Cutaneous respiration limits the frogs body size. Frogs breath though underdeveloped lungs and their skin. Frogs have loose, mucous lined skin to help them escape from predators, and keep them wet which aides in cutaneous respiration (breathing through the skin). Strong muscles and special fused bones help frogs be powerful swimmers and jumpers. Adult frogs can live on land and in water and are carnivores. Frogs are part of the amphibian order, Anura.
