The
honey badger (
Mellivora capensis), also known as the
ratel (
or
),
[3] is the only species in the
mustelid subfamily
Mellivorinae and its only genus
Mellivora. It is native to
Africa,
Southwest Asia, and the
Indian subcontinent. Despite its name, the honey badger does not closely resemble other
badger species; instead, it bears more anatomical similarities to
weasels. It is classed as
Least Concern by the
IUCN owing to its extensive range and general environmental adaptations. It is primarily a
carnivorous species and has few natural
predators because of its thick skin and ferocious defensive abilities.
Taxonomy
The honey badger is the
only species of the
genus Mellivora. Although in the 1860s it was assigned to the badger subfamily, the
Melinae, it is now generally agreed that it bears very few similarities to the Melinae. It is much more closely related to the
marten subfamily,
Mustelinae, but furthermore is assigned its own subfamily,
Mellivorinae.
[4]
Differences between Mellivorinae and Melinae include differences in
their dentition formulae. Though not in the same subfamily as the
wolverines,
which are a genus of large-sized and atypical Mustelinae, the honey
badger can be regarded as another, analogous, form of outsized
weasel or
polecat.
The species first appeared during the middle
Pliocene in Asia. Its closest relation was the
extinct genus
Eomellivora, which is known from the upper
Miocene, and evolved into several different species throughout the whole Pliocene in both the
Old and
New World.
[5]
Subspecies
As of 2005, 12 subspecies are recognised.
[6]
Points taken into consideration in assigning different subspecies
include size and the extent of whiteness or greyness on the back.

Physical description
The honey badger has a fairly long body, but is distinctly thick-set
and broad across the back. Its skin is remarkably loose, and allows it
to turn and twist freely within it.
[12] The skin around the neck is 6 millimetres (0.24 in) thick, an adaptation to fighting
conspecifics.
[13] The head is small and flat, with a short muzzle. The eyes are small, and the ears are little more than ridges on the skin,
[12] another possible adaptation to avoiding damage while fighting.
[13]
The honey badger has short and sturdy legs, with five toes on each
foot. The feet are armed with very strong claws, which are short on the
hind legs and remarkably long on the forelimbs. It is a partially
plantigrade animal whose
soles are thickly padded and naked up to the
wrists. The
tail is short and is covered in long hairs, save for below the base.
Honey badgers are the largest terrestrial mustelids in Africa. Adults
measure 23 to 28 cm (9.1 to 11.0 in) in shoulder height and 55–77 cm
(22–30 in) in body length, with the tail adding another 12–30 cm
(4.7–11.8 in). Females are smaller than males.
[12][14]
Males weigh 9 to 16 kg (20 to 35 lb) while females weigh 5 to 10 kg (11
to 22 lb) on average. Skull length is 13.9–14.5 cm (5.5–5.7 in) in
males and 13 cm (5.1 in) for females.
[15][16]
There are two pairs of
mammae.
[17] The honey badger possesses an anal pouch which, unusual among mustelids, is eversible,
[18] a trait shared with
hyenas and
mongooses. The smell of the pouch is reportedly "suffocating", and may assist in calming
bees when raiding beehives.
[19]
The
skull bears little similarity to that of the
European badger, and greatly resembles a larger version of that of a
marbled polecat.
[20] The skull is very solidly built, with that of adults having no trace of an independent bone structure. The
braincase is broader than that of
dogs.
The
dental formula is:
3.1.3.13.1.3.1.
The teeth often display signs of irregular development, with some teeth
being exceptionally small, set at unusual angles or are absent
altogether. Honey badgers of the subspecies
signata have a second
lower molar on the left side of their jaws, but not the right. Although
it feeds predominantly on soft foods, the honey badger's cheek teeth
are often extensively worn. The
canine teeth are exceptionally short for carnivores.
[21] The
tongue has sharp, backward-pointing
papillae which assist it in processing tough foods.
[22]
The winter fur is long (being 40–50 mm (1.6–2.0 in) long on the lower
back), and consists of sparse, coarse, bristle-like hairs lacking
underfur.
Hairs are even sparser on the flanks, belly and groin. The summer fur
is shorter (being only 15 mm (0.59 in) long on the back) and even
sparser, with the belly being half bare. The sides of the heads and
lower body are pure black. A large white band covers their upper bodies,
beginning from the top of their heads down to the base of their tails.
[23] Honey badgers of the
cottoni subspecies are unique in being completely black.
[9]
Behaviour
Habits
Although mostly solitary, honey badgers may hunt together in pairs during the May
breeding season.
[22] Little is known of the honey badger's breeding habits. Its
gestation period
is thought to last six months, usually resulting in two cubs, which are
born blind. They vocalise through plaintive whines. Its
lifespan in the wild is unknown, though captive individuals have been known to live for approximately 24 years.
[7]
Honey badgers live alone in self-dug holes. They are skilled diggers,
able to dig tunnels into hard ground in 10 minutes. These burrows
usually have only one passage and a nesting chamber and are usually only
1–3 m (3–10 ft) long. They do not place bedding into the nesting
chamber.
[24] Although they usually dig their own burrows, they may take over disused
aardvark and
warthog holes or
termite mounds.
[22]
Honey badgers are intelligent animals and are one of a few species
known to be capable of using tools. In the 1997 documentary series
Land of the Tiger, a honey badger in India was filmed making use of a tool; the animal rolled a log and stood on it to reach a
kingfisher fledgling stuck up in the roots coming from the ceiling in an underground cave.
[25]
A video made at the Moholoholo rehab centre in South Africa showed a
pair of honey badgers using sticks, a rake, heaps of mud and stones to
escape from their walled pit.
[26]
As with other mustelids of relatively large size, such as
wolverines and
badgers,
honey badgers are notorious for their strength, ferocity and toughness.
They have been known to savagely and fearlessly attack almost any kind
of animal when escape is impossible, reportedly even repelling much
larger predators such as
lions.
[27] Bee stings, porcupine quills, and animal bites rarely penetrate their skin. If
horses,
cattle, or
Cape buffalos
intrude upon a ratel's burrow, it will attack them. They are virtually
tireless in combat and can wear out much larger animals in physical
confrontations.
[21] The aversion of most predators toward hunting honey badgers has led to the theory that the countershaded coats of
cheetah cubs evolved in imitation of the honey badger's colouration to ward off predators.
[28]
The voice of the honey badger is a hoarse "khrya-ya-ya-ya" sound. When mating, males emit loud grunting sounds.
[29] Cubs vocalise through plaintive whines.
[7] When confronting dogs, honey badgers scream like
bear cubs.
[30]
Diet
Next to the
wolverine, the honey badger has the least specialised diet of the weasel family.
[13] In undeveloped areas, honey badgers may hunt at any time of the day, though they become
nocturnal in places with high human populations. When hunting, they trot with their foretoes turned in. Honey badgers favour bee
honey,
and will often search for beehives to get it, which earns them their
name. They are also carnivorous and will eat insects, frogs, tortoises,
rodents, turtles, lizards, snakes, eggs, and birds. Honey badgers have
even been known to chase away young
lions and take their kills. They will eat fruit and vegetables, such as
berries,
roots and
bulbs.
[22] Despite popular belief, there is no evidence that
honeyguides (a bird species that eats bee larvae) guide the honey badger.
[31][32]
They may hunt frogs and rodents, such as
gerbils and
ground squirrels,
by digging them out of their burrows. Honey badgers are able to feed on
tortoises without difficulty, due to their powerful jaws. They kill and
eat snakes, even highly venomous or large ones, such as
cobras. They have been known to dig up human corpses in India.
[33]
They devour all parts of their prey, including skin, hair, feathers,
flesh and bones, holding their food down with their forepaws.
[34] When seeking vegetable food, they lift stones or tear bark from trees.
[22]
Range
The species ranges through most of
sub-Saharan Africa, from the
Western Cape,
South Africa, to southern
Morocco and southwestern
Algeria and outside
Africa through
Arabia,
Iran and western
Asia to
Turkmenistan and the
Indian Peninsula. It is known to range from sea level to as much as 2,600 m above sea level in the Moroccan
High Atlas and 4,000 m in
Ethiopia's
Bale Mountains.
[1]
Relationships with humans
Honey badgers often become serious poultry predators. Because of
their strength and persistence, they are difficult to deter. They are
known to rip thick planks from hen-houses or burrow underneath stone
foundations.
Surplus killing is common during these events, with one incident resulting in the death of 17
Muscovy ducks and 36
chickens.
[22]
Because of the toughness and looseness of their skin, honey badgers
are very difficult to kill with dogs. Their skin is hard to penetrate,
and its looseness allows them to twist and turn on their attackers when
held. The only safe grip on a honey badger is on the back of the neck.
The skin is also tough enough to resist several
machete
blows. The only sure way of killing them quickly is through a blow to
the skull with a club or a shot to the head with a gun, as their skin is
almost impervious to
arrows and
spears.
[35]
During the British occupation of
Basra
in 2007, rumours of "man-eating badgers" emerged from the local
population, including allegations that these beasts were released by the
British troops, something that the British categorically denied.
[36][37]
A British army spokesperson said that the badgers were "native to the
region but rare in Iraq" and "are usually only dangerous to humans if
provoked".
[38]
The director of Basra's veterinary hospital, Mushtaq Abdul-Mahdi,
confirmed that honey badgers had been seen in the area as early as 1986.
The deputy dean of Basra's veterinary college, Dr. Ghazi Yaqub Azzam,
speculated that "the badgers were being driven towards the city because
of flooding in marshland north of Basra."
[37] The event received coverage in the Western press during the 2007
silly season.
[39]
In many parts of North India, honey badgers are reported to have been
living in the close vicinity of human dwellings, leading to many
instances of attacks on poultry, small livestock animals and, sometimes,
even children.
[citation needed] They retaliate fiercely when attacked.
[citation needed] According to a 1941 volume of
The Fauna of British India, the honey badger has also been reported to dig up human corpses in that country.
[40]
In
Kenya, the honey badger is a major reservoir of
rabies[41][42] and suspected to be a significant contributor to the
sylvatic cycle of the disease.
[43]
In popular culture
The viral video
Crazy Nastyass Honey Badger became popular in 2011, attaining over 80 million views on
YouTube as of October 2016. The video features footage from the
Nat Geo WILD network of honey badgers fighting
jackals, invading
beehives, and eating
cobras, with a voiceover added by the uploader, "Randall".
[44] Randall subsequently published the book
Honey Badger Don't Care in the same year. The video has been referenced in an episode of the popular television series
Glee and commercials for the video game
Madden NFL 12 and
Wonderful Pistachios.
[45] The video has also influenced references to honey badgers on the show
American Pickers.
[46] A honey badger in Disney Junior's show
The Lion Guard, shows a honey badger named Bunga.
