A saltwater fish characterized by having both eyes on the left side of its body. It has a light brown body with several pairs of large dark brown spots and countless small white spots, giving it a protective coloration that blends in with the sand. The fins also have dark brown spots. It has a larger mouth than the flatfish. Swim by swinging your body. Pretty early.
It inhabits sand and mud and looks up with both eyes. It preys on small bottom-dwelling fish and crustaceans. They come to shallow waters to spawn in the summer and move to deeper waters in the winter.
I found it in the sandy area between the reefs in the morning. It has a color that blends in with the sand, but its distinctive silhouette makes it easy to find. It floated a little and swam with its body fluttering.

It was swimming with its fins flapping.
