Nototheniidae

In some scientific literature, the term "cod icefish" is used to identify members of this family. This should not be confused with the term "icefish," which refers to the "white-blooded" fishes of the family Channichthyidae. See Icefish (other).

Nototheniidae, the notothens or cod icefishes, is a family of ray-finned fishes, part of the suborderNotothenioidei which is traditionally placed within the orderPerciformes. They are largely found in the Southern Ocean.
