Most amphibians grow out of their gills before adulthood.
When an amphibian is a larva, it will have gills. As it matures into the adult stage, it will develop lungs.
A amphibian has neither lungs or gills
Amphibian lungs do not have to be as efficient as gills because there is much more oxygen in air than in water.
In the early stages of development, amphibians live in the water they breathe with gills as an adult an amphibian lives on land and uses lungs to breathe.
Frogs and toads have gills as tadpoles, and lungs as adults.
Tadpoles use gills to breath. Adult amphibians breath with their lungs, and frogs can get a little oxygen from their skin, when moist or wet.
They have a larval and adult life, have moist skin, larvae have gills while adults have lungs, and they perform amplexus to mate.

As the amphibian goes from larval to tadpole stage it losses its gills and develops lungs to breathe air and also limbs are formed to walk better on land in case of frogs
