The scorpion fishes and sculpins is a large group of mostly marine fish that are found throughout the world. There are more than 1320 species in 35 families, the majority of those families are found only in the world's oceans. Scorpion fishes and sculpins are generally squat fish that live at or near the bottom of bodies of water and are not strong swimmers, although some are streamlined and live in the main water column. Scorpion fishes and sculpins are mainly predators, but eat a wide variety of foods.
