The stems are tubular, with a yellowish coloured tegument and are branched at the base. The polyp colour is pale pink through to red, and consists of a central circlet of oral tentacles surrounded by paler but larger aboral tentacles[4]

Ectopleura larynx is usually found on rocks or attached to algae.[5] It is most common in shallow water, fouling piers and on the undersides of boats; in the British Isles, seas surrounding Great Britain, and the Americas. E. larynx grows in colonies and can tolerate exposed habitats and strong water currents.[6]
