Most amphibians lay their eggs in water. Frogs' eggs are called spawn. They are protected from predators by a thick layer of jelly. Inside a tadpole develops. When it hatches out, it is able to swim, using its long tail, and breatheats through gills. As a tadpold grows, first hind legs and then fore legs begin to grow. Lungs develop, and the young frog is able to begin to breathe wiuh its head above water. Gradually the tail shortens until the young frog resembles its adult parents.
