Biology     Glossary (e.g. epibenthic)

Height is based on colonies (Ref. 3248) Distributed world-wide in warm seas (Ref. 3248). Known from tidal inlets, exposed areas of bays, including any ledges at their entrance, sounds, caves, shallow reefs and shallow coastal benthic habitats (< 25 m) (Ref. 86643). Also found in Carrie Bow Cay, Belize, in patch reefs, high and low spur and groove zones, sand trough, outer ridge and fore-reef slopes on substrates composed of dead corals and gorgonians at depths of 2 to 18 m. As with other hydroids, this species exhibits a pelagic medusiod stage (Ref. 87156). Species exhibits both asexual and sexual reproduction by budding during hydroid stage and release of gametes in medusae stages (Ref. 1663, p. 15, 18). Period of reproductive maturity recorded for Carrie Bow Cay, Belize is from 17th April to 21st June, during which the samples collected had gonophores or medusa buds (Ref. 87156).
