The Pacific halibut, or Hippoglossus stenolepis [from the Greek hippos (horse), glossa (tongue), steno (narrow), lepis (scale)], is one of the largest species of teleosts. Its scientific name was first proposed in 1904 by P.J. Schmidt, a Russian scientist who noted anatomical differences such as scale shape, pectoral fin length, and body shape which Schmidt thought distinguished it from the Atlantic halibut (Hippoglossus hippoglossus).
