Sharks are in every ocean in the world. They can only swim forward. And they can
have several rows of teeth. The smallest shark is about 6 inches and the largest
is over 40 feet. The great white shark is known to attack people. Whenever they are spotted,
lifeguards tell people to get out of the water. They often mistake people for penguins. And they
love to eat penguins. They are known as the silent killer. They make no sounds. And they've been
around for millions of years.
If a great white shark is around, it's best to get out of the water.
