The West African potto (Perodicticus potto) is a species of nocturnal strepsirrhine primate. It is found in tropical West Africa. It is also known as Bosman's potto, after Willem Bosman, who described the species in 1704. It is the type species of the genus Perodicticus . [2] [3]

Taxonomy

This species was formerly considered the only species in the genus Perodicticus, but a 2015 study split it into three species, with only the name Perodicticus potto only applying to the West African population. [4]

Phylogenetic evidence supports the West African potto being the most basal member of the genus Perodicticus, with the other two species being sister species to one another. It is thought to have diverged from the other species during the mid-late Miocene, between 6-10 million years ago. [4]

The mysterious "false potto" (Pseudopotto martini) is now thought to have been a misidentified specimen of West African potto. [3]

Distribution

This species ranges from Guinea west to Nigeria, with an disjunct population in eastern Senegal. The Niger River serves as the eastern barrier to the species' range, separating it from the Central African potto (P. edwardsi). [1]

Ecology

One population of chimpanzees living in Mont Assirik, Senegal, was observed to eat West African pottos, taking them from their sleeping places during the day; however, this behaviour has not been observed in chimps elsewhere. [5]

Conservation

Although this species is known to survive in disturbed forests near human habitation, population growth and subsequent habitat destruction in West Africa are of major risk to the species. Heavy deforestation for industrial agriculture is thought to have led to rapid population declines in the species. In addition, this species is more frequently hunted for bushmeat due to a decline in larger animals to hunt, which has in turn also caused pottos to become rarer. Due to this, it is classified as Near Threatened on the IUCN Red List. [1]

<span class="mw-page-title-main">Chimpanzee</span> Species of great apes

The chimpanzee, also simply known as the chimp, is a species of great ape native to the forests and savannahs of tropical Africa. It has four confirmed subspecies and a fifth proposed one. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus Pan. Evidence from fossils and DNA sequencing shows that Pan is a sister taxon to the human lineage and is thus humans' closest living relative. The chimpanzee is covered in coarse black hair, but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more robust than the bonobo, weighing 40–70 kg (88–154 lb) for males and 27–50 kg (60–110 lb) for females and standing 150 cm.

Black-and-white colobuses are Old World monkeys of the genus Colobus, native to Africa. They are closely related to the red colobus monkeys of genus Piliocolobus. There are five species of this monkey, and at least eight subspecies. They are generally found in high-density forests where they forage on leaves, flowers and fruit. Social groups of colobus are diverse, varying from group to group. Resident-egalitarian and allomothering relationships have been observed among the female population. Complex behaviours have also been observed in this species, including greeting rituals and varying group sleeping patterns. Colobi play a significant role in seed dispersal.

<i>Pan</i> (genus) Genus of African great apes

The genus Pan consists of two extant species: the chimpanzee and the bonobo. Taxonomically, these two ape species are collectively termed panins. The two species were formerly collectively called "chimpanzees" or "chimps"; if bonobos were recognized as a separate group at all, they were referred to as "pygmy" or "gracile chimpanzees". Together with humans, gorillas, and orangutans they are part of the family Hominidae. Native to sub-Saharan Africa, chimpanzees and bonobos are currently both found in the Congo jungle, while only the chimpanzee is also found further north in West Africa. Both species are listed as endangered on the IUCN Red List of Threatened Species, and in 2017 the Convention on Migratory Species selected the chimpanzee for special protection.

<span class="mw-page-title-main">Slow loris</span> Genus of primates from Southeast Asia

Slow lorises are a group of several species of nocturnal strepsirrhine primates that make up the genus Nycticebus. Found in Southeast Asia and bordering areas, they range from Bangladesh and Northeast India in the west to the Sulu Archipelago in the Philippines in the east, and from Yunnan province in China in the north to the island of Java in the south. Although many previous classifications recognized as few as a single all-inclusive species, there are now at least eight that are considered valid: the Sunda slow loris (N. coucang), Bengal slow loris (N. bengalensis), Javan slow loris (N. javanicus), Philippine slow loris (N. menagensis), Bangka slow loris (N. bancanus), Bornean slow loris (N. borneanus), Kayan River slow loris (N. kayan) and Sumatran slow loris. A ninth species, the pygmy slow loris (X. pygmaeus), was recently moved to the new genus Xanthonycticebus. After the pygmy slow loris, the group's closest relatives are the slender lorises of southern India and Sri Lanka. Their next closest relatives are the African lorisids, the pottos, false pottos, and angwantibos. They are less closely related to the remaining lorisoids, and more distantly to the lemurs of Madagascar. Their evolutionary history is uncertain since their fossil record is patchy and molecular clock studies have given inconsistent results.

<span class="mw-page-title-main">Red colobus</span> Genus of Old World monkeys

Red colobuses are Old World monkeys of the genus Piliocolobus. It was formerly considered a subgenus within the genus Procolobus, which is now restricted to the olive colobus. They are closely related to the black-and-white colobus monkeys, and some species are often found in groups with the blue monkey. The western red colobus is frequently hunted by the common chimpanzee.

The false potto is a lorisoid primate of uncertain taxonomic status found in Africa. Anthropologist Jeffrey H. Schwartz named it in 1996 as the only species of the genus Pseudopotto on the basis of two specimens that had previously been identified as a potto (Perodicticus). The precise provenances of the two specimens are uncertain, but at least one may have come from Cameroon. Schwartz thought the false potto could even represent a separate family, but other researchers have argued that the supposed distinguishing features of the animal do not actually distinguish it from the potto; specifically, the false potto shares several features with the West African potto.

The slender lorises (Loris) are a genus of loris native to India and Sri Lanka. The genus comprises two species, the red slender loris found in Sri Lanka and the gray slender loris from Sri Lanka and India. Slender lorises spend most of their life in trees, traveling along the tops of branches with slow and precise movements. They are found in tropical rainforests, scrub forests, semi-deciduous forests, and swamps. The primates have lifespans of approximately 15 years and are nocturnal. Slender lorises generally feed on insects, reptiles, plant shoots, and fruit.
