Sharks are almost perfect predators, and they’ve been pursuing their prey in the oceans for over 400 million years. Some are big, fast, and dangerous, with powerful jaws filled with razor-sharp teeth. Others are gentle giants, cruising slowly through the sea as they feed on shrimp and other tiny animals. The largest shark is as big as a bus, while the smallest could fit in the palm of your hand. Some of the strangest and most unfamiliar sharks live in deep, dark waters and are almost never seen by humans.
