Hemilepidotus, the Irish lords, is a genus of ray-finned fishes and the only member of the family Hemilepidotidae.23 These fishes are found in the northern Pacific Ocean and adjacent regions of the Arctic Ocean.4
They were previously placed as the subfamily Hemilepidotinae in the family Agonidae, the poachers and sea ravens.2 However, a 2026 study found it to form a distinct clade with Nautichthys and Hemitripteridae, and morphologically distinct enough to deserve its own family.5
Species
There are currently six recognized species in this genus:46
