Which animal do you think is "the king of animals", the elephant, the lion or the tiger? They are all large and strong. But I think the tiger is "the king of animals". If you watch carefully, you can find some black lines (线条) on the tiger's forehead. The lines look like a Chinese word. The word means "the king of the world" in Chinese.
Most tigers come from China and India. Tigers are dangerous animals. They look scary. They like eating meat. They have yellow fur(毛皮) with black lines. They usually weigh about 200kg to 300kg. Tigers can run fast. They run at a speed of20 meters per second.
Some people are afraid of tigers, but they don't know tigers are in danger now. Lots of people kill them for their fur. We should take measures(措施) to protect them.
