Galago
Characteristics

Galagos have large eyes that give them good night vision in addition to other characteristics, like strong hind limbs, acute hearing, and long tails that help them balance. Their ears are bat-like and allow them to track insects in the dark. They catch insects on the ground or snatch them out of the air. They are fast, agile creatures. As they bound through the thick bushes, they fold their delicate ears back to protect them. They also fold them during rest. They have nails on most of their digits, except for the second toe of the hind foot, which bears a grooming claw. Their diet is a mixture of insects and other small animals, fruit, and tree gums. They have pectinate (comb-like) incisors called toothcombs, and the dental formula: 2.1.3.3 2.1.3.3 They are active at night.

After a gestation period of 110–133 days, young galagos are born with half-closed eyes and are initially unable to move about independently. After a few (6–8) days, the mother carries the infant in her mouth, and places it on branches while feeding. Females may have singles, twins, or triplets, and may become very aggressive. Each newborn weighs less than one-half ounce (14 g). For the first three days, the infant is kept in constant contact with the mother. The young are fed by the mother for six weeks and can feed themselves at two months. The young grow rapidly, often causing the mother to walk awkwardly as she transports them.

Females maintain a territory shared with their offspring, while males leave their mothers' territories after puberty. Thus social groups consist of closely related females and their young. Adult males maintain separate territories, which overlap with those of the female social groups; generally, one adult male mates with all the females in an area. Males that have not established such territories sometimes form small bachelor groups.

Bush-babies are sometimes kept as pets, although this is not advised because, like many other nonhuman primates, they are a likely sources of diseases that can cross species barriers. Equally, they are very likely to attract attention from customs officials on importation into many countries. Reports from veterinary and zoological sources indicate captive lifetimes of 12.0 to 16.5 years, suggesting a natural lifetime over a decade.

Galagos communicate by calling to each other and by marking their paths with urine. By following the scent of urine, they can land on exactly the same branch every time. Each species produces a unique set of loud calls that have different functions. One function is to identify individuals as members of a particular species across distances. Scientists can recognize all known galago species by their 'loud calls'. At the end of the night, group members use a special rallying call and gather to sleep in a nest of leaves, a group of branches, or a hole in a tree.
