In the original Planet of the Apes film series chimpanzees were considered intellectuals, scientists, doctors, and citizens of the ape society. The chimpanzees are one of the primary known species of all apes within the Planet of the Apes franchise, and also the majority of the population, which is ironic because there are fewer than 300,000 wild chimpanzees in the world today. 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. Field staff and researchers monitor the life. As with bonobos and gorillas, chimps move quadrupedal by knuckle-walking, which probably evolved independently in Pan and Gorilla. Over the years, Gombe researchers have witnessed and recorded entire lifespans of individual chimpanzees. On the ground chimps move both quadrupedal and bipedal, which appear to have similar energy costs.
Arboreal locomotion consists of vertical climbing and brachiation.
#Chimpanzee lifespan 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. At age 15 chimpanzee life expectancy is an additional 15 years. A chimp's head is rounded with a prominent and prognathous face. In natural habitats chimpanzees have a much shorter adult lifespan than humans. The feet are adapted for grasping, the big toe being opposable. Captive chimps live longer with median lifespans of 31.7 years for males and 38.7 years for females. Wild individuals may live over 27 years and occasionally over 60. The hands have long fingers with short thumbs and flat fingernails. The average lifespan of a chimpanzee is usually less than 15 years. 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.
