Teleostei (teleosts) >Pleuronectiformes (Flatfishes) >Pleuronectidae (Righteye flounders) > Hippoglossinae
Etymology:Hippoglossus:Greek, ippos = horse + Greek, glossa = tongue (Ref.45335)stenolepis:From the Greek hippos (horse), glossa (tounge), steno (narrow), lepis, (scale). In 1904, a Russian scientist by the name of P.J. Schmidt first proposed the scientific name based on anatomical differences such as scale shape, pectoral fin length, and body shape which he thought distinguished it from the Atlantic halibut (Hippoglossus hippoglossus). (Ref.94075).

Biology   Glossary (e.g. epibenthic)

Found on various types of bottoms (Ref.2850). Young are found near shore, moving out to deeper waters as they grow older (Ref.6885). Older individuals typically move from deeper water along the edge of the continental shelf where they spend the winter, to shallow coastal water (27-274 m) for the summer (Ref.28499). Feed on fishes, crabs, clams, squids, and other invertebrates (Ref.6885). Utilized fresh, dried or salted, smoked and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref.9988).
