The leopard (Panthera pardus) is an Old World mammal of the Felidae family and the smallest of the four 'big cats' of the genus Panthera, along
with the tiger, lion, and jaguar. Leopards that are melanistic, either all-black or very dark in coloration, are known
colloquially as Black Panthers.
Once distributed across southern Eurasia and Africa, from Korea to South Africa and Spain, it has disappeared from much of its
former range and now chiefly occurs in subsaharan Africa. There are fragmented populations in the Indian subcontinent, Indochina,
Malaysia, and western China. Despite the loss of range and continued population declines, the cat remains a least concern species;[1]
its numbers are greater than that of the other Panthera species, all of which face more acute conservation concerns.
The species' success owes in part to its opportunistic hunting
behaviour and its adaptability to a variety of habitats. The leopard consumes virtually any animal it can catch and ranges from
rainforest to desert. Its ecological role resembles that of the similarly-sized cougar in the
Americas. Physically, the spotted cat most closely resembles the jaguar, although it is of lighter build.
Etymology
Originally, it was thought that a leopard was a hybrid between a lion and a panther, and the leopard's common name derives from this belief; leo is the Greek and Latin word for lion (Greek leon, λέων) and
pard is an old term meaning panther. In fact, a "panther" can be any of several species of large felid. In North America, panther means cougar and in South America a panther is
a jaguar. Elsewhere in the world a panther is a leopard. Early naturalists distinguished between leopards and panthers not by colour (a common misconception), but by
the length of the tail — panthers having longer tails than leopards. It was one of the many species originally described, as
Felis pardus, by Linnaeus in his 18th century work, Systema Naturae.[2]
The generic component of its scientific designation, Panthera pardus, is often presumed to derive from Greek
pan- ("all") and ther ("beast"), but this may be a folk etymology. Although
it came into English through the classical languages, panthera is probably of East Asian origin, meaning "the yellowish
animal," or "whitish-yellow".[3]
Physical characteristics
The leopard is an agile and graceful predator. Alhough smaller than the other members of Panthera, the leopard is still
able to take large prey given a massive skull that well utilizes powerful jaw muscles.[4] Its body is comparatively long for a cat and its legs short.[5] Head and body length is between 90 and 190 cm, the tail
reaches 60 to 110cm. Shoulder height is 45 to 80 cm. Males are considerably larger than females and weigh 37 to 90 kg compared to
28 to 60 kg for females.[6]
Exceptionally large males of 90kg have been recorded in parts of the range, (e.g. Sri lanka) where lion and tiger have been
absent for a long period.
One of many spotted cats, a leopard may be mistaken for a cheetah or a jaguar. The leopard has rosettes rather than cheetah's simple spots, but they lack internal spots, unlike the jaguar. The
leopard is larger and less lanky than the cheetah but smaller than the jaguar. The leopard's black, irregular rosettes serve as
camouflage. They are circular in East Africa but tend to be square in southern Africa.[5]
Leopards have been reported to reach 21 years of age in captivity.[7]
Black Panthers
-
Particularly in mountainous areas and rain forests occurs a melanistic morph of the
leopard, the black panther. The black colour is heritable and caused by only one
recessive gene locus. In some regions, for example
on the Malayan Peninsula up to 50% of all leopards are black. In Africa black leopards
seem to be most common in the Ethiopian Highlands.
Biology and behavior
Graceful and stealthy, leopards are famous for their ability to go undetected. They are good, agile climbers, but cannot get
down from a tree headfirst, because they do not have the ankle flexibility—the only two cats that do are the Margay and the Clouded Leopard.

Along with climbing, they are strong swimmers but not as fond of water as tigers; for example, leopards will not normally lie
in water. They are mainly nocturnal but can be seen at any time of day and will even hunt during daytime on overcast days. In
regions where they are hunted, nocturnal behaviour is more common. These cats are solitary, avoiding one another. However, three
or four are sometimes seen together. Hearing and eyesight are the strongest of these cats' senses and are extremely acute.
Olfaction is relied upon as well, but not for hunting. When making a threat, leopards stretch their backs, depress their ribcages
between their shoulder blades so they stick out, and lower their heads (similar to domestic cats). During the day they may lie in
bush, on rocks, or in a tree with their tails hanging below the treetops and giving them away.
Diet and hunting
Leopards are opportunistic hunters. Although mid-sized animals are preferred, the leopard will eat anything from
dung beetles to 900 kg male giant elands.[4] Their diet consists mostly of ungulates and monkeys, but rodents,
reptiles, amphibians, birds and
fish are also eaten.[8] In fact, they hunt about 90 different species of animals. A solitary dog is a potential prey for leopards, although a pack of dogs can tree or drive off a leopard. In Africa, mid-sized
antelopes provide a majority of the leopard's prey, especially impala and
Thomson's gazelles.[9] In Asia the leopard preys on deer such as chitals and
muntjacs as well as various Asian antelopes and Ibex.
The leopard stalks its prey silently and at the last minute pounces on its prey and strangles its throat with a quick bite.
Leopards often hide their kills in dense vegetation or take them up trees,[9] and are capable of carrying animals up to three times their own weight
this way. Storing carcasses up trees keeps them away from other predators such as spotted
hyenas, jackals, tigers and lions, though the latter will occasionally be successful in climbing and fetching the leopard kills.[10]
One survey of nearly 30 research papers found preferred prey weights of 10 to 40 kgs, with
25 kg most preferred. Along with impala and chital, a preference for bushbuck and
common duiker was found. Other prey selection factors include a preference for prey in
small herds, in dense habitat, and those that afford the predator a low risk of injury.[11]
Leopard resting on a tree
Although most leopards will tend to avoid humans, people are occasionally targeted as prey. Most healthy leopards prefer wild
prey to humans, but cats who are injured, sickly or struggling with a shortage of regular prey often turn to hunting people and
may become habituated to it. In the most extreme cases, both in India, a leopard dubbed "the Leopard of Rudraprayag" is claimed
to have killed over 125 people and the infamous leopardess called "Panar Leopard" killed over 400 after being injured by a
poacher and thus being made unable to hunt normal prey. The "Leopard of
Rudraprayag" and the "Panar Leopard" were both killed by the legendary hunter
Jim Corbett. Man-eating leopards are considered bold and commonly enter human
settlements for prey, moreso than their lion and tiger counterparts. However because they can subsist on small prey and are less
dependent on large prey, leopards are less likely to turn to man-eating than either lions or tigers.
Reproduction
A male may follow a female who catches his attention. Eventually fighting for reproductive rights can take place. Depending on
the region, leopards may mate all year round (India and Africa) or seasonally during January to February (Manchuria and Siberia).
The estrous cycle lasts about 46 days and the female usually is in heat for 6–7 days.[12] Cubs are usually born in a litter of 2–3, but infant mortality is high and
mothers are not commonly seen with more than 1–2 cubs. The pregnant females find a cave, crevice among boulders, hollow tree, or
thicket to give birth and make a den. Cubs open their eyes after a period of 10 days. The fur of the young tends to be longer and
thicker than that of adults. Their pelage is also more gray in color with less defined spots. Around three months the infants
begin to follow the mother out on hunts. At one year of age leopard young can probably fend for themselves but they remain with
the mother for 18–24 months.
Social structure and home range
Studies of leopard home range size have tended to focus on protected areas, which may have led to skewed data; as of the
mid-1980s, only 13% of the leopard range actually fell within a protected area.[13] In their IUCN survey of the literature, Nowell and Jackson suggest male
home territories vary between 30-78 square kilometers, but just 15-16 km² for
females.[4] Research in a conservation area in Kenya
shows similar territory sizes and sex differential: 32.8 km² ranges for males, on average, and 14 km² for females.[14] In Nepal, somewhat larger male ranges have been found at about
48 km², while female ranges are in-keeping with other research, at 17 km²; female home territories were seen to decrease to just
five to seven km² when young cubs were present, while the sexual difference in range size seemed to be in positive proportion to
overall increase.[15] However, significant variations in
size of home territories have been suggested across the leopard's range. In Namibia, for instance, research that focussed on
spatial ecology in farmlands outside of protected areas found ranges that were consistently above 100 km², with some more than
300 km²; admitting that their data were at odds with others', the researchers also suggested little or no sexual variation in the
size of territories.[13] Virtually all
sources suggest that males do have larger ranges. There seems to be little or no overlap in territory amongst males, although
overlap exists between the sexes; one radio-collar analysis in the Ivory Coast found a
female home range completely enclosed within a male's.[16]
The leopard is solitary and, aside from mating, interactions between individuals appear to be infrequent.[16] Aggressive enounters have been observed, however.
Two of five males studied over a period of a year at a game reserve in South Africa died, both violently. One was initially
wounded in a male-male territorial battle over a carcass; taken in by researchers, it was released after a successful
convalescence only to be killed by a different male a few months later. A second was killed by another predator, possibly a
spotted hyena. A third of the five was badly wounded in intraspecific fighting, but
recovered.[17]
Distribution and habitat
As of 1996, the leopard had the largest distribution of any wild cat,[4] although populations before and since have shown a declining trend and are fragmented outside of
subsaharan Africa. The IUCN notes that within subsaharan Africa the species is "still numerous and even thriving in marginal
habitats" where other large cats have disappeared, but that populations in North Africa may be extinct. In Asia, data on
distribution are mixed: populations in Southwest and Central Asia are small and fragmented; in the northeast portion of the
range, they are critically endangered; and in Indian, Southeast Asia, and China, the cat is still relatively abundant.[1]

It has been suggested that there may be as many as 30 extant subspecies of the Leopard. However, modern taxonomic analyses

Variant Coloration
A pseudo-melanistic leopard has a normal background colour, but its excessive markings have coalesced so that its back seems
to be an unbroken expanse of black. In some specimens, the area of solid black extends down the flanks and limbs; only a few
lateral streaks of golden-brown indicate the presence of normal background colour. Any spots on the flanks and limbs that have
not merged into the mass of swirls and stripes are unusually small and discrete, rather than forming rosettes. The face and
underparts are paler and dappled like those of ordinary spotted leopards.
Black panther: a melanistic leopard
In a paper about panthers and ounces of Asia, Reginald Innes Pocock used a
photo of a leopard skin from southern India; it had large black-rimmed blotches, each containing a number of dots and it
resembled the pattern of a jaguar or clouded leopard. Another of Pocock's leopard skins from southern India had the normal
rosettes broken up and fused and so much additional pigment that the animal looked like a black leopard streaked and speckled
with yellow.
Most other colour morphs of leopards are known only from paintings or museum specimens. There have been very rare examples
where the spots of a normal black leopard have coalesced to give a jet black leopard with no visible markings. Pseudo-melanism
(abundism) occurs in leopards. The spots are more densely packed than normal and merge to largely obscure the background colour.
They may form swirls and, in some places, solid black areas. Unlike a true black leopard the tawny background colour is visible
in places. One pseudo-melanistic leopard had a tawny orange coat with coalescing rosettes and spots, but white belly with normal
black spots (like a black-and-tan dog).
A 1910 description of a pseudo-melanistic leopard:
There is, however, a peculiar dark phase in South Africa, a specimen of which was obtained in 1885 in hilly land covered with
scrub-jungle, near Grahamstown. The ground-colour of this animal was a rich tawny, with an orange tinge; but the spots, instead
of being of the usual rosette-like form, were nearly all small and solid, like those on the head of an ordinary leopard; while
from the top of the head to near the root of the tail the spots became almost confluent, producing the appearance of a broad
streak of black running down the back. A second skin had the black area embracing nearly the whole of the back and flanks,
without showing any trace of the spots, while in those portions of the skin where the latter remained they were of the same form
as in the first specimen. Two other specimens are known; the whole four having been obtained from the Albany district. These
dark-coloured South African leopards differ from the black leopards of the northern and eastern parts of Africa and Asia in that
while in the latter the rosette-like spots are always retained and clearly visible, in the former the rosettes are lost – as,
indeed, is to a considerable extent often the case in ordinary African leopards – and all trace of spots disappears from the
blacker portions of the skin.
—Lydekker, R. (1910), Harmsworth Natural History
Another pseudo-melanistic leopard skin was described in 1915 by Holdridge Ozro Collins who had purchased it in 1912. It had
been killed in Malabar, India that same year.
The wide black portion, which glistens like the sheen of silk velvet, extends from the top of the head to the extremity of the
tail entirely free from any white or tawny hairs … In the tiger, the stripes are black, of a uniform character, upon a tawny
background, and they run in parallel lines from the centre of the back to the belly. In this skin, the stripes are almost golden
yellow, without the uniformity and parallelism of the tiger characteristics, and they extend along the sides in labyrinthine
graceful curls and circles, several inches below the wide shimmering black continuous course of the back. The extreme edges
around the legs and belly are white and spotted like the skin of a leopard … The skin is larger than that of a leopard but
smaller than that of a full grown tiger.
—Collins, Holdridge Ozro(1915)
In May 1936, the British Natural History Museum exhibited the mounted skin of
an unusual Somali leopard. The pelt was richly decorated with an intricate pattern of swirling stripes, blotches, curls and
fine-line traceries. This is different from a spotted leopard, but similar to a King Cheetah
hence the modern cryptozoology term King Leopard. Between 1885 and 1934, six
pseudo-melanistic leopards were recorded in the Albany and Grahamstown districts of South Africa. This indicated a mutation in
the local leopard population. Other King Leopards have been recorded from Malabar in southwestern India. Shooting for trophies
may have wiped out these populations.
Leopards and humans
Leopards have been known to humans since antiquity and have featured in the art, mythology and folklore of many countries
where they have occurred historically, such as Ancient Greece, Persia and Rome, as well as some where they haven't such as England. The modern
use of the leopard as an emblem for sport or coat of arms is much more restricted to Africa, though numerous products worldwide
have used the name.
In captivity
Leopards were kept in a menagerie established by King John at the Tower of London in the 13th century; around 1235 three animals were given to Henry III by the Holy Roman Emperor Frederick
II.[20]
Tourism
Despite its size, this largely nocturnal and arboreal
predator is difficult to see in the wild.

The best location to see leopards in Africa is in the Sabi Sand Private Game Reserve in South
Africa, where leopards are habituated to safari vehicles and are seen on a daily basis at
very close range. In Asia, one can see leopards Yala National Park in
Sri Lanka, which has the world's highest density of wild leopards, but even here sightings are
by no means guaranteed because more than half the park is closed off to the public, allowing the animals to thrive. Another good
destination for leopard watching is the recently reopened Wilpattu National Park, also in Sri
Lanka. In India the leopards are found all over the country and there is maximum man-animal
conflict here only as they are spread everywhere.The best places in India can be national parks in Madhya Pradesh and in Uttarakhand.
Heraldry
Coat of arms of the German state of Baden-Württemberg
-
The lion passant guardant or "leopard" is a frequently used charge in
heraldry, most commonly appearing in groups of three. The heraldric leopard lacks spots and
sports a mane, making it visually almost identical to the heraldric lion, and the two
are often used interchangeably. These traditional lion passant guardants appear in the coat of arms of England and many of its former colonies; more modern naturalistic (leopard-like)
depictions appear on the coat of arms of several African nations including Benin,
Malawi, Somalia,
Democratic Republic of the Congo and
Gabon which uses a black panther. The Leopard is also the unofficial national
animal of Germany, replacing the Tiger, which was, along with the eagle, the national animal of Nazi Germany; the leopard tank was a World War II German tank.
The Leopard Men
The Leopard men were a West African secret society who practised cannibalism. They were centred in Sierra Leone, Liberia and Côte d'Ivoire.
Members would dress in leopard skins, waylaying travellers with sharp claw-like weapons in the form of leopards' claws and
teeth. The victims' flesh would be cut from their bodies and distributed to members of the society. There was a superstitious belief that this ritual cannibalism would strengthen both members of the society as well as
their entire tribe.
Modern culture
Possibly the most famous cinematic leopard is the pet in the film Bringing Up Baby
(1938) where its misadventures create madcap comedy for stars Cary Grant and Katharine Hepburn; the movie is one of the American Film
Institute's "100 Greatest (American) Films".
- In the 1999 Tarzan movie by Disney, a vicious leopard, Sabor, was Tarzan's natural and mortal enemy, although the Mangani name for leopards
established in the books is "Sheeta".
Traditionally, the leopard is an uncommon name or mascot for sporting teams, though it has
been used in several African soccer teams: the AFC
Leopards, formed in 1964, are a soccer club based in Nairobi, Kenya, while the Black Leopards play in South Africa's Premier Soccer League, the Royal Leopards in Swaziland's Premier
League, and the Golf Leopards in the Sierra Leone National Premier League. More recently, the leopard emblem has been a
part of the English Basketball League since the 1990s with the
Essex Leopards and later London Leopards. The
New Zealand Rugby League has featured the Otahuhu Leopards and then the Tamaki Leopards.
The use of Leopards by companies is uncommon, though Nissan Leopard was a luxury
sports car produced by Nissan in the 1980s
and Apple Inc. will release Mac OS X version 10.5,
nicknamed "Leopard" in October.
