They have very large eyes typical of nocturnal animals. Genus Galago have large ears with four transverse ridges and can be independently or simultaneously bent back and wrinkled downward from the tips. This frequent furling and unfurling produces a quizzical expression characteristic of the genus. Range varies with species but includes most of the forested and bush regions of Africa south of the Sahara including some of the nearby islands such as Zanzibar. Their range does not extend to Madagascar.
Galagos are all arboreal and known for their ability to leap great distances among branches.
Galagos are omnivorous but primarily insectivorous. Their favorite food is grasshoppers, but they also eat small birds, eggs, fruits, seeds and flowers. Euoticus has specialized front teeth for removing tree bark so it can feed on tree gum. Galagos typically feed at night alone or in small groups. During the day they sleep together in larger groups in nests made in tree forks, hollow trees or old bird nests.
