Height is based on colonies (Ref. 3248). Maximum depth from Ref. 116013. 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, shallow coastal benthic habitats (< 25 m) (Ref. 86643), and on mangrove roots (Ref. 121478). 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 medusoid stage (Ref. 87156).

Life cycle and mating behavior Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | Larvae

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).
