Amphibians hatch from eggs laid in the water and they pass through a distinctive tadpole/larval stage. The larvae of most species are aquatic and possess gills and prominent fins. Frog and toad tadpoles graze on algae and small organisms in the water; larval salamanders and newts are carnivorous and feed on aquatic insects. During metamorphosis, they acquire legs and lungs. Significant changes in the digestive system coincide with changes in feeding behaviour.

As tadpoles transform into frogs, their tails slowly disappear. During this time, the tadpoles' mouth is changing so they can't eat when they leave the water so they absorb their own tails and use the energy to grow into adult frogs!
