【英语时差8,16】动物肚皮上的轻皮毛（上）

（单词翻译）

Ever notice how many animals have lighter¹ fur on their bellies² than on their backs? Think about it. Cats and dogs often have lighter-colored bellies. Deer and foxes. Wolves. Coyotes. Chipmunks³. You get the idea. But Why? We can understand, for example, why a zebra has stripes–stand it in among a clump⁴ of trees or grasses and it is well camouflaged⁵. The same holds true for other fur patterns. They are ways of fitting in so that you won’t easily be seen. A pale belly⁶, in fact, serves the same function–it helps you blend into your background rather than stand out.
