Shark 鲨鱼 (4)

Most sharks are hard to see. They have a dark back. From above, they blend in with the water. They have a white belly. From below, they blend in with the sky.

Some sharks have special ways to hide. Wobbegongs have colors like the seafloor. Their mouths have parts that look like seaweed. Fish swim in but they can’t get out!

One day Bethany Hamilton went surfing. A tiger shark tugged her as she held onto her surfboard. It took a big bite out of her surfboard. It also took Bethany’s left arm. After that, Bethany wanted to keep surfing. She is not afraid to go in the water. Bethany says, “One thing hasn’t changed - and that’s how I feel when I’m riding a wave.”

Shark are scary, and terrible. Sharks can be a danger to people. But people are a bigger danger to sharks. Millions of sharks die in nets set to catch other fish. Others are killed on purpose.

Many types of sharks may become extinct. Sharks have been on Earth for millions of years. Sharks and people need to learn to share the sea.
