Attack!

The great white shark is one of the most ferocious predators in the oceans. Although it has been known to attack and kill humans, this is rare; it usually feeds on fish, turtles and sea mammals, such as dolphins and seals.
Sharks usually attack their prey from underneath so that they are taken by surprise. Sometimes they hit their prey with such force that they leap out of the water. Sharks do not chew their food. Instead, they tear off chunks of flesh with their teeth and swallow them whole.

Great white sharks find their prey using their excellent sense of smell. They can detect a single drop of blood in 100 litres (25 gallons) of water. They can even sense tiny amounts of blood in the water up to 5 km (3 miles) away.
