Dense aggregations of antipatharian corals have been discovered by means of remotely operated vehicle (ROV) photo-imaging off the western Pontine Islands (Central-Tyrrhenian Sea, Italy). These black coral assemblages are mainly composed of Parantipathes larix and Leiopathes glaberrima . This discovery constitutes an update of their habitat distribution for the Mediterranean Sea and is relevant for the development of focused protection measures for the study area.
