa and Bougainvillia muscus. It inhabits depths of 5 to 25 m (Ref. 87801). Members of the order Anthoathecata are mostly colonial A-form hydroids. Life cycle: The zygote develops into planula inside the gonophore and is later released as an actinula which metamorphoses into polyp stage (Ref. 833).
