On average, captive animals (especially mammals) live longer than wild animals. This may be due to the fact that with proper treatment, captivity can provide refuge against diseases, competition with others of the same species and predators. Most notably, animals with shorter lifespans and faster growth rates benefit more from zoos than animals ...

They usually live less than 15 years, although individuals that reach 12 years may live an additional 15 years. On rare occasions, wild chimpanzees may live nearly 60 years. Captive chimpanzees tend to live longer than most wild ones, with median lifespans of 31.7 years for males and 38.7 years for females. [75]
Joao, aged 82 years, 23 days, is the oldest chimpanzee ever; oldest male chimpanzee ever; and current oldest living chimpanzee. The oldest female chimpanzee ever was Little Mama, who reached to the final age of 80 years, 317 days. The oldest living female chimpanzee is Susie, aged 71 years, 23 days.
The average captive chimpanzee sleeps 9 hours and 42 minutes per day. [ 55 ] Contrary to what the scientific name ( Pan troglodytes ) may suggest, chimpanzees do not typically spend their time in caves, but there have been reports of some of them seeking refuge in caves because of the heat during daytime.
In animal studies, maximum span is often taken to be the mean life span of the most long-lived 10% of a given cohort. By another definition, however, maximum life span corresponds to the age at which the oldest known member of a species or experimental group has died. Calculation of the maximum life span in the latter sense depends upon the ...
The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
Chimpanzees live in communities of typically 20 to more than 150 members, but spend most of their time traveling in small parties of just a few individuals. The eastern chimpanzee is both arboreal and terrestrial and rests in trees at night, but spends the day on the ground.
