Metamorphosis in frogs can take from a couple of weeks to a couple of years, depending on the species. The stages progress from larva to polliwog to frog. During this process, gills disappear, lungs appear, the tail disappears, and legs develop. More information about the frog life cycle and metamorphosis:
