11.The crab is a living clock.It tells the time of the day by the colour of its skin,which is dark by day and pale by night.The crab's changing skin colour is a regular twenty-four hour cycle(周期)that follows the daily rhythm(循环)of the sun.
    Does the crab really keep time,or is its skin simply affected by the sun's rays(光线),changing colour with the amount of the sunlight?To find out the answer,scientists kept some crabs in a dark room for two months.Even without daylight the crabs'skin colour continued to change.
