Found in patch reefs and sand trough areas on substrates composed of dead corals and gorgonians. In Belize, it is found at depths of 5-17 m. As with other hydroids, this species exhibits a pelagic medusoid stage (Ref. 813).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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.
