Tropical rainforests are home to brilliantly colored birds and spider monkeys that swing like acrobats. Here, tiny tadpoles, lizards, and crabs live in sky-high penthouse mini-ponds formed in the leaves of rootless plants. The understory and forest floor swarm with insects, worms, frogs, toads, and millions of marching army ants. But beware! There are poisonous butterflies, frogs, and insects; venomous snakes; and plants that can paralyze. Now, you can enter this wild world! Award-winning science writer Seymour Simon has teamed up with the Smithsonian Institution to take you on an exotic, full-color photographic adventure.
