Hippoglossus

Hippoglossus is a genus of very large righteye flounders. It comprises two species of halibut, with one species native to the northern Atlantic Ocean and the other species native to the northern Pacific Ocean.

Etymology

The word hippoglossus is derived from the Greek ἵππος, meaning "horse", and γλῶσσα, meaning "tongue" - a reference to the shape of the fish.

There are two species in this genus:

Image	Scientific name	Distribution
	Hippoglossus hippoglossus	northern Atlantic, from Labrador and Greenland to Iceland, the Barents Sea and as far south as the Bay of Biscay and Virginia
	Hippoglossus stenolepis P. J. Schmidt, 1904	Gulf of Alaska and the Bering Sea, off the west coast of Canada, coastal Washington, Oregon, and California

Fossil remains of an indeterminate Hippoglossus are known from the Middle Miocene-aged Agnevo Formation of Sakhalin, Russia.
