These reef-dwelling fish are great at camouflage, using their mottled coloring and texture to sneak up on smaller fish and crustaceans and swallow them whole in one fast gulp. From short face and big eyes, to stout caudal (tail) fin, they are usually seven to 14 inches long, and are named for the colorful markings on their pectoral fins, including a dark area with white spots. Because there are venomous spines in their dorsal fins, caution should be used if handling these fish, or when diving in rocky reef areas.
