Pacific Halibut

Hippoglossus stenolepis

The Pacific halibut (Hippoglossus stenolepis) is one of the largest flatfish in the world, reaching up to 267 cm and over 220 kg. It has a dark brown upper side that matches the ocean floor and a white underside, with both eyes positioned on the right side. Found in the North Pacific from Japan and the Bering Sea to California, it inhabits sandy and gravel bottoms at depths of 0 to 1,200 meters, though most commonly at 100 to 400 meters. This powerful predator feeds on fish, crabs, clams, and octopus. Females grow much larger than males and can live for over 55 years. Encountering a large halibut on a dive is an impressive and somewhat startling experience, as these massive fish can appear suddenly from the substrate when disturbed, their enormous diamond-shaped body creating an unforgettable sight.
