A few seals are playing in the waves near a shore. Suddenly a dark, triangle-shaped fin appears above the water's surface. When the seals see the fin headed toward them, they scatter in all directions as fast as they can. They know that one of the scariest predators in the sea—a great white shark—is headed their way! Young readers will explore the underwater world of this enormous fish through clear text, full-color photos, and diagrams. Age-appropriate activities, such as describing the differences between an adult and a pup, give readers a chance to make observations and to develop animal-science skills.
