Which type of fish has both eyes on the same side of its body? Answer
The type of fish that has both eyes on the same side of its body is a flatfish, a category that includes well-known species like flounder, halibut, and sole. This striking and defining characteristic is not present from birth but is the result of a remarkable biological transformation that occurs during the fish’s development.
When a flatfish first hatches from its egg, it swims upright in the water column like any other fish, with one eye positioned on each side of its head. As it begins to mature, however, a process of metamorphosis takes place. Over the course of several weeks, one of its eyes slowly migrates from its original position, traveling across the top of the fish’s head until it comes to rest alongside the other eye on the opposite side. At the same time, the fish’s skull twists and its body flattens out to prepare it for life as a bottom dweller.
