Frog
Frogs are animals that can live on land and in water. Young frogs live in water and breathe with gills. Adult frogs live on land and breathe using the lungs.
When the adult frog will lay eggs, the frog will go to the water to remove the eggs. Frogs have always wet skin to help their breathing because this always wet skin contains lots of blood vessels so it can help oxygen diffuse through its skin.
