The Atlantic halibut is a right-eyed flounder. It is flattened sideways and habitually lies on the left side of its body with both eyes migrating to the right side of its head during development.  The left side of its body becomes white while the upper side of the fish is a uniformly dark chocolate, olive or slate color, and can be almost black.

This species is sought after for its large size and delicious, firm white flesh, often used in various culinary preparations. Overfishing has historically been a concern, leading to regulations for sustainable fishing.

In summary, the Atlantic Halibut is an ecologically and commercially important species, valued both for its culinary qualities and its role in marine ecosystems. Sustainable fishing practices are crucial for its conservation.
