The tiger is the largest wild cat in the world. The big cat weighs about 363 kilograms and is about two metres long.
Tigers wait until it's dark, then they go out to find their food. When a tiger sees an animal, it moves very quietly, then jumps on the animal to kill it. It can take several days for a tiger to finish eating its kill. The tiger stops eating until it has had enough, and then it covers the dead animal with leaves. Later, when the tiger is hungry again, it comes back to eat more.
Tigers are different from others in the cat family: they like water, and they often jump into rivers to swim.
Some tigers live in very cold places--in parts of North Korea, Eastern Russia and Northeast China. Other tigers live in warm places一in India and parts of southeast of Asia.
All tigers are in danger. People kill them to use their skin for clothes and their bones for medicine. In addition, there is also less and less land for tigers to live on. But now people know that tigers are in danger and have made plans to protect them.
