Do you know why different animals or pests(昆虫) have their special colors? Their colors seem to be used mainly to protect themselves.

Some birds like eating locusts(蝗虫)，but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of colors of crops. When crops are green，locusts look green. But as the harvest time comes，locusts change to the same brown colors as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

If you study the animal life，you will find the main use of colors is to protect themselves. Bears，lions and other animals move quietly through forests. They cannot be easily seen by hunters. This is because they have the colors much like the trees.

Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid when they face danger. While the liquid spreads over(散开)，their enemies cannot find them. And they immediately swim away. So they have lived up to now though they are not strong at all.
