The sharks are big. They are gray and very fiercely. They have a strong tail, lt makes them swim very fast. They have a big mouth, there are many sharp teeth in it. If their teeth are blunt, they can change them in a week. Every day, they eat a lot of fish, a grown-up shark can eat fifty kilograms of fish a day. They are dangerous for us.

Some sharks never hurt people, they often live in the Ocean Park. We can watch them through the glass. I like to watch the sharks. How about you?
