Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Mammalia
Order: Carnivora
Suborder: Feliformia
Family: Herpestidae
Genus: Bdeogale
Species: Bdeogale nigripes

Geographic Range

Bdeogale nigripes lives in African rainforests, from southeastern Nigeria to northern Democratic Republic of the Congo and also northern Angola. (Nowak ,1999)

Biogeographic Regions:
ethiopian (native ).

Habitat

Black-legged mongooses live in dense African rainforests and are often found near rivers. (Rosevear, 1974)

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

Terrestrial Biomes:
rainforest .

Other:
riparian .

Physical Description

Mass
900 to 3000 g; avg. 1950 g
(31.68 to 105.6 oz; avg. 68.64 oz)


Length
375 to 600 mm; avg. 487.50 mm
(14.76 to 23.62 in; avg. 19.19 in)


The body of B. nigripes is long, ranging from 375 to 600 mm long with short limbs and a blunt muzzle. The tail is 175 to 375 mm long. Adult animals stand 150 to 175 mm at the shoulders. These mammals weigh between 900 and 3000 g.

The upper layer of fur on the black-legged mongoose is long and coarse with a soft, dense undercoat. The individual hairs are generally banded with colors ranging from white at the base to dark brown at the tip. Their predominant coat color is grayish-brown with black legs. Several molts can occur which progressively darken the color of the fur as the animal ages.

B. nigripes have 4 shallowly webbed digits with non-retractile claws. Scent glands are located in the anal region. The dental formula is: I 3/3, C 1/1, P 3-4/3-4, M 2/2 = 36 – 40. The dentition and skulls of B. nigripes are less specialized than the more carnivorous mustelids.

(Nowak, 1999; Rosevear, 1974)

Some key physical features:
endothermic ; bilateral symmetry .

Reproduction

Breeding season
Dry season

Number of offspring
1 (low)

The mating system and behavior of this species has not been characterized.

B. nigripes have 1 young per litter. Mating occurs during the dry season of West Africa and the young are born between November and January. (Nowak, 1999; Rosevear 1974)

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

Although the parental care of this species has not been described, it is reasonable to assume that the female nurses her young, as is the case for all mammals. Herpestids, in general, have altricial offspring, and the mother typically cares for them in some type of burrow or nest until they are able to move about with her. A female and her quarter-grown young were collected in Kenya in December. (Nowak, 1999)

Parental investment:
female parental care .

Lifespan/Longevity

Extreme lifespan (captivity)
15 years (high)

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


Captive black-legged mongooses have lived for 15 years. (Nowak 1999)

Behavior

Black-legged mongooses are nocturnal and primarily terrestrial. They are frequently seen in pairs, but adults are generally solitary. In spite of their solitary habit in the wild, adults can be kept together in captivity without hostility. (Ray and Sunquist , 2001; Nowak, 1999)

Key behaviors:
nocturnal ; motile ; solitary .

Food Habits

B. nigripes is primarily insectivorous, feeding on termites, ants, and beetles. They also consume snakes, small mammals and carrion. Captive animals often eat amphibians. They have jaw and dentition structure that suggests crushing abilities but lack any specialization for eating ants. (Ray and Sunquist, 2001; Rosevear, 1974)

Primary Diet:
carnivore (insectivore ).

Animal Foods:
mammals; amphibians; reptiles; insects.

Predation

With the exception of notes indicating that humans sometimes eat these animals, there is no information available on predation. It is reasonable to assume, however, that these animals sometimes fall victim to larger rainforest carnivores.

Ecosystem Roles

Next to nothing is known about the ecology of these animals. Because of their foraging habits, black-legged mongoose populations probably have a negative impact on populations of invertebrates and small mammals on which they feed.

Economic Importance for Humans: Negative

B. nigripes is often introduced to kill poisonous snakes and rodents but they often kill desirable species of birds and mammals. (Nowak, 1999)

Economic Importance for Humans: Positive

The black-legged mongoose is a source of food in some northeastern African villages. (Ntiamoa – Baidu , 1997)

Ways that people benefit from these animals:
food .

Conservation Status

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

US Migratory Bird Act: [link]:
No special status.

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

CITES: [link]:
No special status.

Although no special conservation status for this animals has been reported, because it dwells in the rainforest, a threatened habitat, it is at risk from habitat destruction and human encroachment.

Other Comments

B. nigripes was formerly placed in the genus Galeriscus. (GIS Lab, date unknown)
