[3] Notothenia angustata is a large demersal fish which is quite similar in shape and colour to the Maori cod (Paranotothen magellanica).

The colour is dark grey or green on the upper body with blue-black mottling and it has a yellow abdomen.

[4] Notothenia angustata feeds on cephalopods, benthic invertrebrates and small fishes.

[5] This species has some of the same genes as its more southerly relatives for the production of antifreeze proteins in its blood.

[6] The Chilean study referenced above found 11 taxa of parasites living in specimens of this species including digeneans, cestodes and nematodes.
