Is the whale the world’s largest fish? No. It looks like a fish,but it is not. Then what’s the world’s largest fish? It's the whale shark.

Although the whale shark is our biggest fish and lives in many seas around the world,few people have ever heard of it. Scientists have not studied whale sharks for very long. So we know little about them.

A whale shark is sometimes called “a gentle giant (溫柔的巨人) ” It likes to be alone and doesn’t care a bit about divers or humans. The biggest whale shark weighed 55 ,500 kg and was nearly 20 metres long.

Inside its huge mouth are great numbers of very small teeth. To count all of them,you’ll need to do some maths. The whale shark’s teeth are arranged in rows. There are between eleven and thirteen rows on each jaw (顎) and around three hundred teeth in each row.

However,the whale shark rarely uses its teeth. It does not chew or bite its food. Large amounts of water is pulled into its mouth and then pushed out through its gills (鰓) .

For a few months every year,a group of whale sharks come to Ningaloo Reef,off West Australia.

This gives scientists a wonderful chance to study the large fish. Whale sharks do live in other seas of the world,but no one knows their population. It is possible that our biggest fish may need protecting. It is one of the reasons why scientists continue to learn about these gentle giants.
