Atlantic Halibut
Hippoglossus hippoglossus
Sighting evidence at Agdenes Lighthouse Reef, Trondheim Fjord
Juvenile Atlantic halibut, the world's largest flatfish, are occasionally encountered resting on the sand and gravel flats adjacent to the Agdenes reef, particularly in autumn when cold-water upwelling brings nutrient pulses inshore. Adults can exceed 3 m and 300 kg, and their mottled brown camouflage makes them virtually invisible against the seabed. Norway hosts one of the few remaining viable wild Atlantic halibut populations in the Northeast Atlantic.
