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).
Eponymy: Rear-Admiral Sir James Clark Ross (1800–1862) discovered the Ross Sea and the Ross Ice Shelf and an island (1841) which Scott, on his first expedition, named Ross Island in his honour. [...] (Ref. 128868), visit book page.

The sexually immature members of the population stay in lesser depths, mainly in the shallow fjord bays. Yearlings feed mainly on mesozooplankton in the near surface zone (5-15 m). Immature and mature fish are benthic but stay in shallower depths (10-20 m). Sexually mature fish move out of the fjord to stay in the shelf zone. Spawn once a year (Ref. 89316). Maximum life span for males is 12 years (Ref. 28106).
Mature females may spawn for the first time from around 6-8 years of age (Ref. 71843).
