Otolemur

Otolemur is a genus of small, nocturnal primates in the family Galagidae, commonly known as galagos or bush babies. They are native to sub-Saharan Africa, inhabiting forests, woodlands, and savannas. The genus currently comprises two widely recognized species: Otolemur garnettii, the Garnett's galago, and Otolemur crassicaudatus, the fat-tailed galago. Some classifications have placed different populations within alternative genera; taxonomic revisions continue.

Physically, Otolemur species are small, with a body length of roughly 9 to 15 cm and a tail of comparable or greater length. They weigh around 0.25 to 0.6 kg. They have large eyes and ears adapted for nocturnal vision and sound localization. The tail is long and in the fat-tailed galago, stores fat reserves, which helps during food-scarce periods.

Behaviorally, they are arboreal and highly agile leapers, using powerful hind limbs to jump between branches. They are mainly nocturnal and elusive, often solitary or living in small family groups. Their diet is omnivorous, consisting of insects, fruit, gum from trees, and occasionally small animals.

Reproduction is seasonal in some populations, with females giving birth to one or two offspring after a gestation period of about four months. Threats include habitat loss and fragmentation, though both species are listed as Least Concern on the IUCN Red List; local populations may be impacted by deforestation and hunting. Otolemur is closely related to other galagos in Galagidae and shares their characteristic nocturnal lifestyle.
