Etymology: Notothenia: Greek, 'notos', ou; ?????, ??), from the south + Greek, 'e 'eutheneia',as or 'euthenia', as (????????, ??; ???????, ??), 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 / climate zone / depth range / distribution range
Marine; benthopelagic; depth range 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.
Length at first maturity / Size / Weight / Age
Maturity: Lm 30.0  range ? - ? cm
Max length : 45.0 cm SL male/unsexed; (Ref. 11892)
Morphology | Morphometrics
(total): 3 - 7;
soft rays: 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.
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).
