Black panther Melanistic leopards are also called black panthers. Pseudomelanism abundism also occurs in leopards. Of the photographs of melanistic leopards, came from study sites south of the Kra Isthmuswhere the non-melanistic morph was never photographed.
Close examination of the color of these black cats will show that the typical markings are still present, but are hidden by the excess black pigment melaningiving an effect similar to that of printed silk.
This is called "ghost striping". Melanistic and non-melanistic animals can be littermates. It is thought that melanism may confer a selective advantage under certain conditions since it is more common in regions of dense forest, where light levels are lower.
Black leopards are common in the equatorial rainforest of the Malay Peninsula and the tropical rainforest on the slopes of some African mountains such as Mount Kenya.
Unconfirmed reports of black leopards exist also in South Africa and in northern Iran. Based on records from camera-traps, melanistic leopards occur foremost in tropical and subtropical moist forestsbut have not been recorded in open and arid habitats. Therefore, coordinated breeding programs for black leopards do not exist in European and North American zoos.
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.
Consequently, black jaguars may produce either black or spotted cubs, but a pair of spotted jaguars can only produce spotted cubs.
Individuals with two copies of the allele are darker the black background colour is more dense than ones with just one copy, whose background colour may appear to be dark charcoal rather than black.
The black jaguar was considered a separate species by indigenous peoples. The jaguar is a beautiful creature, the ground-colour of the fur a rich golden-red tan, abundantly marked with black rings, enclosing one or two small spots within.
This is the typical colouring and it varies little in the temperate regions; in the hot region the Indians recognise three strongly marked varieties, which they regard as distinct species — the one described; the smaller jaguar, less aquatic in his habits and marked with spots, not rings; and, thirdly, the black variety.
They scout the notion that their terrible "black tiger" is a mere melanic variation, like the black leopard of the Old World and the wild black rabbit. They regard it as wholly distinct, and affirm that it is larger and much more dangerous than the spotted jaguar; that they recognise it by its cry; that it belongs to the terra firma rather than to the water-side; finally, that black pairs with black, and that the cubs are invariably black.
Nevertheless, naturalists have been obliged to make it specifically one with Felis onca [Panthera onca], the familiar spotted jaguar, since, when stripped of its hide, it is found to be anatomically as much like that beast as the black is like the spotted leopard.
Melanistic cougars have never been photographed or killed in the wild, and none have ever been bred. Unconfirmed sightings, known as the "North American black panther", are currently attributed to errors in species identification by non-experts, and by the mimetic exaggeration of size.
Black panthers in the American Southeast feature prominently in Choctaw folklore where, along with the owlthey are often thought to symbolize Death. He adds, that there is a third species in these countries, called the black tiger, of which we have given a figure under the appellation of the black cougar.
The head is pretty similar to that of the common cougar; but the animal has long black hair, and likewise a long tail, with strong whiskers. He weighs not much above forty pounds [18 kg]. The female brings forth her young in the hollows of old trees. Another description of a black cougar  was provided by Thomas Pennant: Black tiger, or cat, with the head black, sides, fore part of the legs, and the tail, covered with short and very glossy hairs, of a dusky colour, sometimes spotted with black, but generally plain: At the corner of the mouth a black spot: Long hairs above each eye, and long whiskers on the upper lip: Lower lip, throat, belly and the inside of the legs, whitish, or very pale ash-colour: Grows to the size of a heifer of a year old: Has vast strength in its limbs.
Is a cruel and fierce beast; much dreaded by the Indians; but happily is a scarce species. According to his translator Smelliethe description was taken from two black jaguars exhibited in London some years previously. The Australian "phantom panthers" are said to be responsible for the disappearances and deaths of numerous cats, dogs and livestock.
Animal X Natural Mysteries Unit led an investigation into the phantom panther.
Mike Williams, a local researcher, said he had sent feces and hair found by locals to labs for analysis, which identified it as feces from dogs that had feasted on swamp wallabyand hair from a domestic cat.
Mr Williams said he also had known leopard feces and hair collected from a private zoo tested by one of the same labs, but that these samples came back with the same results of dog feces and domestic cat hair.
This indicated the lab incapable of distinguishing between leopard hairs and those of domestic animals, casting doubt on the previous findings. The lab used was not identified in the episode. The NFL football team the Carolina Panthers is named after the black panther, with a logo resembling the animal.Panther is known as black jaguar in Latin America, as black leopard in Asia and Africa, and as black cougar in North America.
Adult animal has feet in length and weighs between pounds. They are carnivores (meat-eaters). A black form, in which the ground colour as well as the spots is black, is widely known as the black panther; it is more common in Asia than in other parts of the range of the leopard.
The races known as the Barbary, South Arabian, Anatolian, Amur, and Sinai leopards are . A black panther is the melanistic color variant of any big cat species. Black panthers in Asia and Africa are leopards (Panthera pardus), and those in the Americas are black jaguars (Panthera onca).
Black Panther Description Black panthers are members of the big cat family. Their physical appearance has some similarities to that of other big cats, but, since black panthers inhabit vast geographic areas in all kinds of climates and conditions, their physical appearance varies widely.
Other vernacular names for the leopard include graupanther, panther and several regional names such as tendwa in India. The term "black panther" refers to leopards with melanistic genes.  A term for the leopard used in Old English and later, but now very uncommon, is "pard".
A black jaguar (Panthera onca) crouches in a pool of water in Brazil. Black jaguars are also called black panthers, which is an umbrella term for any big cat with a black coat.
