Recorded distribution in Britain and IrelandHistorically found throughout British and Irish waters although the current distribution is relatively unknown.
HabitatHippoglossus hippoglossus is a predominantly benthic and demersal species or more infrequently pelagic. They are usually found on sand, gravel, or clay substrates and not on soft mud or on a rocky seabed.
- Large, right-eyed flatfish up to 2.5 m in length.
- Uniform dark brown to dark olive colouring on the upper surface, often paler and more mottled in younger fish.
- Continuous dorsal fin which has longer rays in the centre.
- The rear edge of its tail fin is concave, not rounded.
- The two ventral fins are alike.
- The lateral line is strongly curved above the pectoral fin unlike Reinhardtius hippoglossoides.
Additional informationAtlantic halibut feed mainly on other fish (cod, haddock, pogge, sand-eels, herring, capelin) but also targets cephalopods, large crustaceans and other bottom-living animals. Due to slow growth rates and late onset of sexual maturity, Hippoglossus hippoglossus populations can be seriously affected by overfishing (Muus & Nielsen, 1999).
