The crocodile icefish or white-blooded fish comprise a family ( Channichthyidae) of notothenioid fish found in the Southern Ocean around Antarctica. They are the only known vertebrates to lack hemoglobin in their blood as adults. [2] Icefish populations are known to reside in the Atlantic and Indian sectors of the Southern Ocean, as well as the ...
Blackfin icefish. The blackfin icefish ( Chaenocephalus aceratus ), also known as the Scotia Sea icefish, is a species of crocodile icefish belonging to the family Channichthyidae. [2] The blackfin icefish belongs to Notothenioidei, a suborder of fishes that accounts for 90% of the fish fauna on the Antarctic continental shelf. [3]
The ocellated icefish (Chionodraco rastrospinosus) is a fish of the family Channichthyidae. It lives in the cold waters off Antarctica and is known for having transparent haemoglobin-free blood. 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.
Cryodraco antarcticus, the long-fingered icefish, is a demersal species of marine ray-finned fish belonging to the family Channichthyidae, the crocodile icefishes. It occurs only in deep waters of the Southern Ocean .
Channichthys was first formally described as a genus in 1844 by the Scottish naval surgeon, naturalist and Arctic explorer John Richardson when he described the unicorn icefish ( Channichthys rhinoceratus) which he placed in a new monotypic genus. [1] Subsequently up to nine species have been classified within Channichthys which is what ...

There are relatively few families in this region, the most species-rich being the Liparidae (snailfishes), followed by Nototheniidae (cod icefishes). [1] The latter is one of eight different families that belong to the suborder ...
Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
