Short description Μορφολογία

Large colonies, as tall as 30 cm, with dark brown to black perisac. Polyp is white with a reddish tinge and has a circle of 10 to 18 filiform tentacles at the base and up to 12 capitate tentacles on the upper part of hydranth.

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).
