El Ciclo de Vida de la Rana - Second Edition (the Life Cycle of a Frog)

Frogs begin their lives as tiny tadpoles living in water. As adults, they live both on land and in water. This book details the changes in a frog at the four stages: egg, tadpole, froglet, and adult. Readers will learn about topics such as how frogs breathe and eat at each stage, differences in the metamorphosis of frogs in different climates, and dangers to frogs from pollution, pesticides, and destruction of habitat. Features include audio, full-color photographs, glossary of key words, index, informative sidebars, and table of contents.
