As darkness falls over the Amazon rain forest, a large black caiman waits in a slow moving, muddy river. Only the reptile's eyes and nostrils are visible above the water. The caiman is watching a young deer that has come to the river to drink. As the deer dips its head toward the water, the caiman attacks. In just a few seconds, the large predator has dragged the deer under the water. Filled with information perfectly suited to the abilities and interests of its primary grade audience, this colorful, fact-filled book gives readers a chance to learn about the lives of apex predators. The book will also help readers develop their powers of observation and challenge them with activities and critical-thinking questions about the caiman's physical characteristics, its everyday life, and its hunting abilities.
