Chionodraco is a genus of marine ray-finned fish belonging to the family Channichthyidae, the crocodile icefishes.

[2] There are currently three recognized species in this genus:[3] Chionodraco icefishes may have the spine on the snout present or it is reduced to a small centrally placed knob.

[3] Chionodraco contains two circum-antarctic species, one of which is apparently confined to West Antarctica.

[3] Chionodraco icefishes are predatory, feeding on other fish species and krill.

[3] In common with many other channichthyid fishes, reproduction in Chionodraco hamatus involves laying eggs in a nest and parental guarding.
