Known from mangroves (Ref. 86642), tidal inlets, exposed areas of bays, including any ledges at their entrance, sounds, caves, shallow coastal benthic habitats (< 25m) and surface or near surface water layers, including porpitids and the halopelagic Sargassum sp. fauna (Ref.86643). Also found in Carrie Bow Cay, Belize, in patch reefs, Thalassia sp. beds, low spur and groove zones, sand trough, outer ridge and fore-reef slopes on algae, Thalassia sp. blades and substrates composed of dead corals and gorgonians at depths of 4 to 18m. As with other hydroids, this species exhibits a pelagic medusoid stage (Ref. 87156).
