Psychrolutes is a genus of marine ray-finned fishes belonging to the family Psychrolutidae, the fatheads and toadfishes. Though found predominantly in the deep sea, a handful of species are present in the intertidal regions of the North Pacific rim. In June 2003, During the NORFANZ Expedition north-west of New Zealand, scientists trawled a specimen of P. microporos at a depth between and on the Norfolk Ridge.
