Underwater, near the edge of a river, a little tadpole emerges from an egg. So begins the life of an American bullfrog. In this coming-of-age introduction to these fascinating amphibians, readers will learn that a female bullfrog lays up to 20,000 eggs. Then, when a tadpole hatches, it may spend up to three years growing and changing into a frog. Children will see how the tadpole grows back legs, then front legs, and finally loses its tail to become a fully-grown, adult bullfrog. The colorful interior spreads and gorgeous photos of tadpoles and frogs are sure to delight emergent readers. Water Frog Polliwogs is part of Bearport's Water Babies series.
