The physical strength of chimps is around 1.5 times greater than humans, due to higher content of fast twitch muscle fibers, one of the chimpanzee's adaptations for climbing and swinging. As with bonobos and gorillas, chimps move quadrupedal by knuckle-walking, which probably evolved independently in Pan and Gorilla. On the ground chimps move both quadrupedal and bipedal, which appear to have similar energy costs.
Arboreal locomotion consists of vertical climbing and brachiation.
#Gorilla vs chimpanzee skin#
The skin may range from pale to dark, females develop swelling pink skin when in oestrus.Ĭhimpanzees are adapted for both arboreal (travelling by trees) and terrestrial locomotion. As they get older, white or grey patches may appear, particularly on the chin and lower region. The hair of a chimp is typically black but can be brown or ginger. Chimps lose more hair as they age, and develop bald spots. It has forward-facing eyes, a small nose, rounded non-lobed ears, a long mobile upper lip and, in adult males, sharp canine teeth.Ĭhimpanzee bodies are covered by coarse hair, except for the face, fingers, toes, palms of the hands, and soles of the feet. A chimp's head is rounded with a prominent and prognathous face. The feet are adapted for grasping, the big toe being opposable. The hands have long fingers with short thumbs and flat fingernails. The arms of a chimp are longer than its legs, and can reach below the knees. The build is more robust than the bonobo's but less than the gorilla's. Adult males weigh between 88–132 lb while females weighing between 60–110 lb. Chimpanzees have a standing height of 3.3–4.6 ft tall.
