[5] They possess flat thickened skin pads at the ends of their fingers and toes for grasping limbs.

[6] The thick fur is highly variable in color, depending on the subspecies: O. c. crassicaudatus exhibits dorsal pelage ranging from buff to gray extending to the face, flanks and limbs.

The tail is usually light brown in this subspecies and the feet and hands lack darkening pattern.

The brown greater galago exhibits sexual size dimorphism with males being larger than the females.

The largest populations are found in Angola, Tanzania, southern Kenya and the coast of Somalia.

[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] Its diet consists of fruit (like berries, figs), seeds, acacia gum, flowers, insects, slugs, and even reptiles and small birds.

[10] In O. crassicaudatus, the penis is on average 20 mm (0.79 in) in length and increases in width towards the distal tip.

The glans and shaft are covered in single keratinised penile spines that point towards the body.

[7] Mating patterns can be either monogamous or polygynous, often determined by the overlapping of host ranges and competing of males for best territories.

[6] The brown greater galago is listed as Least Concern by the International Union for Conservation of Nature (IUCN).

Habitat fragmentation is increasing across their range, with sugar cane and forestry in South Africa being a main cause.
