Icefish populations are known to reside in the Atlantic and Indian sectors of the Southern Ocean, as well as the continental shelf waters surrounding Antarctica. [3] Water temperatures in these regions remain relatively stable, generally ranging from −1.8 to 2 °C (28.8 to 35.6 °F). [4]
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] The latter is one of eight different families that belong to the suborder Notothenioidei of the order ...
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 ...
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.
Channichthyidae, the crocodile icefish or white-blooded fish of the Antarctic region, so-named for their cold habitat and clear (colorless) blood without hemoglobin Jonah's icefish (Neopagetopsis ionah), of the Southern Ocean; Nototheniidae, the cod icefish or notothens of the Antarctic region, whose members have red, hemoglobin-rich blood
Head of a preserved specimen. Described by Sir John Richardson in 1844 and being the type species of the genus Channichthys, the unicorn icefish is generally pale brown, though smaller specimens have four dark cross-bars present on each side of the body, and dark spots are present on the body, sometimes with reddish patches and dark reticulations are present.
The team also discovered three more new species of snakehead fish: one with red cheeks, another with orange-tipped fins and one with “saddle-like” markings. Winged ‘metallic blue’ creature ...
Around 98% of continental Antarctica is covered in ice up to 4.7 kilometres (2.9 mi) thick. [1] Antarctica's icy deserts have extremely low temperatures, high solar radiation, and extreme dryness. [2] Any precipitation that does fall usually falls as snow, and is restricted to a band around 300 kilometres (186 mi) from the coast.
