Notothenia rossii


Notothenia is a genus of cod icefishes, ray-finned fish in the family Nototheniidae. They inhabit the cold Southern Ocean and other waters around Antarctica. These fish have some adaptations that allow them to thrive in such inhospitable habitat, like antifreeze proteins in their blood and ample fat to insulate them against heat loss and to offset their lack of a swim bladder.


Many listings only feature 5 species: N. neglecta is often considered conspecific with N. coriiceps, while the little-known N. trigramma is of doubtful validity. Other species formerly placed herein are now in related genera like Lepidonotothen.
