Chimpanzees are covered with black hair on most of their body (except their fingers, palms, armpits, and bottoms of their feet). Baby chimpanzees have very pale skin in the areas that have no hair and a white tuft of hair on the rump.
Senses:
Chimpanzees have senses very similar to ours, including hearing, sight, smell, taste, and touch.

Face:
Chimpanzees have a slight brow ridge, large ears, small nostrils, and an elongated snout. They are capable of many expressions. Chimpanzees have a hairless face except for a short, white beard in both male and female adults. Some adult females become bald.

SIZE
Male chimpanzees are larger than the females.
| Chimpanzees | Height | Weight |
| Female | 2-3.5 ft (0.66 -1 m) | 57 -110 pounds (26 - 50 kg) |
| Male | 3-4 ft (0.9-1.2 m) | 90 - 115 pounds (35 - 70 kg) |
BEHAVIOR AND SOCIAL HABITS
Groups of Chimpanzees:
Chimpanzees are social animals that are active during the day (they are diurnal). They live in small, stable groups (called communities or unit groups) of about 40-60 individuals. Smaller subgroups of 6-7 chimps stay together for a while, with the membership changing over time.
Grooming:
Grooming one another (cleaning the hair of another chimp) is a major occupation among chimpanzees in a group.

Sleeping Nests:
Each evening, chimpanzees construct a fresh "sleeping nest" in the trees where they will curl up and sleep. These bowl-shaped nests are made out of leaves and other plant material. Nests are only shared by a mother and her nursing offspring.
Play:
Young chimpanzees play a lot, learning skills they will use as an adult. They practice using tools, making sleeping nests, climbing, wrestling, etc.

HABITAT
Chimpanzees live in a wide variety of habitats, including tropical rain forests (in the forest edges and clearings), woodlands, swamp forests, and grasslands in western Africa.
COMMUNICATION
Sounds:
Chimpanzees have a complex system of communication. They have cries that warn other chimps of danger in the area; their danger call can be heard through the forest for about 2 miles (3 km). When there is an abundance of food, chimps bark loudly to call the others in their group to a feast.
Gestures:
Chimpanzees also use many gestures to indicate needs and emotions. Chimps will beg other chimps for food by approaching them with open hands. Friends may hold hands, hug, or even kiss. A worried chimp makes a lip-puckering face. A frightened chimp will bare its teeth. A smile indicates a relaxed, friendly chimp. When the lips are tightly pressed together, the chimp is ready to attack.
