Explanation:
Frog undergoes a complete metamorphosis. It includes the egg, tadpole, froglet and then adult frog stages. In complete metamorphosis the hatchling does not resemble the parent and changes as it grows to be an adult.
During metamorphosis the tadpole will develop back legs first, then front legs. Around 6 weeks of life the mouth starts to widen. Sometime around 10 weeks the froglet’s, as it is now called, eyes start to bulge out and the tail begins to shrink and eventually disappear. When the lungs finish developing the froglet makes it’s way onto the land and, Ta-da! It’s a frog!
