Sharks are amazing fish that have been around since long before dinosaurs existed. They live in waters all over the world, in every ocean,and even in some rivers and lakes. The largest sharks are decreasing in numbers around the world because they are hunted by people. The numbers of the Great White shark, Basking shark and Whale shark are all waning. Believe it or not, sharks are endangered. Most sharks only reproduce once every couple of years, and some sharks do not mature until they are 25 years old.
