Angwantibos are two species of strepsirrhine primates classified in the genus Arctocebus of the family Lorisidae. They are also known as golden pottos because of their yellow or golden coloration.
Angwantibos live in tropical Africa and their range includes Nigeria, Cameroon north of the Democratic Republic of Congo.
Angwantibos grow to a size of 22 to 30 cm, and have almost no tail at all. They only weigh up to 0.5 kg. Their fur is yellow brown to golden in color. Their snout is more pointed than that of the other lorids and this, along with their round ears, gives it the bear-like appearance that lends them their name in German: Bärenmaki, "bear lemur".
Solitary, nocturnal and arboreal, they prefer the underbrush and the lower layers of the forests. They spend the day hidden in the leaves. Like all lorisids they are characterized by slow movements.
The diet of angwantibos consists predominantly of insects (mostly caterpillars), and occasionally fruits. Owing to their careful movements and their good sense of smell, they can quietly stalk and close-in on their prey and catch it with a lightning-quick movement.
The males mate with all available females whose territory overlaps with theirs.[ citation needed ] Copulation takes place hanging onto a branch. [2] Gestation lasts 130 days and births are of a single offspring. The juvenile clasps itself first to the belly of the mother and later she may park her offspring on a branch while she goes searching for food. Within three to four months the young are weaned, at about six months it leaves its mother, and at an age of eight to ten months it becomes fully mature. The life expectancy of angwantibos is at most 13 years.[ citation needed ]
A subplot in Gerald Durrell's first book The Overloaded Ark centres on his attempts to secure an angwantibo for zoological study.

Lorisidae is a family of strepsirrhine primates. The lorisids are all slim arboreal animals and comprise the lorises, pottos and angwantibos. Lorisids live in tropical, central Africa as well as in south and southeast Asia.
Perodicticinae is a subfamily of the family Lorisidae. It includes five species of African primates as shown under taxonomy below.
Erythrocebus is a genus of Old World monkey. All three species in this genus are found in Africa, and are known as patas monkeys. While previously considered a monotypic genus containing just E. patas, a 2017 review argued that, based on morphological evidence and heavy geographic separation between taxa, E. patas should be split back into distinct species as recognised in the 19th century.
Lesser bushbabies, or lesser galagos, are strepsirrhine primates of the genus Galago. They are classified, along with the other bushbaby and galago genera in the family Galagidae. They are probably the most numerous primate in Africa, and can be found in every large forest on the continent, inhabiting forested areas, savannas, riverine bush and open woodlands.
The pottos are three species of strepsirrhine primate in the genus Perodicticus of the family Lorisidae. In some English-speaking parts of Africa, they are called "softly-softlys".
Chlorocebus is a genus of medium-sized primates from the family of Old World monkeys. Six species are currently recognized, although some people classify them all as a single species with numerous subspecies. Either way, they make up the entirety of the genus Chlorocebus.
Talapoins are the two species of Old World monkeys classified in genus Miopithecus. They live in central Africa, with their range extending from Cameroon and the Democratic Republic of the Congo to Angola.
Trachypithecus is a genus of Old World monkeys containing species known as lutungs, langurs, or leaf monkeys. Their range is much of Southeast Asia.
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 white-eyelid mangabeys are African Old World monkeys belonging to the genus Cercocebus. They are characterized by their bare upper eyelids, which are lighter than their facial skin colouring, and the uniformly coloured hairs of the fur. The other two genera of mangabeys, Lophocebus and Rungwecebus, were once thought to be very closely related to Cercocebus, so much so that all the species were placed in one genus, but Lophocebus and Rungwecebus species are now understood to be more closely related to the baboons in genus Papio, while the Cercocebus species are more closely related to the mandrill.
The Calabar angwantibo, also known as the Calabar potto, is a strepsirrhine primate of the family Lorisidae. It shares the genus Arctocebus with the golden angwantibo. It is closely related to the potto and to the various lorises.
The golden angwantibo is a strepsirrhine primate of the family Lorisidae. It shares the genus Arctocebus with the Calabar angwantibo and together they are commonly called the golden pottos. The golden angwantibo is found in Cameroon, the Republic of Congo, Equatorial Guinea and Gabon. Its usual habitat is rain forest, but it has also been known to live on farmland.
Pennant's colobus or Pennant's red colobus is a species of tree-dwelling primate in the family Cercopithecidae. It is endemic to tropical Central Africa. Three subspecies have traditionally been recognised but its distribution is peculiarly disjunct and has been considered a biogeographical puzzle, with one population on the island of Bioko, a second in the Niger River Delta in southern Nigeria, and a third in east-central Republic of Congo. It is found in rainforests and marshy forests. It is threatened by habitat loss and hunting for bushmeat.
The Gabon talapoin, also known as the northern talapoin, is a small species of African monkey native to riparian habitats in Cameroon, Equatorial Guinea, Gabon, the western Republic of the Congo and the far western Democratic Republic of Congo. It may have been introduced to Bioko and the Canary Islands. Classified in the genus Miopithecus, it was given the name Miopithecus ogouensis, based on the River Ogooué, distinguishing it from the other species, the Angolan talapoin, also known as Miopithecus talapoin.
Baboons are primates comprising the genus Papio, one of the 23 genera of Old World monkeys, in the family Cercopithecidae. There are six species of baboon: the hamadryas baboon, the Guinea baboon, the olive baboon, the yellow baboon, the Kinda baboon and the chacma baboon. Each species is native to one of six areas of Africa and the hamadryas baboon is also native to part of the Arabian Peninsula. Baboons are among the largest non-hominoid primates and have existed for at least two million years.
Allochrocebus is a primate genus including the terrestrial guenons: the L'Hoest's monkey, the Preuss's monkey, and the sun-tailed monkey.
The squirrel galagos are a group of four species of strepsirrhine primates. They are classified in the genus Sciurocheirus of the family Galagidae.
Sciurocheirus makandensis is a species of squirrel galago native to Gabon, Africa.
