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

[4] The name Pagetodes was applied to a fish which was washed onto the bow of HMS Terror and frozen in place.

[5] In 1844 John Richardson described the genus Pagetodes from Robertson’s drawing in volume 2 of Ichthyology of the voyage of H. M. S. Erebus & Terror.

However, the status of C. pappenheimi is less clear; the holotype was deposited in the Natural History Museum, Berlin and has been lost.

They are predatory and analyses of stomach contents have shown they feed on fishes and krill.
