Most frogs and toads undergo holometabolism: frog larvae, called tadpoles (or pollywogs), hatch from their eggs and change into adult frogs, which look and act differently. Tadpoles have gills and fins and completely live, breathe, and eat in water. Adult frogs have lungs and legs and live, breath, and eat out of water.
