It's early morning in the Amazon rain forest. A caiman glides through the waters of a muddy river. Suddenly, with a huge splash, a jaguar leaps from its hiding place on the riverbank. In an instant, the jaguar sinks its sharp teeth into the caiman's thick, scaly skin. The caiman struggles and tries to fight back, but it's no match for the powerful jungle cat. Filled with information perfectly suited to the abilities and interests of its primary-grade audience, this colorful, fact-filled book gives readers a chance not only to learn all about jaguars and their Amazon rain forest home, but also to develop their powers of observation and critical thinking. Built-in investigations, such as figuring out how the jaguar's fur pattern helps it to hunt, and measuring the predator's sharp canine teeth, give readers a chance to gain insights beyond the facts and figures.
