There are some 65 species of New World monkeys. Many of these have a very useful anatomical adaptation lacking in their old world counterparts that curious “fifth hand’’, the prehensile （适手抓住的）tail. And in a few species the gripping tail has developed to such as extent that is actually has “fingerprints” on the tip. While of course a tail is not-accepted with fingers, it can sometimes be even more useful than an arm or a leg. A spider monkey’s tail, for instance, is longer than its head and body combined, and is frequently used instead of a hand to grasp distant objects. Other monkeys less fortunate are forced to relegate at least one limb to support while they feed, whereas monkeys endowed with prehensility can hang by their tails while they feast with both hands and feet.
