Atlantic halibut are native to the North Atlantic Ocean, ranging from Virginia to Greenland in the western Atlantic and from the Bay of Biscay to the Barents Sea in the eastern Atlantic. They inhabit cold, deep marine waters along the continental shelf, typically over sandy, gravel, or muddy bottoms. Atlantic halibut feed on fish such as cod and herring, as well as squid and crustaceans. They are the largest flatfish species, commonly reaching 1.5–2.5 meters (5–8 feet) in length and weighing several hundred kilograms. Key identifiers include their large, flattened body with both eyes on the right side, dark brown upper surface, white underside, and slightly concave tail. An interesting fact is that Atlantic halibut are slow-growing and long-lived, making them vulnerable to overfishing. Anglers catch them using heavy bottom gear with large baited hooks or jigs in deep water.
