　　A poisonous toad—unnamed and still not well understood—splashes color beside a stream in
　　
　　the Brazilian state of Paraná. In this one corner of the endangered Atlantic forest, 19
　　
　　amphibian species have been identified, and others likely await discovery. Once covering
　　
　　Brazil's entire east coast, the Atlantic forest survives in fragments, ravaged by the growth
　　
　　of agriculture, cities, and industries. Environmentalists are now racing to save what's left
　　
　　before its unique collection of plants and animals disappears forever.
