Description

The Antarctic silverfish is a notothenioid fish of the family Nototheniidae and the only truly pelagic species of that family; it is endemic to the Southern Ocean around Antarctica. The species grows to about 25 cm and has a slender, silvery body. It lives in schools in open water and, like other icefishes, possesses antifreeze glycoproteins in its blood that let it survive in below-freezing water. As a plankton feeder it feeds on krill and other zooplankton. The Antarctic silverfish is a central link in the Southern Ocean food web and a main prey for penguins, seals and whales. It is harmless to humans.
