Do you know why different animals or pests (昆虫) have their special colors? Colors in them 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 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 themselves for lives and appear only at night.

If you study the 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 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 (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

How Do Animals Catch Their ZZZ’s?

Different creatures have developed some pretty creative ways to get their rest and stay safe. The lizard（蜥蝎）likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest. If a snake tries to slither up the branch to eat it ,it will shake the branch and knock the lizard off ,and the lizard will fall safely into the water. Chameleons can change color to match their surroundings in order to hide even while sleeping.

Corillas（大猩猩）like to sleep high in the trees. They build a new bed every night, sometimes taking up to half an hour to pile branches ,twigs ,and leaves into a comfortable bed .Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks ,they don’t use a nest .They just lock their feet around a branch and hang on .A special tendon（腱）in their legs in automatically tight when they are at rest ,so they won’t let go and fall.

Dolphins live underwater ,but must come to the surface to breather .Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing. Seals also do this ,lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface. Some ducks may also have this ability, and actually sleep with one eye closed and one eye open.
