How is the vision of a flounder structured?

The vision of a flounder, also known as a flatfish, is unique compared to other fish. Flounders have both eyes on one side of their body, which allows them to lie flat on the ocean floor and blend in with their surroundings. This adaptation is known as "ocular migration" or "ocular translocation".

Flounders start their lives with eyes on both sides of their head, like most fish. However, as they grow, one eye migrates to the other side of their body, so both eyes end up on the same side. The side with the eyes is usually the upper side of the fish, while the lower side is typically pale and lacks eyes.

The migration of the eye is a complex process that involves the rotation of the eye socket and the repositioning of the optic nerve. The eye that migrates becomes the dominant eye, while the other eye becomes less functional and may even degenerate over time.

This unique arrangement of the eyes allows flounders to have binocular vision, meaning they can use both eyes together to perceive depth and accurately judge distances. It also enables them to have a wide field of view, as their eyes are positioned on the same side of their body.

Flounders have adapted to their one-sided vision by developing a behavior called "side-swimming." They swim on their sides, with one eye facing upward to scan the water column for prey or predators. This swimming style allows them to maintain a clear line of sight with their dominant eye while remaining camouflaged on the ocean floor.

In conclusion, the vision of a flounder is structured in a unique way compared to other fish. Their eyes migrate to one side of their body, providing them with binocular vision and a wide field of view. This adaptation allows flounders to effectively navigate their environment and hunt for prey while remaining hidden on the ocean floor.
