Antarctic fish is a common name for a variety of fish that inhabit the Southern Ocean. There are relatively few families in this region, the most species-rich being the Liparidae (snailfishes), followed by Nototheniidae (cod icefishes). [ 1 ]
Antarctica, including the subantarctic islands, has no natural fully terrestrial mammals, reptiles, or amphibians. Human activity has however led to the introduction in some areas of foreign species, such as rats, mice, chickens, rabbits, cats, pigs, sheep, cattle, reindeer, and various fish. [13]

The Antarctic toothfish (Dissostichus mawsoni), also known as the Antarctic cod, is a large, black or brown fish found in very cold (subzero) waters of the Southern Ocean near Antarctica. It is the largest fish in the Southern Ocean, feeding on shrimp and smaller fish, and preyed on by whales, orcas, and seals.
The group is found mainly in Antarctic and Subantarctic waters, with some species ranging north to southern Australia and southern South America. [2] [3] Notothenioids constitute approximately 90% of the fish biomass in the continental shelf waters surrounding Antarctica. [4]
The ocellated icefish (Chionodraco rastrospinosus) is a fish of the family Channichthyidae. [3] [4] It lives in the cold waters off Antarctica and is known for having transparent haemoglobin-free blood. [5] [6] C. rastrospinosus live in the Southern Ocean up to a depth of 1 km. They are most commonly found on the seabed at 200–400 m.
Small fish primarily feed on copepods, euphausiid larvae, and hyperiids. [3] This species is mainly the nektonic prey species of seabirds in open water. [4] It is an important krill predator and serves as prey for a majority of seabirds. [5] It is one of the southernmost fish species, being recorded as far south as 74°40′S in the Ross Sea. [6]
