The northern greater galago is a nocturnal predominantly arboreal primate. During the day, they sleep alone in trees and emerge at night. They tend to focus on a particular portion of their home range for several nights while foraging, then move on to concentrate on a new section after a short time. [4]
The brown greater galago is a nocturnal, arboreal animal. [9] During the day, it rests 5 to 12 meters (16 to 39 ft) above the ground in a dense tangle of creepers or in the hollow of a tree, rarely on an exposed branch. Female galagos will make nests, leafy platforms with foliage above to shelter their young. [7]
Lorisoidea is a superfamily of nocturnal primates found throughout Africa and Asia. Members include the galagos and the lorisids. [2]: 34–35 As strepsirrhines, lorisoids are related to the lemurs of Madagascar and are sometimes included in the infraorder Lemuriformes, [3] [a] although they are also sometimes placed in their own infraorder, Lorisiformes Gregory, 1915.
Nocturnal primates, such as the night monkeys and bush babies, are often monochromatic. Catarrhines are routinely trichromatic due to a gene duplication of the red-green opsin gene at the base of their lineage, 30 to 40 million years ago. [78] [96] Platyrrhines, on the other hand, are trichromatic in a few cases only. [97]
Galagos / ɡ ə ˈ l eɪ ɡ oʊ z /, also known as bush babies or nagapies (meaning "night monkeys" in Afrikaans [2]), are small nocturnal [3] primates native to continental, sub-Sahara Africa, and make up the family Galagidae (also sometimes called Galagonidae). They are considered a sister group of the Lorisidae. [4] [5]
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 ...
This is a list of African primates, containing all recent species of primates found in Africa including Madagascar. According to the IUCN/SSC Primate Specialist Group there are currently 216 species (111 in the mainland while the 105 are found in Madagascar). [ 1 ]
The aye-aye (Daubentonia madagascariensis) is a long-fingered lemur, a strepsirrhine primate native to Madagascar with rodent-like teeth that perpetually grow [3] and a special thin middle finger that they can use to catch grubs and larvae out of tree trunks. It is the world's largest nocturnal primate. [4]
