Etymology: Notothenia: Greek, 'notos', ou; ?????, ??), from the south + Greek, 'e 'eutheneia',as or 'euthenia', as (????????, ??; ???????, ??), abundance (P. Romero, pers.comm. 01/16); coriiceps: coriiceps from Latin corium skin or leather plus ceps head = skin head or leather head (Ref. 11892). More on author: Richardson.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 0 - 550 m. Polar; 46°S - 78°S, 180°W - 180°E
Southern Ocean: probably circum-Antarctic on the continental shelf. So far, known from the western Ross Sea, Balleny islands, Adélie Land, Antarctic Peninsula and associated islands, islands of the Scotia Arc to South Georgia, Weddell Sea, Bouvet, and the sub-Antarctic islands of the Indian Ocean sector.
