In the spring many frogs lay their eggs in ponds that dry up in the summer What advantages does metamorphosis provide in such a situation?

All of our amphibians lay their eggs in water. Most frogs, toads and salamanders like to lay their eggs in small ponds where there are no fish to eat the eggs or young. If the young amphibians grow and change to adult shape quickly, the eggs can be laid in ponds that dry up by late summer. So some amphibians breed in ponds that fill with water from melting snow in spring or heavy rains in summer. They can live in places where there are no ponds or other water for part of the year.
