Brill are flatfish that can camouflage themselves very well by taking on the color or pattern of the surroundings. Because they are practically invisible, they can easily catch passing shrimp and fish from their hiding place. Unlike most other flatfish, brill have both eyes located on the left side of the body. While young brill eat shrimp, older animals switch over to fish: first gobies, later on lesser sandeel, herring and young cod.
