Monsters of the sea

It’s hard to solve the sharks’ “ image” problem and change people’s minds about them. Sharks are hunters and so they naturally kill. But actually elephants kill more people than sharks every year – and every–one likes elephants. Sharks are very important for the world’s oceans. They eat unhealthy fish and keep the numbers of different kinds of sea animals in balance. Now scientists are trying to find way to protect these animals. They have been in the oceans for 350 million years. Perhaps they can survive a little longer.
