Geographic Range
Hog badgers are distributed primarily in Southeast Asia, starting from Sikkim and
northeastern China to Thailand. They are found on the Indian subcontinent and the
island of Sumatra. Hog badgers do not appear to be migratory from winter to summer.
They are also native to both the Palearctic and Oriental regions. There was no evidence
suggesting that they are an introduced species.

Hog badgers are found in grasslands, hills, mountains, tropical rainforests, tropical
evergreen, and semi-evergreen forests.

Physical Description
Their fur color ranges from a dark grey to brown, while tail color ranges from white
to a light yellow. Two dark stripes are found on the face, and the throat is white
in color. The most notable feature is the "pig-like snout" that is used for feeding,
along with modified teeth specifically used to move soil. Tail lengths range from
12 cm to 17 cm (120 mm to 170 mm). Another notable feature used to distinguish hog
badgers from the closely related
Eurasian badgers
is the color of their claws. Hog badgers have light-colored claws whereas Eurasian
badgers have dark claws. To distinguish between hog badgers,
Sumatran hog badgers
, and
northern hog badgers
, there is a difference in skull shape and size. No information was found on the
basal metabolic rate of hog badgers. However, Eurasian badgers (a closely related
group), have a basal metabolic rate of 1,323 kJ per day. Also, there was little information
on sexual dimorphism in hog badgers other than males are larger than females.

- bilateral symmetry
- Sexual Dimorphism
- male larger
Reproduction
There is little information known on the mating system for hog badgers. However, there
is some information about the
badgers, otters, weasels family
. Males begin their sexual seasons before the females, and therefore, initiate breeding.
This is often done by first obtaining territory.
The breeding period occurs from April to September, with the gestation period being
5 to 9.5 months long. Their litter size is 2 to 4 cubs. Although there is no information
known about the sexual maturity of the two sexes, the information about the
badgers, otters, weasels family
offers some insight about what might occur for hog badgers, as well. For the badgers,
otters, weasels family, females reach sexual maturity after 2 to 3 months, whereas
the males do not reach sexual maturity until they are a year old. Also, there is
little to know of the time of independence in hog badgers. However,
American badgers
(a similar species) have a time of independence of 5 to 6 months.
- Key Reproductive Features
- iteroparous
- seasonal breeding
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual
- viviparous
- delayed implantation
Females are the primary caretakers of the young, and wean them for up to 4 months.
Currently no information is available regarding specifics of parental care.
- Parental Investment
- female parental care
- pre-fertilization
- pre-hatching/birth
- pre-weaning/fledging
- pre-independence
Lifespan/Longevity
There is no information known for the lifespan of hog badgers in the wild. However,
in captivity the average lifespan is 14 years old.
Behavior
Hog badgers are a motile solitary species, meaning they are found to travel by themselves.
They are also active at night (nocturnal). Hog badgers often burrows into the ground
(fossorial) to find food or to create a habitat.
Home Range
Hog badger home ranges describe a smaller section of the geographical range where
it can find a sustaining food source and shelter. Although, there is no known information
about the exact territory size of hog badgers,
Eurasian badger
females have a home range of 12.4 sq km.
Communication and Perception
There is no information known about the communication patterns for hog badgers. However,
it is suggested that tactile communication and communication via scents may be used
as seen in other species of belonging to the
badgers, otters, weasels
family.
Food Habits
Hog badgers feed on a variety of things based on what is available ranging from plants
to worms to small mammals. It is therefore considered an omnivore. It is able to find
food using its adapted pig like snout to sense smells. They dig in the ground using
their snout, incisors, and canine teeth of their lower jaws. They will also eat fruit,
roots and tubers. Its favorite food appears to be terrestrial earthworms.

Predation
Hog badgers are well suited predators as they possess big claws, strong jaws, flexible
skin and nasty tempers. Their coloration pattern is aposematic, meaning it has distinct
coloration or patterns to warn other organisms it is dangerous and should be left
alone. Hog badgers are great diggers, and can dig out of sight if it feels threatened.
Also, they can produce secretions from their anal glands, but it is unknown whether
or not that is a defense mechanism. Their only known predators are
tigers
and
leopords
.
- Anti-predator Adaptations
- aposematic
Ecosystem Roles
There is little to no known information on the impact of hog badgers on their surrounding
ecosystem. However, due to their foraging behaviors, they play some role in controlling
the populations of invertebrates. Also, they aerate the soil by digging. Another interesting
role they play is creating a habitat for other small animals through abandoned hog
badger burrows.
- Ecosystem Impact
- creates habitat
- soil aeration
- palm civets ( Paradoxurus Hermaphroditus )
- sables ( Martes zibellina )
- SARS-CoV-like virus
Economic Importance for Humans: Positive
There is little known evidence to suggest a positive benefit to humans from hog badgers.
However, some groups in India eat hog badgers, and they are hunted and farmed for
food in China. In Lao, taste preference for hog badgers varies among ethnic groups.
Some groups do not care for their meat, whereas groups in parts of the Nam Theun basin
seek them for food.
- Positive Impacts
- food
Economic Importance for Humans: Negative
There is no known adverse effects of hog badgers on humans. However, its relatives,
Eurasian badgers
, have been known to carry bovine tuberculosis. There is a possibility that hog badgers
could also carry diseases common to livestock. Hog badgers and
Eurasian badgers
have a similar diet and have been known to damage crops.
- Negative Impacts
- crop pest
- causes or carries domestic animal disease
Conservation Status
Hog badgers, in 1996, were listed least concerned. However, their population is decreasing,
and they are currently listed as near threatened. In Thailand and India, they are
under high protected statuses under law. They are threatened due to the use of hunting
dogs in all of Indochina.
