Chimpanzee teeth7/1/2023 I surveyed some of our caregivers for their favorite fun facts about chimpanzees are, as well as some myths they’d like busted about the species. It’s safe to say that caring for chimpanzees – let alone more than 270 of them – is a unique profession! Caregivers are often asked what it is like to work with chimps from friends, family, and sanctuary guests. Like humans, chimpanzees have two sets of teeth in their lifetime: a set of “baby teeth” that fall out as the chimpanzee grows older, and a second set of permanent teeth, usually by the time an individual is 11years old.By Jordan Green, Chimp Haven Animal Caregiver Inside that mouth is a set of 32 teeth, same as adult human primates. A flattened muzzle gives way to a wide mouth with slightly protruding lips. A dramatic, bony brow ridge (known as a sagittal crest) defines the forehead, beneath which Mother Nature has set brown, animistic eyes that assess the world. They have an opposable big toe on each foot that can pluck fruits from trees.Ĭhimpanzee faces are full of character. Long arms dangle below the knees, and their hands are fitted with long, slender fingers and short, opposable thumbs. Being great apes, chimpanzees lack a tail. Rumps of infant chimpanzees are adorned with a white tuft of hair that disappears as an individual ages. The face, ears, palms, and soles of feet are bare. That said, based on the slim information they have gleaned, researchers have conjectured that Nigeria-Cameroon chimpanzees have a darker face, longer hair on the sides of their head and cheeks, and slightly smaller ears than the other chimpanzee subspecies.Īpart from any nominal characteristics that may distinguish this subspecies, the Nigeria-Cameroon shares physical traits typical of all chimpanzees.Ī sturdy body is covered with dark brown or black hair. Furthermore, a lack of DNA testing of captive individuals makes distinctions between the four subspecies difficult. Photographs of this Endangered subspecies in their wild habitat are scarce. Nigeria-Cameroon chimpanzees may not be camera-shy, but these barrel-chested primates are elusive. More importantly, additional studies could help researchers better understand and, hopefully, preserve all four common chimpanzee subspecies-including the enigmatic and rare Nigeria-Cameroon chimpanzee. The central and eastern chimpanzees share their own evolutionary relationship.įurther genetic and ecological research may lead to the recognition of more or fewer subspecies classifications, within the common chimpanzee’s descending taxonomic hierarchal order. In fact, prior to receiving its own subspecies classification in 1997, the little-studied Nigeria-Cameroon chimpanzee had been recognized as a western chimpanzee (the two share a common ancestor from 0.4 to 0.6 million years ago!). Genetic data shows a close evolutionary relationship between Nigeria-Cameroon and western chimpanzees. Subspecies classification is based, in part, on differences in appearance and distribution. Currently, the International Union for the Conservation of Nature (IUCN) recognizes four subspecies of the common chimpanzee ( Pan troglodytes), assigning each a conservation status. The discipline of taxonomy is fluid, often yielding new discoveries. An ecotone is a region of transition between biological communities.įarmland provides Nigeria-Cameroon chimpanzees with an unnatural, inapposite habitat. Each occupies a different ecological niche: one group resides in the country’s western rainforests, while the other resides in central Cameroon’s forest-woodland-savanna mosaic ecotone, which includes include gallery forest, dry forest, semi-deciduous forest, and open grasslands. In Cameroon, the subspecies is composed of two genetically distinct populations. Habitat for this once widespread, and now Endangered, primate includes primary and secondary moist lowland forest, montane and submontane forest. Geographic distribution is restricted to isolated patches of forest within southwestern Nigeria, the Nigeria Delta and floodplain, and to Nigeria’s eastern border north of the Sanaga River, before stretching southwesterly into the forests of Cameroon. The Nigeria-Cameroon chimpanzee ( Pan troglodytes ellioti), sometimes called Elliot’s chimpanzee, is native to the two African countries that give it its namesake.
