Most frogs (not all), start their lives as tiny tadpoles adapted for a fully aquatic life. Over time, the tadpoles will grow legs, lose their tails, and metamorph into adult frogs. Tadpoles have external gills when they hatch. At about 4 -6 weeks old, the gills are gradually covered by skin, forming an opercular chamber … Read more
