Chimpanzee Face Close-up At Kibale National Park, Uganda Stock Photo

This great ape is one of our closest relatives, sharing about 98 percent of their genes with us. They have thickset bodies with short legs, opposable thumbs, no tails, and long arms that are 1.5 times their height that extends beyond their knees. Much of their body is covered with long black hair, but the face, ears, fingers, and toes are bare.
