Sharks are the sea's most feared predators, and many people think of them as ferocious monsters - but they are also fascinating, graceful and powerful creatures that evolved long before dinosaurs. Their physiological, anatomical and behavioural adaptations enable them to capture, ingest and digest food as efficiently as possible. With this extraordinary constitution, a variety of animals have been discovered in the stomachs of sharks in various locations. The contents include swordfish, sharks, seals, whales, dolphins, marine turtles, sea birds, an entire reindeer without horns, as well as a variety of indigestible oddities! Photographs complement the most complete and updated text on diets and predatory tactics of sharks. Answers are provided to a myriad of questions, such as: What predatory tactics do sharks use to catch their prey? Why do some attack humans? Which animals are especially vulnerable to shark predation? Find out more about these misunderstood and highly endangered animals.
