The Leopard (Panthera pardus) is one of the four 'big cats' of the genus Panthera. 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.

[edit] Description
The leopard is the fourth largest of the Panthera "big cats" in the world, behind the tiger, lion and jaguar. The leopard is the fifth largest of all cats with the cougar being slightly larger. Leopards range in size from one to just over two metres (6.5 ft) long, and generally weigh between 30 and 70 kg (65–155 lb). Some Although it is not unusual for a leopard to be mistaken for a cheetah due to their frequently overlapping ranges, they can actually be easily distinguished. The leopard is heavier, stockier, has a larger head in proportion to its body, and has rosettes rather than spots. It also lacks the ring pattern that marks the end of the cheetah's tail and the black, "tear-drop" markings that run from the inner corners of the cheetah's eyes to the corners of its mouth. Additionally, cheetahs run much faster than leopards do and do not climb trees, except while they are cubs, whereas leopards are excellent climbers. Also, leopards are more active at night (nocturnal), whereas cheetahs are usually diurnal.
[edit] Unrelated species called "leopards"
Some cats are called leopards, but they belong to other species:
- Clouded Leopard, Neofelis nebulosa
- Bornean Clouded Leopard, Neofelis diardi
- Snow Leopard, Uncia uncia
[edit] Black panthers
A black panther is a melanistic leopard (or melanistic jaguar). These have mutations that cause them to produce more black pigment (eumelanin) than orange-tan pigment (pheomelanin). This results in a chiefly black coat, though the spots of a black panther can still be discerned in certain light as the deposition of pigment is different in the pattern than in the background. There are also white panthers.
[edit] Distribution and conservation
Prior to the human-induced changes of the last few hundred years, Leopards were the most widely distributed of all felids other than the domestic cat: they were found in historical times through most of Africa (with the exception of the Sahara Desert) and in many parts of southern Asia. In the Pleistocene leopards also occurred in Europe. Today leopards are still found in many parts of Sub-Saharan Africa, Asia Minor, the Middle East, India, Pakistan, China, Siberia, much of mainland South-East Asia, and the islands of Java and Sri Lanka. In some of these areas they are very rare today.
The leopard is doing surprisingly well for a large predator. It is estimated that there are as many as 50,000 leopards worldwide. But like many other big cats, leopards are increasingly under threat of habitat loss and are facing increased hunting pressure. Because of their stealthy habits and camouflage, they can go undetected even in close proximity to human settlements. Despite the leopard's abilities, it is no match for habitat destruction and poachers, and several subspecies are endangered, namely, the Amur, Anatolian, Barbary, North Chinese, and South Arabian leopards.
[edit] Behaviour and predation
Leopards are infamous for their ability to go undetected. They sometimes live practically among humans and are usually still tough to spot. They are graceful and stealthy. Amongst the big cats they are probably the most accomplished stalkers. They are good, agile climbers and can descend from a tree headfirst. 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 behavior is more common. These cats are solitary, avoiding one another. However, 3 or 4 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.
Leopards have difficulty defending kills from large social predators, such as lion or hyena. In areas with large numbers of large predators, they typically store their kills out of reach in trees. Although a leopard caught on the ground will typically try to defend its kill, it will generally find itself outmatched by these predators. If outnumbered, it will abandon its kill and seek safety in trees.
Leopards are truly opportunistic hunters. They will eat just about any animal. Their diet consists of mostly monkeys, rodents, reptiles, amphibians, birds, fish, wild pigs, and ungulates. In fact, they hunt about 90 different species of animals. Their prey ranges in size from a snack of beetles to Antelopes. In Africa, mid-sized antelopes provide a majority of the leopard's prey, especially Thomson's gazelles and reedbucks. It stalks its prey silently and at the last minute pounces on its prey and strangles its throat with a quick bite. When it kills animals such as gazelle, it carries them up into the trees to eat it. Leopards are capable of carrying animals up to twice their own weight into the trees.
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.
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, the best site is the 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. The recently reopened Wilpattu National Park (also in Sri Lanka), is another good destination for leopard watching.
[edit] Reproduction
Males 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. 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 3 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.
[edit] Taxonomy
[edit] Subspecies
It has been suggested that there may be as many as 30 extant subspecies of the Leopard; however, most of these are questionable. However modern taxonomics analises have been demostrate that only 8/9 subspecies are valids [1]:
- Panthera pardus pardus (Africa)
- Panthera pardus saxicolor (Central Asia)
- Panthera pardus fusca (India)
- Panthera pardus kotiya (Sri Lanka)
- Panthera pardus delacouri (Indochina)
- Panthera pardus japonensis (China)
- Panthera pardus orientalis or Amurensis (Amur Region, border Russia, China, North Korea)
- Panthera pardus melas (Java)
- Panthera pardus nimr (Arabia) (Uncertain subspecies)
Under the old taxonomic division:
- African Leopard, Panthera pardus pardus (lower risk, least concern)
- Amur leopard, Panthera pardus orientalis (critically endangered)
- Anatolian Leopard, Panthera pardus tulliana (critically endangered, possibly extinct)
- Arabian Leopard, Panthera pardus nimr (critically endangered)
- Barbary Leopard, Panthera pardus panthera (critically endangered, possibly extinct)
- Caucasus Leopard Panthera pardus ciscaucasica (endangered)
- Indian Leopard*, Panthera pardus fusca (lower risk)
- Indo-Chinese Leopard*, Panthera pardus delacouri (vulnerable)
- Java Leopard*, Panthera pardus melas (endangered)
- North China Leopard*, Panthera pardus japonensis (vulnerable)
- Persian Leopard or Iranian leopard*, Panthera pardus saxicolor (endangered)
- Sinai Leopard, Panthera pardus jarvisi (critically endangered, possibly extinct)

[edit] King Leopard
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.
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.
[edit] Heraldry
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 interchangably. These traditional lion passant guardants appear in the coat of arms of England and many of its former colonies; more modern naturalistic depictions appear in the coat of arms of Benin and other countries, and are more recognizably leopard-like.
[edit] In media
- The zany movie Bringing Up Baby (1939) gives title billing to a leopard whose 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".
- In Passion in the Desert (1997), a French soldier (played by British actor Ben Daniels) while lost in Egypt during Napoleon's Egyptian campaign stumbles upon a leopard and develops a strange relationship with the animal[2].
