All icefish are believed to be piscivorous, but can also feed on krill. [10] Icefish are typically ambush predators; thus, they can survive long periods between feeding, and often consume fish up to 50% of their own body length. Maximum body lengths of 25–50 cm (9.8–19.7 in) have been recorded in these species.
Younger icefish tend to eat krill, and then switch to mackerel icefish when they grow (about 30 cm). From data collected in different locations, researchers have determined that the blackfin icefish likely feeds sporadically, consuming large quantities of fish and krill at a time, but at irregular intervals.

Jonah's icefish mainly feeds on fish, such as Dacodraco hunteri, Chaenodraco wilsoni, Pleuragramma antarcticum and Chionodraco sp., as well as krill, as adults. Young specimens, however, feed mainly on krill, especially Euphausia superba , and they are frequently caught along with their prey at 10 to 15 cm (3.9 to 5.9 in) total length.
Cryodraco antarcticus feeds on fishes and krill (studies from 1982 to 1984 revealed mostly fishes and Antarctic krill). The larvae have a long late winter pelagic phase. [1] It is closely related to the blackfin icefish (Chaenocephalus aceratus) but differs in a number of meristic characteristics. They are similar in size, colouration and body ...
Made out of finely ground blanched almonds, this gluten-free flour can be used as a 1:1 swap for all-purpose flour, but the results may vary. With baking (particularly non-yeasted recipes), the ...
Chionodraco hamatus feeds most on small fish, krill, and fish larvae. [7] Spawning appears to occur during the summer and females have a fecundity of 2,900 to 4,200 oocytes. [6] In common with many other channichthyid fishes, reproduction in Chionodraco hamatus involves laying eggs in a nest and parental guarding. Male prepares a nest and ...
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.
Channichthys mithridatis, the green icefish, is a species of marine ray-finned fish belonging to the family Channichthyidae, the crocodile icefishes. It is endemic to the Kerguelen Islands in the Southern Ocean .
