The golden angwantibo (Arctocebus aureus) is a strepsirrhine primate of the family Lorisidae. It shares the genus Arctocebus with the Calabar angwantibo (Arctocebus calabarensis) 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.

Like the Calabar angwantibo, the golden angwantibo weighs between 266 and 465 grams and has a stumpy tail, abbreviated index fingers, a specialised grooming claw on each foot and a white line on its face. It can be distinguished from its cousin largely by its colour. The fur on its back is red-gold, with a more muted red on its belly. Unlike the Calabar angwantibo, the golden angwantibo has no nictitating membrane.

The golden angwantibo is a nocturnal and arboreal species that is typically found on small branches 5–15 metres above ground. Its diet consists of around 85% insects (especially caterpillars) and 14% fruit. Its foraging, antipredator, social and reproductive behaviour are extremely similar to those of the Calabar angwantibo.

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 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 (.

<span class="mw-page-title-main">Plica semilunaris of conjunctiva</span> Small fold of mucous membrane in the eye.

The plica semilunaris is a small fold of bulbar conjunctiva on the medial canthus of the eye. It functions during movement of the eye, to help maintain tear drainage via the lacrimal lake, and to permit greater rotation of the globe, for without the plica the conjunctiva would attach directly to the eyeball, restricting movement. It is the vestigial remnant of the nictitating membrane which is drawn across the eye for protection, and is present in other animals such as birds, reptiles, and fish, but is rare in mammals, mainly found in monotremes and marsupials. Its associated muscles are also vestigial. It is loose, thus eye movements are not restricted by it. Only one species of primate, the Calabar angwantibo, is known to have a functioning nictitating membrane.

<span class="mw-page-title-main">Slender loris</span> Genus of primates

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.

Nephelomys auriventer, also known as the golden-bellied oryzomys or Ecuadorian rice rat, is a species of rodent in the genus Nephelomys of family Cricetidae. Oldfield Thomas originally described it, in 1899, as a species of Oryzomys, Oryzomys auriventer, and considered it most similar to Oryzomys aureus. In 1926, a subspecies was described from an Ecuadorian locality, Oryzomys auriventer nimbosus, and it was suggested that O. auriventer was closely related to O. albigularis. This proposal was formalized in 1961 by including O. auriventer within the species O. albigularis, but by 1976 O. auriventer was recognized again as a separate species. In 2006, Oryzomys albigularis and related species, including O. auriventer, were transferred to the new genus Nephelomys. Simultaneously, the former subspecies nimbosus was recognized as a separate species, Nephelomys nimbosus.
