Frogs go through a lifecycle, which means their stages are constantly changing and starting over. The first stage of the lifecycle begins with the eggs. A frog lays many eggs are one time. The eggs are covered in a jellylike coating. This coating is used to protect it from the weather and other animals. The second stage is the tadpole. Once the eggs hatch, these tadpoles have gills for breathing in water. They have a tail, but no legs! The third stage is the froglet. As it changes from a tadpole to a froglet, lungs begin to grow. Back and front legs begin to grow. These parts allow the adult frog to live on land. The final stage is adult frog. Once the lungs begin to work, the gills and tail disappear. The adult frog is now ready to live on land. For the cycle to begin again, the adult frog lays eggs.
