For many years sharks ruled as fast swimming hunting machines. This might be surprising, but they do it without a bone in their body. If you want to ask what their body is made of, it is made up of cartilage, a thick elastic substance. There are two different type of sharks you will learn about. One of them is called the whale shark. The whale shark is the largest shark of them all. It is forty six feet long and it is also longer than __two__ school buses. Whale sharks feast only on plankton. They eat about two hundred fifty planktons in one day. That’s because they are so small. Whale sharks also migrate vast distances.

The other shark is called the Wobbegong. Wobbegongs are master disguisers. They are also sometimes called carpet sharks because of their appearance. To survive, most sharks have to swim alot to get oxygen into their lungs. But Wobbegongs survive differently. They are ambush sharks. So this means that they ambush their prey. Wobbegongs lived in the ocean for almost 160 million years. In conclusion, sharks are being hunted and attacked. One reason is because the people think that they eat and attack human beings so they feel that they should kill them. But some sharks are actually nice. So even you know that sharks are a great part in life.
