The Nose of the Wolf

 Nose

The wolf's sense of smell is about 100 times better than a ®human's¯. It uses its sense of smell more than anything else to find ®prey¯, with the ability to smell ®prey¯ before it can see it, more than a mile away if the wind is right. A wolf's nose can smell things that your nose can't. Like your nose, the inside of a wolf's nose contains moist surfaces that "catch" smells in the air. The wolf's nose has about five times more surface area than yours does, so it can catch more smells from the air than you can. It can even sense the presence of an ®animal¯ three days after it's gone! The nose itself is not five times larger than a ®human¯ nose. For all the extra smelling surface to fit inside, it must be wrapped and folded many times.
