【題目】 Think of the animal world. And a group of colorful wild animals will spring to mind: a parrot's rainbow feathers or the showy scales of sea fish. But, many mammals(哺乳動物) on the planet come in only two colors: black and white. Spend some time exploring what science has discovered about these animals' appearances, and you’ll see that basic black and white isn't so basic at all.

The panda's white body helps it hide in snowy areas. The arms and legs are black, helping it hide in forests. The markings on its head are not used to hide, but to communicate. Black ears can act as a warning to enemies.

Depending on the species, black skunks(臭鼬) may wear white spots that act as covering or white stripes that signal enemies to be aware of their smelly spray, which causes no real harm to its victims, but it makes them uncomfortable.

Zebras' thin coats make them more vulnerable than long-haired animals to biting flies that carry disease, but the coats stripes prevent flies from landing on them, for reasons that scientists are still studying. Further, their attractiveness to flies increases with stripe width. No two zebras' stripes are exactly the same.
