Sharks are the most feared predators of the seas. Evolution has honed them over millions of years into perfect killing machines. Sometimes they hunt not only their prey, but also humans. This captivating BBC documentary offers a unique ranking: it profiles the largest, fastest, and those with the most powerful bite—the ten most dangerous sharks in the world. Using carefully filmed scenes and animations, it reconstructs how these marine predators hunt and what makes them dangerous to humans. There are a few surprises: contrary to popular expectation, the great white shark is not at number one. That spot is occupied by another, relatively unknown shark that has been proven to have claimed 67 lives. Despite their reputation, sharks are not monsters. It is always humans who invade their territory, diminish their habitat, destroy their food sources, and persecute them relentlessly. As a result, many shark species are now considered endangered.
