Chimpanzees
are about 3 to 5 feet tall and weigh from 99 to 176
pounds. They have black hair. Adults are very often
bald, usually a triangle on the forehead of the
male, and more complete baldness in females. Their
faces are hairless. Infants have pink faces which
turn darker with age. Although chimpanzees have no
tail, infants have a white tail tuft.
