In February 2021, scientists discovered and documented a breeding colony of Neopagetopsis ionah icefish estimated to have 60 million active nests across an area of approximately 92 square miles at the bottom of the Weddell Sea in Antarctica. [6] The majority of nests were occupied by one adult fish guarding an average of 1,735 eggs in each nest ...
The blackfin icefish belongs to Notothenioidei, a suborder of fishes that accounts for 90% of the fish fauna on the Antarctic continental shelf. [3] Icefishes, also called white-blooded fishes, are a unique family in that they are the only known vertebrates to lack haemoglobin , making their blood oxygen carrying capacity just 10% that of other ...

Antarctic fish are best known for their uses in studying adaptive radiation, the ecological process that causes the rapid development of several different species from one common ancestor of this fishes. These studies have been done using genetics, phylogeny, study of paleontology, and combinations of these fields to determine the sister ...
Nototheniidae species are largely found in the Southern Ocean and are particularly abundant off the shores of Antarctica. [7] As the dominant Antarctic fish taxa, they occupy both sea-bottom and water-column ecological niches. [8] Nototheniidae is a family of teleost fishes found mainly in the Southern Ocean, surrounding the continent of ...

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.
