Subfamily: Viverrinae
Genus: Genetta

Geographic Range

Angolan genets occur in a narrow band across southern Africa from the Atlantic to the Indian Ocean between 5 and 15 degrees S latitude. (Haltenorth and Diller, 1980)

Biogeographic Regions:
ethiopian (native ).

Habitat

Rain forests and moist savannahs (Haltenorth & Diller 1980, Estes 1991).

Terrestrial Biomes:
savanna or grassland ; rainforest .

Physical Description

Mass
1 to 2 kg
(2.2 to 4.4 lbs)


The Angolan genet is a cat-sized carnivore with a small head on a long, slender body with relatively short legs and a long tail. Genets have large eyes and blunt, triangular ears of medium size. Fore and hind feet have five digits equipped with short, sharp claws that are curved and semi-retractile. The soles of the feet are furred between the digital and plantar pads. Hindfeet are further equipped with long, narrow metatarsal pads. There are four teats and the males have a well-developed baculum. Both sexes have paired anal and perineal glands. Genets have 40 teeth with a tooth formula of 3/3 1/1 4/4 2/2; the molars are broad and relatively unspecialized. Males may be slightly larger and heavier than females.

The pelage of the Angolan genet is a dark gray or dark reddish-gray background with black to brownish-black spots in a complex, symmetrical pattern. On the neck and back are round or elongate dark brown to black spots forming five longitudinal rows on either side of the dark dorsal crest. The upper two rows of spots may blend together, and the lower rows are often imperfect. Separate spots continue down the proximal portion of each limb. The underside of the body is paler gray and unspotted. The undersides of the fore and hindfeet (to the heel) are grayish-black to black. The spinal hair crest of G. angolensis is relatively long (up to 6 cm) and erectile. The tail is more thickly furred than in other species of Genetta and sports a black underside and eight black rings. The tail tip may be light, or the last black tail ring may merge into a black tip. Angolan genets have a dark gray face with a slightly paler supra-orbital spot. The sub-orbital region, front of the upper lip, and chin are white, while the back of the upper lip and dorsal surface of the nose are black. There is also a black stripe from the middle of the forehead that is continuous with the black spinal crest. Very dark or melanistic individuals are not uncommon. (Estes, 1991; Ewer, 1973; Haltenorth and Diller, 1980)

Some key physical features:
endothermic ; homoiothermic; bilateral symmetry .

Reproduction

Details unknown. Presumed to be similar to G. genetta with the range of single male overlapping that of several females, and from 1-2 reproductive cycles per year depending upon latitude. Males and females probably come together only for breeding, with 1-4 young born helpless and blind in a burrow or tree cavity after a gestation period of 70-77 days. (Estes, 1991; Haltenorth and Diller, 1980)

Key reproductive features:
iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous .

Behavior

Details unknown. Presumed to be similar to G. genetta in being nocturnal, resting by day in hiding places among rocks, in trees, or in ground burrows. Angolan genets are forest-dwellers and therefore probably largely arboreal. All Genetta species are skilled leapers and climbers, deftly performing head-first descents. Sense of smell is excellent, and sight is especially well-developed to perceiving movement under low-light conditions. Defecation is at regular latrines. Anal sacs are used to mark objects, often while performing a handstand. Defensive postures include erecting hair along the spinal crest while arching the back. Hair on the tail is also erectile and is often arched over the body making the animal appear larger. Under extreme circumstances, genets will hiss, spit, and emit foul-smelling anal secretions. They often seek refuge in trees. (Estes, 1991; Haltenorth and Diller, 1980)

Key behaviors:
arboreal ; nocturnal ; motile .

Food Habits

Details unknown. Presumed to be similar to G. genetta in being a generalized predator, taking a wide variety of small vertebrate and invertebrate prey. May also eat fruit and carrion. (Estes, 1991; Haltenorth and Diller, 1980)

Primary Diet:
carnivore (eats terrestrial vertebrates, insectivore ).

Economic Importance for Humans: Negative

Details for this species unknown. Other species of Genetta are known to occasionally attack and kill poultry. (Haltenorth and Diller, 1980)

Economic Importance for Humans: Positive

Details for this species unknown. However, as important predators on small vertebrates including rodents, Genetta spp. are often tolerated around farms and towns and even kept as pets in some areas. (Macdonald, 1984)

Ways that people benefit from these animals:
controls pest population.

Conservation Status

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

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

CITES: [link]:
No special status.

The classification of genets (genus Genetta), particularly allocation to subspecies, is uncertain, so the status of different groups is also uncertain. The Angolan genet may be relatively common within its range, however the habitats known to be important to this species are shrinking due to human land-use practices which include logging, farming, and grazing of livestock in lands set aside for wildlife . (Haltenorth and Diller, 1980)

Other Comments

Genets are believed to closely resemble the miacid ancestors to the Carnivora, with dental and skeletal characteristics that have changed little over the past 40-50 million years. Genets are the only species within the family Viverridae that stand bipedally. (Estes, 1991; Ewer, 1973)
