Halibut is the largest flat fish in the world

Halibut are gray-black on the top side with an off-white underbelly, with very small scales, invisible to the naked eye, embedded in their skin. When they are born, they have an eye on either side of their head and swim like a salmon. However, after 6 months, one eye migrates to the other side, thus making them look more like flounder. At the same time the stationary-eyed side darkens to match the top side, while the other side remains white. This colour scheme disguises halibut from above (blending in with the ocean floor) and from below (blending into the light from the sky). This is known as countershading. Halibut diet on almost any animal they can fit into their mouth.
