Earthworms breathe through their moist skin. Amphibians like frogs breathe on land using their lungs and in water, they breathe through their skin. Gaseous exchange through the skin is known as cutaneous respiration. All animals with cutaneous respiration have moist and slimy skin which allows gases to easily pass through by diffusion. Birds breathe through their lungs while insects like cockroaches breathe through tiny pores on their body called spiracles.
