Hello everyone, I am a kind of fish called "the overlord of the sea". Guess who I am? Maybe you have seen me on TV. I am the famous Great White Shark.
I look very fierce. Some small fish will either be scared to death or swim away as soon as they see my shadow. Let me tell you two secrets: The first is that we sharks do not have swim bladders. The second is that we sharks have to replace their teeth thousands or even tens of thousands of times in their lives, once every 4 hours. Are you surprised?
In the past, I had countless shark brothers, but now humans often hunt us, causing our number to drop sharply. If humans don't stop this behavior, we will become extinct. We are powerless in the face of the ruthless hunting of humans, so children, please come and protect us!
