Geographic Range
Liberian mongooses (
Liberiictis kuhni
) have historically been found in northeastern Liberia and western Côte d’Ivoire.
However, a small population was discovered in southeastern Liberia in 2011, about
80 km south of their previously known home range. Currently, their range reaches south
to the Sapo National Park in Liberia and north as far as southern Guinea, when suitable
habitat is available. They range west to central Liberia and east to western Côte
d’Ivoire, all along the border of Liberia.
Habitat
The natural habitat of Liberian mongooses is primary, undisturbed forests and secondary
forests which have experienced past effects of disturbance. They have also been found
in and around stream beds with sandy soils, as well as in freshwater swamp forests.

Physical Description
Liberian mongooses have dark brown coats with distinctive dark stripes on the sides
of their necks, bordered by two white stripes. They have pale-colored throats, dark
legs, and slightly bicolored bushy tails. Compared to other mongooses, distinguishing
features of Liberian mongooses include elongated snouts, sharp canines with an additional
premolar in both the upper and lower jaws. They use their elongated snouts to dig
up insects, which is their primary food source. The average body length of adult males
is 42.3 cm long, with an average tail length of 19.7 cm. The average body length of
adult females is 47.8 cm long, with an average tail length of 20.5 cm. The average
weight of adult males and females is 2 kg. Liberian mongooses have long, thick claws
used for digging up food. The longest claws on their hind feet are located on their
third and fourth toes, and reach up to 13 mm. The longest claws on their forefeet
can reach 18 mm. When comparing Liberian mongooses to their close relatives, common
kusimanses (
Crossarchus obscurus
), Liberian mongooses have a much larger and robust skull. Their teeth are proportionally
smaller and weaker than common kusimanses. Liberian mongooses also have dark stripes
along the back of their necks, and they have longer ears than common kusimanses.

- bilateral symmetry
- Sexual Dimorphism
- sexes alike
Reproduction
The mating system of Liberian mongooses is not well documented. However, one of their
closest relatives, banded mongooses (
Mungos mungo
), live in groups of males and females, with one dominant male being aggressive to
all other males who attempt to mate. However, this does not stop females from mating
with other males in the group. During courtship, females participate by lying on their
backs and wrestling with males.
Little is known about the reproductive behaviors of Liberian mongooses. It is thought that their breeding season coincides with the rainy season, which is from May to September.
A close relative of Liberian mongooses - banded mongooses (
Mungos mungo
) - have a gestation period typically around two months. Their young are born nearly
hairless and blind. Litters are born in burrows with grass lining and multiple chambers.
Females become sexually mature around 9 to 10 months old, and males as early as 4
months old.
- Key Reproductive Features
- iteroparous
- seasonal breeding
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual
- fertilization
- viviparous
Parental investment in Liberian mongooses is unknown.
Their close relatives, banded mongooses (
Mungos mungo
), have litters of 2 to 6 pups. Young may be suckled by any lactating female, not
just their mothers. At four weeks old, pups are allowed out of their dens accompanied
by an adult. At three months old, pups are independent. The whole pack participates
in the raising young.
Lifespan/Longevity
Little is known about the lifespan of Liberian mongooses. However, the IUCN lists
their generational length to be about four years.
Behavior
There has been limited research on the behavior of Liberian mongooses. They are known
to be most active diurnally and they are a ground dwelling species. Liberian mongooses
use burrows - most typically tree holes. There has also been one instance of a burrow
associated with a termite mound. These burrows are assumed to be used as their den
for resting and raising their young. Typically, 3 to 5 individuals occupy a single
burrow, and groups as large as 15 individuals have been reported foraging together.
Home Range
Little is known about the home range of Liberian mongooses.
Communication and Perception
Communication habits of Liberian mongooses are not well documented.
One of their closest relatives, banded mongooses (
Mungos mungo
), have been documented to have 15 different acoustically discrete call types. They
live in social groups and coordination of behaviors and decisions within that group
is essential. Banded mongooses also use scent marking to mark their territory, and
to mark each other in case of separation.
Food Habits
Liberian mongooses uses their elongated snouts and long claws to dig through sand
and soil in search of food. Liberian mongooses are primarily insectivorous, but they
also eat worms, eggs, and small vertebrates. It was reported that a captive Liberian
mongoose was fed fish, young chicken, dog food, and ground meat. Liberian mongooses
are most often found foraging around stream beds with deep, sandy soils where an abundance
of earthworms, a primary food source, can be found.

Predation
Natural predators of Liberian mongooses are not documented, and humans are believed
to be their primary predator. They are hunted for their meat using shotguns, snares,
and dogs.
Ecosystem Roles
Liberian mongooses are thought to be ecosystem engineers, by increasing small-scale
ecosystem heterogeneity. They affect seed predation and assist in seed dispersal and
germination. They are known to aid their ecosystems by turning over large areas of
the forest while foraging. This mixes organic matter into the soil and encourages
fresh plant growth.
- Ecosystem Impact
- disperses seeds
- soil aeration
Economic Importance for Humans: Positive
The only economic importance of Liberian mongooses for humans is as a food source.

Economic Importance for Humans: Negative
Liberian mongooses have no documented negative economic impact on humans.
Conservation Status
The IUCN Red List of Threatened Species has listed Liberian mongooses as vulnerable.
Liberian mongooses were thought to only inhabit northeastern Liberia and western Côte
d’Ivoire. However, in 2011 they were spotted in Sapo National Park, in southeastern
Liberia. Liberian mongoose populations are currently declining, with an estimated
population of mature individuals being 5,200. The main cause for their decline is
human hunting and habitat loss due to logging, mining, and agriculture.
Other Comments
There has been limited research done on Liberian mongooses because they are rare and difficult to study. This is why very little is known about their behavior.
Liberian mongooses were first described in 1958 based only on a skull bone. In 1974,
the first complete specimen was secured, but it was not until 1989 that a live specimen
was captured. Studies on these specimens have provided information into the morphology
of Liberian mongooses more than their behavior. Most of what we know behaviorally
comes from a few observations by scientists, as well as local accounts from human
observers. A live specimen was exhibited at the Toronto Zoo in 1989, but has since
died, leaving no documented live specimen in captivity currently.
