Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Mammalia
Order: Primates
Suborder: Strepsirrhini
Family: Galagidae
Genus: Galago
Species: Galago moholi

Geographic Range

Lesser bushbabies, Galago moholi, are found in the forested bush regions of Central Southern Africa. Their range does not extend to Madagascar. ()

Biogeographic Regions:
ethiopian (native ).

Habitat

Galago moholi is arboreal. This species lives in semiarid woodlands and savana grasslands. ()

These animals are found in the following types of habitat:
tropical ; terrestrial .

Terrestrial Biomes:
savanna or grassland ; scrub forest .

Physical Description

Mass
140 to 230 g; avg. 185 g
(4.93 to 8.1 oz; avg. 6.51 oz)


Length
88 to 210 mm
(3.46 to 8.27 in)


Basal Metabolic Rate


Lesser bushbabays are about the size of a small chipmunk. They are sexually monomorphic. They have a head and body length from 88 to 210 mm and tail length 180 to 303 mm. These animals weigh between 140 and 230 g when mature. They have soft, dense fur, and a grey coat with yellowish grey underside. Their lower incisors are elongated and form a tooth comb used in grooming. Their thumbs are not opposable.

Ears in the genus Galago are interesting because they have four transverse ridges, which serve as flexing points in bending the ear in different directions, allowing each ear to be furled and unfurled, presumably assisting in detection of noises. ()

Some key physical features:
endothermic ; bilateral symmetry .

Reproduction

Breeding interval
Lesser bush babies breed every four to eight months.

Breeding season
These animals breed throughout the year.

Number of offspring
1 to 2

Gestation period
123 days (average)

Birth Mass
10.60 g (average)
(0.37 oz)
[External Source: AnAge]


Time to weaning
3.50 months (average)

Age at sexual or reproductive maturity (female)
9 to 12 months

Age at sexual or reproductive maturity (male)
9 to 12 months

Within the genus Galago, males occupy ranges overlapping those of several females. There is fierce competition for these ranges. However, some reports indicate that these animals live in small family groups, including a male, a female, and their offspring. These factors suggest that members of the genus are polygynous and/or monogamous. ()

Mating systems:
monogamous ; polygynous .

Lesser bushbabies reach sexual maturity at 9 to 12 months of age, and mate every 4 to 8 months. Gestation lasts about 123 days and they usually have one or two offspring.

At birth, these animals weigh about 9.5 g. Although they are fully furred and have eyes open at birth, they do not leave the nest for the first 10 to 11 days of their lives. Mothers nurse their young for the first three and one-half months, though they begin to eat solid food after the first month. ()

Key reproductive features:
iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; viviparous .

Mothers construct a nest for their young before birth. Young remain in the nest while the mother searches for food. Young begin to walk and make short leaps after about two weeks. Females nurse their young for about three and a half months.

The role of males in parental care is not well documented. Because males defend the territory surrounding the female's nest from other males, they may play some role in defense of the young. ()

Parental investment:
altricial ; pre-fertilization (provisioning, protecting: female); pre-hatching/birth (provisioning: female, protecting: female); pre-weaning/fledging (provisioning: female, protecting: male, female); pre-independence (protecting: male, female).

Lifespan/Longevity

Average lifespan (captivity)
16.60 years
[External Source: AnAge]


Another member of the genus, Galago senegalensis, is reported to have reached a maximum age of nearly 19 years in captivity. Galago moholi is probably similar. ()

Behavior

Galago moholi is an arboreal, nocturnal forager. They are typically solitary, although they may live in small or in groups of 2 or 3 individuals. These groups may include a mother and offspring, or may include an adult male. During the day these galagos sleep in nests made in hollow trees or abandoned bird nests.

Unlike other galagines, members of the genus Galago inhabit open woodlands, savannahs, and thickets in grassland habitats. Within the homerange, G. moholi may make use of one of several favorite resting places during the day, as well as for a midnight resting period.

Locomotion is mainly by hopping, and rarely involves true quadrupedal locomotion, although these animals are capable of that. Galagos make long leaps through the trees, and can cover about 2.1 km in a single night. ()

Home Range

The size of home ranges differs between males and females. Males utilize home ranges of 1.5 to 22.9 hectares, whereas females use ranges of 4.4 to 11.7 hectares. In good habitats, densities of animals was between 95 and 200 per square km. ()

Communication and Perception

Galagos are highly vocal. They are reported to use scent marking and other chemical communication. Males are reported to "wash" their hands and feet in their own urine, allowing them to leave a scent trail where ever they move, although this behavior may also help to improve their grip on branches. As in other primates, tactile communication is of some importance, especially between mothers and their offspring, as well as between mates. Mutual licking and grooming has been reported in galago species. ()

Communicates with:
tactile ; acoustic ; chemical .

Other communication keywords:
pheromones ; scent marks .

Perception channels:
visual ; tactile ; acoustic ; chemical .

Food Habits

Galago moholi is a primarily insectivorous omnivore. They prefer grasshoppers, butterflies, and moths, but they also eat fruits, seeds, and flowers. They sometimes feed on tree gums and saps. ()

Primary Diet:
omnivore .

Animal Foods:
insects.

Plant Foods:
seeds, grains, and nuts; fruit; flowers; sap or other plant fluids.

Predation

Although details on predation of these animals were not available in the references examined, it is likely that these small, nocturnal primates fall prey to any number of smaller carnivorous species. Likely predators include small felids, herpestids, mustelids, raptors, and snakes.

Because galagos are such good leapers, one might expect them to use this form of locomotion to evade predators.

Ecosystem Roles

As insect predators, these animals may provide some control of insect populations. As frugivores, they may help to disperse seeds. As potential prey animals, they may have some positive effect on their predators.

Key ways these animals impact their ecosystem:
disperses seeds.

Economic Importance for Humans: Negative

Although no negative impacts have been reported for these primates, other similar galagos are known to harbor viruses that affect humans. It is likely that G. moholi also carries some human diseases, although this is speculative. ()

Economic Importance for Humans: Positive

These animals have no known positive economic impact on humans.

Conservation Status

IUCN Red List: [link]:
Lower Risk - Least Concern.

US Federal List: [link]:
No special status.

CITES: [link]:
Appendix II.

Population estimates in the wild are unknown, however, the largest threat is loss of habitat due to land clearing.
