Greenland halibut are a large flatfish that have both eyes on the right side of their head. Their close relatives, the Atlantic halibut and Pacific halibut, use this design to swim flat against the ocean floor, as do Greenland halibut. However, Greenland halibut are also known to swim vertically, thanks to their eyes being closer to the front of their head than their relatives, allowing them to look forward while swimming upright. Greenland halibut use this ability to swim vertically to help them migrate and forage for food.
