We are blessed with an abundance of flora and fauna in Georgian Bay and one very interesting group is frogs. For tens of millions of years amphibians and the ancestors of frogs were the dominant land animals. Amphibians are vertebrates with permeable, non-scaly skin and aquatic larvae that metamorphose into adult form. Some of these ancient creatures achieved crocodile-like sizes and terrorized swampy ecosystems as the top predators. An ancient vertebrate lineage, frogs are the only land animals to lead two totally different lives: one underwater with a body plan to match and a second life with four legs on land.
