It may seem as though sharks are perfectly equipped to defend themselves and catch prey. However, in an environment where competition for food is fierce and sharks' predators are equally well-adapted, sharks need to have a few tricks to fall back on. From the cookiecutter shark, which tricks its much larger prey into thinking it's a tiny fish, to the wobbegong shark, which lays flat on the ocean floor to camouflage itself, readers learn about the amazing variety of sharks and the ways they have evolved to survive. Full-color photographs and engaging fact boxes bring each shark to life.
