In nature, you may see many insects （昆虫）and animals of different colors. Have you ever wondered why?
Locusts are super delicious food for birds, But it is not always an easy job for birds to catch them. It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops（庄稼）. When crops are young, locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do. Butterflies and bees living among the flowers are colorful like flowers.
Brown bears, tigers and other animals move quietly through forests. They can’t be seen easily by their game. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white.
Have you ever noticed some even stranger acts? The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over, its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.
