Sand Sole is a flatfish scientifically known as Psettichthys melanostictus. It is found in the sea bottom of sands in the northeastern Pacific waters.
The fish can be seen in many colours such as green, gray, brown, black with a white color in the ventral side.
The one things which makes this fish unique is its eyes. When a Sand sole fish is born, its eyes are on both sides just like other fishes but as these grow to mature, the eyes migrate to either left or right.
Since the fish do not migrate too much to the other areas and likes to lay on the sea bed; both the eyes remains looking upward.
