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.
