Frogs begin their lives as tiny tadpoles living in water. As adults, they live both on land and in the water. The Life Cycle of a Frog details the changes in a frog at the four stages: egg, tadpole, froglet, and adult. Illustrations, photographs, and easy-to-read text explain: - facts about how the frog breathes and eats at each stage - differences in the metamorphosis of frogs in southern and northern climates - dangers to frogs from pollution, pesticides, and destruction of habitat
