Description

Scott's notothen is a small notothenioid fish of the family Nototheniidae from the cold waters of the Southern Ocean around Antarctica. The species grows to about 16 cm and has a stocky, mottled body with a large head. It lives demersally on the continental shelf and slope. As a bottom searcher it feeds mainly on polychaete worms, krill (euphausiids) and amphipods. Like other notothenioids it is adapted to the ice-cold water around freezing point. The species is a link in the Antarctic food web and is harmless to humans.
