Some birds like eating locusts (蝗虫), but birds cannot catch them easily. Why? Because locusts change their colors according to the colors of crops (庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others, so they have to hide (隐藏) themselves and appear (出现) only at night.
If you study animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have colors much like the trees.
A kind of fish in the sea can send out a kind of very black liquid (液体) when it faces danger. While the liquid spreads out, its enemies (敌人) cannot find it, so it can escape (逃跑) at once. That is why it can live long, though it is not strong at all.
A. are small animals
