In the murky rivers and tangled jungles of the Amazon rain forest live some of the world's most skillful and fearsome predators. These powerful hunters are at the top of the food chain. They hunt and feed on their neighbors, but as apex predators, they have few enemies in their rain forest home. This new Science Slam! series takes a look at eight fascinating predators--from water-dwelling caiman and arapaima to jaguars that prowl the dark forest and giant harpy eagles that hunt in the forest's tallest trees. Each of the books in this series is expertly crafted to meet early elementary and science curriculum standards. Innovative, grade-appropriate activities and experiments, critical-thinking questions, and fascinating fact boxes will keep the pages turning.
