Sharks are the most fearsome predatory fish of the seas. There are 375 species of sharks. They live mostly in warm seas.

Their torpedo-shaped bodies make them very fast swimmers. Sharks have a skeleton made of rubbery cartilage. Most other kinds of fish have bony skeletons.

The world’s biggest fish is the whale shark. It can grow well to over 12 metres long. Unlike others sharks, the whale shark and the basking shark mostly eat plankton and are completely harmless.

Sharks main weapon are its teeth. They are powerful enough to bite through steel plate. The killing machine of the shark world is great white shark. This shark is responsible for most attacks on humans. Up to 20 people die from recorded shark attack each year. So, be careful when you swim in the sea.
