Etymology: Trematomus: Greek, trematos = hole + Greek, tomo = section, cut (Ref. 45335); bernacchii: Species name bernacchii honors Louis Bernarcchi, an Australian physicist-meteorologist; specimen collected on the Southern Cross Expedition and served on Scott's 1901 expedition (Ref. 45168).
Eponymy: Louis Charles ‘Bunny’ Bernacchi (1876–1942) was a physicist and astronomer who took part in several expeditions to Antarctica. [...] (Ref. 128868), visit book page.

背棘 (總數) : 4 - 6; 背的軟條 (總數) : 34 - 39; 臀鰭軟條: 31 - 35. Body brownish, large dark spots in two or three series on body. Spinous dorsal blackish in upper part (Ref. 11892).
Body shape (shape guide): fusiform / normal.

Found in seafloors, well adapted to extremely low and stable temperatures (-1.86°C), annual mean temperature of McMurdo Sound) (Ref. 45168). Feed on polychaetes, gastropods, isopods, amphipods and few algae. Spawn once a year (Ref. 1071). Utilized for human consumption. The report by Ref. 4537 as commercially important is probably a mistake for Trematomus eulepidotus (SAU, NB303).
