The Chionodraco hamatus is a fish in the family Channichthyidae, the "crocodile icefish".

Description

Specimens range from 33 to 37 cm, with a maximum length of 49 cm.[2]

Distribution

Chionodraco hamatus is found in the cold waters of the continental shelf surrounding Antarctica.[2]

Habitat

This species lives in the demersal zone, and can be found at a depth range of 4 to 400 metres.[2]

Diet

Chionodraco hamatus feeds most on small fish, krill, and fish larvae. [3]

Reproduction

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 courts the female. Egg deposition (and presumably fertilization too) takes place at night. Female remains in the nest, guarding and fanning the eggs. Hatching takes place over a prolonged period of time. Male seems not to be involved in the care of the eggs.[4]
