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); neglecta: Named after Dr. Nybelin's feeling that this divergent form of coriiceps has been overlooked (Ref. 11892).
Environment: milieu / Klimaatzone / Diepte / distribution range
Ecologie
marien benthopelagisch; diepte 1 - 95 m (Ref. 11892), usually 1 - 90 m (Ref. 11892). Polar
Southern Ocean: coast of the Antarctic continent, Antarctic Peninsula, South Georgia, South Shetland, South Orkney Islands and Peter I Island.
Lengte bij maturiteit / Grootte / Gewicht / Leeftijd
Maturiteit: Lm 30.0 range ? - ? cm
Max length : 45.0 cm SL mannelijk / geslacht onbekend; (Ref. 11892)
Dorsale stekels (totaal) : 3 - 7; Dorsale zachte stralen (totaal) : 37 - 40; Anale stekels: 0; Anale zachte stralen: 27 - 32. Caudal fin subtruncate or slightly rounded, emarginate in young. Coloration more spectacular compared to other nototheniids. Juveniles with a black blotch on distal end of pectoral fin.
Body shape (shape guide): fusiform / normal.
Juveniles found in 1-10 m depth and possibly having a pelagic habit, adults in deeper water (Ref. 11892). Adults feed on crustaceans and fishes (Ref. 11892). Spawn once a year (Ref. 57661). Some information needs to be transferred from N. coriiceps to this species (RF).
Mature females may spawn for the first time from around 6-8 years of age (Ref. 71843).
