Etymology: Notothenia: Greek, 'notos', ou; νοτος, ου), from the south + Greek, 'e 'eutheneia',as or 'euthenia', as (ευθενεια, ας; ευθενια, ας), 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).

Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 4 - 6; Μαλακές ραχιαίες ακτίνες (συνολικά) : 35 - 38; Μαλακές εδρικές ακτίνες: 26 - 30. Wide interorbital space, fewer pectoral rays, lack of scales below the eye (Ref. 11892).
Most commonly found in less than 200 m (Re. 5179). Stomach contents included
mainly small crustaceans (Amphipoda and Euphausiacea) and seaweeds (Ref. 122792).
