Question

【题目】Is the whale the world’s largest fish? No. It looks like a fish, but it is really a mammal. （哺乳动物）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 oceans around the world, few people have ever heard of it. Scientists have not been studying whale sharks for very long. Much more needs to be learned about them.

A whale shark is sometimes called a “gentle giant”. It likes to be alone and doesn’t care a bit about divers or humans. The biggest whale shark weighed 24,250 pounds and was nearly 40 feet long. This makes it heavier and longer than a school bus.

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 (颚) 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 are pulled into its mouth and then pushed out through its gills (鳃).

For a few months every year, a group of whale sharks comes to Ningaloo Reef, off Western Australia. This gives scientists a wonderful chance to study the large fish. Whale sharks do live in other oceans 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 all they can about these gentle giants.
