Most people are afraid of sharks, but they usually do not know much about them. For example, there
are about 350 species of sharks that live in oceans over the world. All of the sharks are carnivores, but
most of them don't attack people. Some sharks are very small - the smallest shark is about 6 inches
long - about as long as your hand. But some sharks are very large. The largest species of sharks may
be 60 feet long and weigh 15 tons. Unlike many other kinds of fish, sharks do not have bone. Their
bodies are made up of a kind of tough white flexible material (called cartilage). Sharks do not have
ears. However, they 'hear' sounds and movements in the wade. Any sound or movement makes the

large eyes to find food, too. Most sharks see best in low light. They often hunt for food at dawn. in
