ResumoAbstract An annotated list of deep-sea Anthozoa of the orders Actiniaria, Antipatharia, Scleractinia, Alcyonacea and Pennatulacea collected on the G.O. Sars MAR-ECO cruise to the Mid-Atlantic Ridge between the Azores and the southern tip of the Reykjanes Ridge is given. A total of 33 species is reported of which 32 were identified to species or genus level. The groups most rich in species were Actiniaria (nine species), Scleractinia (eight species) and Pennatulacea (eight species). Scleractinia, Antipatharia and Pennatulacea were mainly represented by species with a wide or cosmopolitan geographical distribution. In contrast, most of the actiniarians had been rarely recorded in the North Atlantic. Three species, Schizopathes affinis Brook, 1889 (Antipatharia), Dendrobrachia multispina Opresko & Bayer, 1991 and Heteropolypus cf. insolitus Tixier-Durivault, 1964 (Alcyonacea) are reported from the North Atlantic for the first time.
