The jaguar (Panthera onca) is a large felid species and the only extant member of the genus Panthera native to the Americas. The jaguar's present range extends from the southwestern United States and Mexico in North America, across much of Central America, and south to Paraguay and northern Argentina in South America. Though there are single cats now living within Arizona, the species has largely been extirpated from the United States since the early 20th century. It is listed as Near Threatened on the IUCN Red List; and its numbers are declining. Threats include loss and fragmentation of habitat.

Contents

Overall, the jaguar is the largest native cat species of the New World and the third largest in the world. This spotted cat closely resembles the leopard, but is usually larger and sturdier. It ranges across a variety of forested and open terrains, but its preferred habitat is tropical and subtropical moist broadleaf forest, swamps and wooded regions. The jaguar enjoys swimming and is largely a solitary, opportunistic, stalk-and-ambush predator at the top of the food chain. As a keystone species it plays an important role in stabilizing ecosystems and regulating prey populations.

While international trade in jaguars or their body parts is prohibited, the cat is still frequently killed, particularly in conflicts with ranchers and farmers in South America. Although reduced, its range remains large. Given its historical distribution, the jaguar has featured prominently in the mythology of numerous indigenous peoples of the Americas, including those of the Maya and Aztec civilizations.

Etymology

The word 'jaguar' is derived from 'iaguara', a word in one of the indigenous languages of Brazil for a wild spotted cat that is larger than a wolf. [2] Onca is derived from the Lusitanian name 'onça' for a spotted cat in Brazil that is larger than a lynx. [3] Indigenous peoples in Guyana call it 'jaguareté'. [4]

The word 'panther' derives from classical Latin panthēra, itself from the ancient Greek pánthēr (πάνθηρ). [5]

Taxonomy

In 1758, Carl Linnaeus described the jaguar in his work Systema Naturae and gave it the scientific name Felis onca. [6] In the 19th and 20th centuries, several jaguar type specimens formed the basis for descriptions of subspecies. [7] In 1939, Reginald Innes Pocock recognized eight subspecies based on geographic origins and skull morphology of these specimens. [8] Pocock did not have access to sufficient zoological specimens to critically evaluate their subspecific status, but expressed doubt about the status of several. Later consideration of his work suggested only three subspecies should be recognized. The description of P. o. palustris was based on a fossil skull. [9] By 2005, nine subspecies were considered to be valid taxa. [7]

Reginald Innes Pocock placed the jaguar in the genus Panthera and observed that it shares several morphological features with the leopard (P. pardus). He therefore concluded that they are most closely related to each other. [8] Results of morphologic and genetic research indicate a clinal north–south variation between populations, but no evidence for subspecific differentiation. [17] [18] A subsequent, more detailed study confirmed the predicted population structure within jaguar populations in Colombia. [19]

Since 2017, the jaguar is therefore considered to be a monotypic taxon. [20]

Evolution

The genus Panthera probably evolved in Asia between 6 to 10 million years ago . [21] Phylogenetic studies generally have shown the clouded leopard (Neofelis nebulosa) is basal to this group. [22] [23] [24]

The jaguar is thought to have genetically diverged from a common ancestor of the Panthera at least 1.5  million years ago and to have entered the American continent in the Early Pleistocene via Beringia, the land bridge that once spanned the Bering Strait. Results of jaguar mitochondrial DNA analysis indicate that the species' lineage evolved between 280,000 and 510,000 years ago. [17] Fossils of the extinct Panthera gombaszoegensis and the American lion (P. atrox) show characteristics of both the jaguar and the lion (P. leo). [22] Results of DNA-based studies are conclusive, and the position of the jaguar relative to the other species varies depending on methods and sample sizes used. [21] [22] [23] [24]

Its immediate ancestor was Panthera onca augusta , which was larger than the contemporary jaguar. [19] Jaguar fossils were discovered in Whitman County, Washington, Fossil Lake (Oregon), Niobrara, Nebraska, Franklin County, Tennessee, Edwards County, Texas, and in eastern Florida. A skeleton and pug marks of a jaguar were found in the Craighead Caverns. These fossils are dated to the Pleistocene between 40,000 and 11,500 years ago. [25]

The jaguar is a compact and well-muscled animal. It is the largest cat native to the Americas and the third largest in the world, exceeded in size by the tiger and the lion. [9] [26] [27] Its coat is generally a tawny yellow, but ranges to reddish-brown, for most of the body. The ventral areas are white. [15] The fur is covered with rosettes for camouflage in the dappled light of its forest habitat. The spots and their shapes vary between individual jaguars: rosettes may include one or several dots. The spots on the head and neck are generally solid, as are those on the tail, where they may merge to form a band. [9] Jaguars living in forests are often darker and considerably smaller than those living in open areas, possibly due to the smaller numbers of large, herbivorous prey in forest areas. [28]

Its size and weight vary considerably: weights are normally in the range of 56–96 kg (123–212 lb). Exceptionally big males have been recorded to weigh as much as 158 kg (348 lb). [29] [30] The smallest females weigh about 36 kg (79 lb). [29] It is sexually dimorphic with females typically 10–20% smaller than males. The length, from the nose to the base of the tail, varies from 1.12 to 1.85 m (3 ft 8 in to 6 ft 1 in). The tail is the shortest of any big cat, at 45 to 75 cm (18 to 30 in) in length. [29] [31] Legs are also short, but thick and powerful, considerably shorter when compared to a small tiger or lion in a similar weight range. The jaguar stands 63 to 76 cm (25 to 30 in) tall at the shoulders. [32]

Further variations in size have been observed across regions and habitats, with size tending to increase from north to south. Jaguars in the Chamela-Cuixmala Biosphere Reserve on the Pacific coast weighed around 50 kg (110 lb), about the size of a female cougar. [33] Jaguars in Venezuela and Brazil are much larger with average weights of about 95 kg (209 lb) in males and of about 56–78 kg (123–172 lb) in females. [9]

A short and stocky limb structure makes the jaguar adept at climbing, crawling, and swimming. [32] The head is robust and the jaw extremely powerful, it has the third highest bite force of all felids, after the tiger and the lion. [34] A 100 kg (220 lb) jaguar can bite with a force of 4.939 kilonewtons (1,110 pounds-force) with the canine teeth and 6.922 kN (1,556 lbf) at the carnassial notch. [35] It was ranked as the top felid in a comparative study of bite force adjusted for body size, alongside the clouded leopard and ahead of the tiger and lion. [36]

While the jaguar closely resembles the leopard, it is generally more robust, with stockier limbs and a squarer head. The rosettes on a jaguar's coat are larger, darker, fewer in number and have thicker lines with a small spot in the middle. [37]

Color variation

Melanistic jaguars are informally known as black panthers. The black morph is less common than the spotted one. [38] Melanism in the jaguar is caused by deletions in the melanocortin 1 receptor gene and inherited through a dominant allele. [39]

In Mexico's Sierra Madre Occidental, the first black jaguar was recorded in 2004. [40] Black jaguars were also recorded in Costa Rica's Alberto Manuel Brenes Biological Reserve and in the mountains of the Cordillera de Talamanca. [41] [42]

Albino jaguars, sometimes called white panthers, are extremely rare. [28]

At present, the jaguar's range extends from Mexico through Central America to South America, including much of Amazonian Brazil. The countries included in this range are Argentina, Belize, Bolivia, Colombia, Costa Rica (particularly on the Osa Peninsula), Ecuador, French Guiana, Guatemala, Guyana, Honduras, Nicaragua, Panama, Paraguay, Peru, Suriname, the United States and Venezuela. It is now locally extinct in El Salvador and Uruguay. [1]

The jaguar prefers dense forest and typically inhabits dry deciduous forests, tropical and subtropical moist broadleaf forests, rainforests and cloud forests in Central and South America; open, seasonally flooded wetlands, dry grassland and historically also oak forests in the United States. It has been recorded at elevations up to 3,800 m (12,500 ft), but avoids montane forests. It favours riverine habitat and swamps with dense vegetation cover. [28] It has lost habitat most rapidly in drier regions such as the Argentine pampas, the arid grasslands of Mexico and the southwestern United States. [1]

In 1919, the jaguar was said to have occurred in the Monterey, California region. [43] In 1999, its historic range at the turn of the 20th century was estimated at 19,000,000 km2 (7,300,000 sq mi) stretching from the southern United States through Central America to southern Argentina. By the turn of the 21st century, its global range had decreased to about 8,750,000 km2 (3,380,000 sq mi), most of it in the southern United States, northern Mexico, northern Brazil, and southern Argentina. [44] Occasional sightings were reported in Arizona, [45] New Mexico and Texas. [46]

Ecology and behavior

Ecological role

The adult jaguar is an apex predator, meaning it is at the top of the food chain and is not preyed upon in the wild. The jaguar has also been termed a keystone species, as it is assumed that it controls the population levels of prey such as herbivorous and granivorous mammals, and thus maintains the structural integrity of forest systems. [33] [47] [48]

However, accurately determining what effect species like the jaguar have on ecosystems is difficult, because data must be compared from regions where the species is absent as well as its current habitats, while controlling for the effects of human activity. It is accepted that mid-sized prey species undergo population increases in the absence of the keystone predators, and this has been hypothesized to have cascading negative effects. [49] However, field work has shown this may be natural variability and the population increases may not be sustained. Thus, the keystone predator hypothesis is not accepted by all scientists. [50]

The jaguar also has an effect on other predators. The jaguar and the cougar, which is the next-largest feline of South America, but the biggest in Central or North America, [33] are often sympatric (related species sharing overlapping territory) and have often been studied in conjunction. The jaguar tends to take larger prey, usually over 22 kg (49 lb) and the cougar smaller, usually between 2 and 22 kg (4 and 49 lb), reducing the latter's size. [51] This situation may be advantageous to the cougar. Its broader prey niche, including its ability to take smaller prey, may give it an advantage over the jaguar in human-altered landscapes; [33] while both are classified as near-threatened species, the cougar has a significantly larger current distribution. Depending on the availability of prey, the cougar and jaguar may even share it. [52]

Hunting and diet

Like all cats, the jaguar is an obligate carnivore, feeding only on meat. It is an opportunistic hunter, and its diet encompasses at least 87 species. [28] It prefers prey weighing 45–85 kg (99–187 lb), with capybara (Hydrochoerus hydrochaeris) and giant anteater (Myrmecophaga tridactyla) being the most preferred species. Other commonly taken prey include wild boar (Sus scrofa), Odocoileus deer, collared peccary (Pecari tajacu), spectacled caiman (Caiman crocodilus) in the northern parts of its range, nine-banded armadillo (Dasypus novemcinctus), white-nosed coati (Nasua narica), frogs, and fish. [26] Jaguars are unusual among large felids in that they do not have a special preference for even-toed ungulates. [26] Some jaguars also prey on livestock such as horses, cattle, and llamas. [53] In the Arizona mountains, a jaguar killed and fed on an American black bear (Ursus americanus). [54]

Its bite force allows it to pierce the shells of armored reptiles and turtles. [55] It bites into the throat of South American tapir (Tapirus terrestris) and other large prey until the victim suffocates. It kills capybara by piercing its canine teeth through the temporal bones of the capybara's skull, breaking its zygomatic arch and mandible and penetrating its brain, often through the ears. [56] This may be an adaptation to "cracking open" turtle shells; armored reptiles may have formed an abundant prey base for the jaguar following the late Pleistocene extinctions. [55] It has been reported that an individual jaguar can drag an 360 kg (800 lb) bull 8 m (25 ft) in its jaws and pulverize the heaviest bones. [57]

The activity patterns of the jaguar have been found to coincide with the activity of their main prey species in their biomes. [58] Camera trap studies have shown that jaguars primarily have a crepuscularnocturnal activity pattern in all the biomes that they are found in; however jaguars have been recorded to have considerable diurnal activity in thickly forested regions of the Amazon Rainforest and the Pantanal, as well as purely nocturnal activity in other regions such as the Atlantic forest. [59]

The jaguar is a stalk-and-ambush rather than a chase predator. The cat will walk slowly down forest paths, listening for and stalking prey before rushing or ambushing. The jaguar attacks from cover and usually from a target's blind spot with a quick pounce; the species' ambushing abilities are considered nearly peerless in the animal kingdom by both indigenous people and field researchers, and are probably a product of its role as an apex predator in several different environments. [60] The ambush may include leaping into water after prey, as a jaguar is quite capable of carrying a large kill while swimming; its strength is such that carcasses as large as a heifer can be hauled up a tree to avoid flood levels. After killing prey, the jaguar will drag the carcass to a thicket or other secluded spot. It begins eating at the neck and chest, rather than the midsection. The heart and lungs are consumed, followed by the shoulders. [60]

The daily food requirement of a 34 kg (75 lb) animal, at the extreme low end of the species' weight range, has been estimated at 1.4 kg (3 lb). [61] For captive animals in the 50–60 kg (110–130 lb) range, more than 2 kg (4 lb) of meat daily are recommended. [62] In the wild, consumption is naturally more erratic; wild cats expend considerable energy in the capture and kill of prey, and they may consume up to 25 kg (55 lb) of meat at one feeding, followed by periods of famine. [63] Though carnivorous, there is evidence that wild jaguars consume the roots of Banisteriopsis caapi . [64]

Reproduction and life cycle

Jaguar females reach sexual maturity at about two years of age, and males at three or four. The cat probably mates throughout the year in the wild, with births increasing when prey is plentiful. [65] Research on captive male jaguars supports the year-round mating hypothesis, with no seasonal variation in semen traits and ejaculatory quality; low reproductive success has also been observed in captivity. [66] Generation length of the jaguar is 9.8 years. [67]

Female estrus is 6–17 days out of a full 37-day cycle, and females will advertise fertility with urinary scent marks and increased vocalization. [65] Females range more widely than usual during courtship. Pairs separate after mating, and females provide all parenting. The gestation period lasts 93–105 days; females give birth to up to four cubs, and most commonly to two. The mother will not tolerate the presence of males after the birth of cubs, given a risk of infanticide; this behavior is also found in the tiger. [60]

The young are born blind, gaining sight after two weeks. Cubs are weaned at three months, but remain in the birth den for six months before leaving to accompany their mother on hunts. [68] They will continue in their mother's company for one to two years before leaving to establish a territory for themselves. Young males are at first nomadic, jostling with their older counterparts until they succeed in claiming a territory. Typical lifespan in the wild is estimated at around 12–15 years; in captivity, the jaguar lives up to 23 years, placing it among the longest-lived cats. [69]

Social activity

Like most cats, the jaguar is solitary outside mother–cub groups. Adults generally meet only to court and mate (though limited noncourting socialization has been observed anecdotally [60] ) and carve out large territories for themselves. Female territories, which range from 25 to 40 km2 in size, may overlap, but the animals generally avoid one another. Male ranges cover roughly twice as much area, varying in size with the availability of game and space, and do not overlap. The territory of a male can contain those of several females. [60] [70] The jaguar uses scrape marks, urine, and feces to mark its territory. [71] [72]

Like the other big cats except the snow leopard, the jaguar is capable of roaring [73] [74] and does so to warn territorial and mating competitors away; intensive bouts of counter-calling between individuals have been observed in the wild. [55] Their roar often resembles a repetitive cough, and they may also vocalize mews and grunts. [69] Mating fights between males occur, but are rare, and aggression avoidance behavior has been observed in the wild. [71] When it occurs, conflict is typically over territory: a male's range may encompass that of two or three females, and he will not tolerate intrusions by other adult males. [60]

The jaguar is often described as nocturnal, but is more specifically crepuscular (peak activity around dawn and dusk). Both sexes hunt, but males travel farther each day than females, befitting their larger territories. The jaguar may hunt during the day if game is available and is a relatively energetic feline, spending as much as 50–60 percent of its time active. [28] The jaguar's elusive nature and the inaccessibility of much of its preferred habitat make it a difficult animal to sight, let alone study.

Attacks on humans

Jaguars did not evolve eating large primates and do not normally see man as food. [75] Experts have cited them as the least likely of all big cats to kill and eat man and the majority of attacks come when it has been cornered or wounded. [76] However, such behavior appears to be more frequent where humans enter jaguar habitat and decrease prey. [77] Captive jaguars sometimes attack zookeepers. [78] When the conquistadors arrived in the Americas, they feared jaguars. Nevertheless, even in those times, the jaguar's chief prey was the capybara in South America and peccary further north. Charles Darwin reported a saying of Indigenous peoples of the Americas that people would not have to fear the jaguar as long as capybaras were abundant. [79]

Jaguar populations are rapidly declining. The species is listed as Near Threatened on the IUCN Red List. The loss of parts of its range, including its virtual elimination from its historic northern areas and the increasing fragmentation of the remaining range, have contributed to this status. [1] Particularly significant declines occurred in the 1960s, when more than 15,000 jaguars were killed for their skins in the Brazilian Amazon yearly; the Convention on International Trade in Endangered Species of 1973 brought about a sharp decline in the pelt trade. [80] Detailed work performed under the auspices of the Wildlife Conservation Society revealed the species has lost 37% of its historic range, with its status unknown in an additional 18% of the global range. More encouragingly, the probability of long-term survival was considered high in 70% of its remaining range, particularly in the Amazon basin and the adjoining Gran Chaco and Pantanal. [44]

The major risks to the jaguar include deforestation across its habitat, increasing competition for food with human beings, especially in dry and unproductive habitat, [1] [81] poaching, hurricanes in northern parts of its range, and the behavior of ranchers who will often kill the cat where it preys on livestock. When adapted to the prey, the jaguar has been shown to take cattle as a large portion of its diet; while land clearance for grazing is a problem for the species, the jaguar population may have increased when cattle were first introduced to South America, as the animals took advantage of the new prey base. This willingness to take livestock has induced ranch owners to hire full-time jaguar hunters. [69]

The skins of wild cats and other mammals have been highly valued by the fur trade for many decades. From the beginning of the 20th-century Jaguars were hunted in large numbers, but over-harvest and habitat destruction reduced the availability and induced hunters and traders to gradually shift to smaller species by the 1960s. The international trade of jaguar skins had its largest boom between the end of the Second World War and the early 1970, due to the growing economy and lack of regulations. From 1967 onwards, the regulations introduced by national laws and international agreements diminished the reported international trade from as high as 13000 skins in 1967, through 7000 skins in 1969, until it became negligible after 1976, although illegal trade and smuggling continue to be a problem. During this period, the biggest exporters were Brazil and Paraguay, and the biggest importers were the US and Germany. [82]

Conservation

The jaguar is listed on CITES Appendix I, which means that all international trade in jaguars or their body parts is prohibited. Hunting jaguars is prohibited in Argentina, Brazil, Colombia, French Guiana, Honduras, Nicaragua, Panama, Paraguay, Suriname, the United States, and Venezuela. Hunting jaguars is restricted in Guatemala and Peru. [1] Trophy hunting is still permitted in Bolivia, and it is not protected in Ecuador or Guyana. [83]

Jaguar Conservation Units

Jaguar conservation is complicated because of the species' large range spanning 18 countries with different policies and regulations. Specific areas of high importance for jaguar conservation, so-called "Jaguar Conservation Units" (JCU) were determined in 2000. These are large areas inhabited by at least 50 jaguars. Each unit was assessed and evaluated on the basis of size, connectivity, habitat quality for both jaguar and prey, and jaguar population status. That way, 51 Jaguar Conservation Units were determined in 36 geographic regions as priority areas for jaguar conservation including: [44]

Recent studies underlined that to maintain the robust exchange across the jaguar gene pool necessary for maintaining the species, it is important that jaguar habitats are interconnected. To facilitate this, a new project, the Paseo del Jaguar, has been established to connect several jaguar hotspots. [84]

In 1986, the Cockscomb Basin Wildlife Sanctuary was established in Belize as the world's first protected area for jaguar conservation. [85]

Given the inaccessibility of much of the species' range, particularly the central Amazon, estimating jaguar numbers is difficult. Researchers typically focus on particular bioregions, thus species-wide analysis is scant. In 1991, 600–1,000 (the highest total) were estimated to be living in Belize. A year earlier, 125–180 jaguars were estimated to be living in Mexico's 4,000-km2 (2400-mi2) Calakmul Biosphere Reserve, with another 350 in the state of Chiapas. The adjoining Maya Biosphere Reserve in Guatemala, with an area measuring 15,000 km2 (9,000 mi2), may have 465–550 animals. [86] Work employing GPS telemetry in 2003 and 2004 found densities of only six to seven jaguars per 100 km2 in the critical Pantanal region, compared with 10 to 11 using traditional methods; this suggests the widely used sampling methods may inflate the actual numbers of cats. [87]

Approaches

In setting up protected reserves, efforts generally also have to be focused on the surrounding areas, as jaguars are unlikely to confine themselves to the bounds of a reservation, especially if the population is increasing in size. Human attitudes in the areas surrounding reserves and laws and regulations to prevent poaching are essential to make conservation areas effective. [88]

To estimate population sizes within specific areas and to keep track of individual jaguars, camera trapping and wildlife tracking telemetry are widely used, and feces may be sought out with the help of detector dogs to study jaguar health and diet. [87] [89] Current conservation efforts often focus on educating ranch owners and promoting ecotourism. [90] The jaguar is generally defined as an umbrella species – its home range and habitat requirements are sufficiently broad that, if protected, numerous other species of smaller range will also be protected. [91] Umbrella species serve as "mobile links" at the landscape scale, in the jaguar's case through predation. Conservation organizations may thus focus on providing viable, connected habitat for the jaguar, with the knowledge other species will also benefit. [90]

Ecotourism setups are being used to generate public interest in charismatic animals such as the jaguar, while at the same time generating revenue that can be used in conservation efforts. Audits done in Africa have shown that ecotourism has helped in African cat conservation. As with large African cats, a key concern in jaguar ecotourism is the considerable habitat space the species requires, so if ecotourism is used to aid in jaguar conservation, some considerations need to be made as to how existing ecosystems will be kept intact, or how new ecosystems that are large enough to support a growing jaguar population will be put into place. [92]

The United States

Jaguars are occasionally sighted in Arizona and New Mexico. [93] [94] [95] In August 2012, the USFWS proposed setting aside 3,392.20 km2 (838,232 acres) in Arizona and New Mexico for the protection of the jaguar. [96]

In culture and mythology

A conch shell gorget depicting a jaguar was found in a burial mound in Benton County, Missouri. The gorget shows evenly-engraved lines and measures 104 mm × 98 mm (4.1 in × 3.9 in). [25] Rock drawings made by the Hopi, Anasazi and Pueblo all over the desert and chaparral regions of the American Southwest show an explicitly spotted cat, presumably a jaguar, as it is drawn much larger than an ocelot. [46]

In pre-Columbian Central and South America, the jaguar was a symbol of power and strength. In the Andes, a jaguar cult disseminated by the early Chavín culture became accepted over most of today's Peru by 900 BC. The later Moche culture of northern Peru used the jaguar as a symbol of power in many of their ceramics. [97] [98] [99] In the religion of the Muisca, who inhabited the cool Altiplano Cundiboyacense in the Colombian Andes, the jaguar was considered a sacred animal and during their religious rituals the people dressed in jaguar skins. [100] The skins were traded with the lowland peoples of the tropical Orinoquía Region. [101] The name of zipa Nemequene was derived from the Muysccubun words nymy and quyne, meaning "force of the jaguar". [102] [103]

In Mesoamerica, the Olmec—an early and influential culture of the Gulf Coast of Mexico roughly contemporaneous with the Chavín—developed a distinct "Olmec were-jaguar" motif of sculptures and figurines showing stylised jaguars or humans with jaguar characteristics. In the later Maya civilization, the jaguar was believed to facilitate communication between the living and the dead and to protect the royal household. The Maya saw these powerful felines as their companions in the spiritual world, and a number of Maya rulers bore names that incorporated the Mayan word for jaguar (b'alam in many of the Mayan languages). Balam (Jaguar) remains a common Maya surname, and it is also the name of Chilam Balam, a legendary author to whom are attributed 17th and 18th-centuries Maya miscellanies preserving much important knowledge. The Aztec civilization shared this image of the jaguar as the representative of the ruler and as a warrior. The Aztecs formed an elite warrior class known as the Jaguar warrior. In Aztec mythology, the jaguar was considered to be the totem animal of the powerful deity Tezcatlipoca. [60] [104] Remains of jaguar bones were discovered in a burial site in Guatemala which indicates that Mayans kept jaguars as pets. [105]

Contemporary culture

The jaguar and its name are widely used as a symbol in contemporary culture. It is the national animal of Guyana, and is featured in its Coat of arms of Guyana. [106] The flag of the Department of Amazonas features a black jaguar silhouette pouncing towards a hunter. [107] The jaguar also appears in banknotes of the Brazilian real. The jaguar is also a common fixture in the mythology of several native cultures in South America. [108]

The crest of the Argentine Rugby Union features a jaguar; however, the Argentina national rugby union team is nicknamed Los Pumas. [109] In the spirit of the ancient Mayan culture, the 1968 Summer Olympics in Mexico City adopted a red jaguar as the first official Olympic mascot. [110]

Felidae Family of mammals

Felidae is a family of mammals in the order Carnivora, colloquially referred to as cats, and constitutes a clade. A member of this family is also called a felid. The term "cat" refers both to felids in general and specifically to the domestic cat.

Tiger Largest species of the cat family

The tiger is the largest extant cat species and a member of the genus Panthera. It is most recognisable for its dark vertical stripes on orange-brown fur with a lighter underside. It is an apex predator, primarily preying on ungulates such as deer and wild boar. It is territorial and generally a solitary but social predator, requiring large contiguous areas of habitat, which support its requirements for prey and rearing of its offspring. Tiger cubs stay with their mother for about two years, before they become independent and leave their mother's home range to establish their own.

A black panther is the melanistic colour variant of any Panthera, particularly of the leopard in Asia and Africa, and the jaguar in the Americas. Black panthers of both species have excess black pigments, but their typical spotted markings are also present. Melanism in the leopard is caused by a recessive allele, and in the jaguar by a dominant allele.

Leopard A large cat native to Africa and Eurasia

The leopard is one of the five extant species in the genus Panthera, a member of the Felidae. It occurs in a wide range in sub-Saharan Africa, in small parts of Western and Central Asia, on the Indian subcontinent to Southeast and East Asia. It is listed as Vulnerable on the IUCN Red List because leopard populations are threatened by habitat loss and fragmentation, and are declining in large parts of the global range. In Hong Kong, Singapore, Kuwait, Syria, Libya, Tunisia and most likely in Morocco, leopard populations have already been extirpated. Contemporary records suggest that the leopard occurs in only 25% of its historical global range.

<i>Panthera</i> Genus within Felidae

Panthera is a genus within the family Felidae that was named and described by Lorenz Oken in 1816 who placed all the spotted cats in this group. Reginald Innes Pocock revised the classification of this genus in 1916 as comprising the species tiger, lion, jaguar, and leopard on the basis of common cranial features. Results of genetic analysis indicate that the snow leopard also belongs to the Panthera, a classification that was accepted by IUCN Red List assessors in 2008.

Cougar Large species of the family Felidae native to the Americas

The cougar is a large cat of the subfamily Felinae. It is native to the Americas. Its range spans from the Canadian Yukon to the southern Andes in South America, and is the widest of any large wild terrestrial mammal in the Western Hemisphere. It is an adaptable, generalist species, occurring in most American habitat types. Due to its wide range, it has many names including puma, mountain lion, panther, painter and catamount.

Big cat larger felid species

The term "bigcat" is typically used to refer to any of the five living members of the genus Panthera, namely tiger, lion, jaguar, leopard, and snow leopard. Except the snow leopard, these species are able to roar. A more liberal and expansive definition of the term includes species outside of Panthera including the cougar, clouded leopard, Sunda clouded leopard, cheetah and sometimes the several lynx species, although these added species also do not roar.

<i>Dinofelis</i> extinct genus of mammals

Dinofelis is a genus of extinct sabre-toothed cats belonging to the tribe Metailurini. They were widespread in Europe, Asia, Africa and North America at least 5 million to about 1.2 million years ago. Fossils very similar to Dinofelis from Lothagam range back to the Late Miocene, some 8 million years ago.

Bengal tiger Tiger population in Indian subcontinent

The Bengal tiger is a tiger from a specific population of the Panthera tigris tigris subspecies that is native to the Indian subcontinent. It is threatened by poaching, loss, and fragmentation of habitat, and was estimated at comprising fewer than 2,500 wild individuals by 2011. None of the Tiger Conservation Landscapes within its range is considered large enough to support an effective population of more than 250 adult individuals. India's tiger population was estimated at 1,706–1,909 individuals in 2010. By 2018, the population had increased to an estimated 2,603–3,346 individuals. Around 300–500 tigers are estimated in Bangladesh, 220–274 tigers in Nepal and 103 tigers in Bhutan.

Ocelot Small wild cat

The ocelot is a small wild cat native to the southwestern United States, Mexico, and Central and South America. This medium-sized cat is characterized by solid black spots and streaks on its coat, round ears, and white neck and undersides. It weighs between 8 and 15.5 kg and reaches 40–50 cm at the shoulders. It was first described by Carl Linnaeus in 1758. Two subspecies are recognized: L. p. pardalis and L. p. mitis.

Jaguarundi Small wild cat

The jaguarundi is a wild cat native to the Americas. Its range extends from central Argentina in the south to the US–Mexico border in the north, through Central and South America east of the Andes. The jaguarundi is a medium-sized cat of slender build. Its coloration is uniform, similar to that of its closest relative, the much larger cougar, but differing significantly from other neotropical cats. It has an elongated body with relatively short legs, a small, narrow head, small, round ears, a short snout and a long tail, resembling otters and weasels in these respects. It is around twice as large as the domestic cat, reaching nearly 36 cm (14 in) at the shoulder and weighs 3.5–7 kg (7.7–15.4 lb). It has two color morphs — gray and red.

American lion species of mammal (fossil)

The American lion, also known as the "North American lion", or "American cave lion", is an extinct pantherine cat that lived in North America during the Pleistocene epoch and the early Holocene epoch, about 340,000 to 11,000 years ago. Its fossils have been excavated from Alaska to Mexico. Genetic analysis has shown that the American lion and the Late Pleistocene Eurasian cave lion are sister lineages. It was about 25% larger than the modern lion, making it one of the largest known felids.

Sumatran tiger subspecies of mammal

The Sumatran tiger is a population of Panthera tigris sondaica in the Indonesian island of Sumatra. This population was listed as Critically Endangered on the IUCN Red List in 2008, as it was estimated at 441 to 679 individuals, with no subpopulation larger than 50 individuals and a declining trend.

Malayan tiger Tiger population in Malayan Peninsula

The Malayan tiger is a tiger from a specific population of the Panthera tigris tigris subspecies that is native to Peninsular Malaysia. This population inhabits the southern and central parts of the Malay Peninsula and has been classified as critically endangered on the IUCN Red List in 2015. The population was estimated at 250 to 340 adult individuals in 2013 and likely comprises less than 200 mature breeding individuals and has a declining trend.

African leopard Leopard subspecies

The African leopard is the nominate subspecies of the leopard, native to many countries in Africa. It is widely distributed in most of sub-Saharan Africa, but the historical range has been fragmented in the course of habitat conversion. Leopards have been recorded in North Africa as well.

<i>Panthera gombaszoegensis</i> Extinct European jaguar species

Panthera gombaszoegensis, also known as the European jaguar, is a Panthera species that lived from about 2.0 to 0.35 million years ago in Europe. The first fossils were excavated in 1938 in Gombaszög, Slovakia.

Indian leopard Leopard subspecies

The Indian leopard is a leopard subspecies widely distributed on the Indian subcontinent. The species Panthera pardus is listed as Vulnerable on the IUCN Red List because populations have declined following habitat loss and fragmentation, poaching for the illegal trade of skins and body parts, and persecution due to conflict situations.

Snow leopard species of mammal

The snow leopard, also known as the ounce, is a large cat native to the mountain ranges of Central and South Asia. It is listed as Vulnerable on the IUCN Red List because the global population is estimated to number less than 10,000 mature individuals and is expected to decline about 10% by 2040. It is threatened by poaching and habitat destruction following infrastructural developments. It inhabits alpine and subalpine zones at elevations from 3,000 to 4,500 m, ranging from eastern Afghanistan, the Himalayas and the Tibetan Plateau, to southern Siberia, Mongolia and western China. In the northern range countries, it also lives at lower elevations.

North American jaguar Jaguar population in North America

The North American jaguar is a jaguar population in North America, from the southwestern United States to Central America. This population has declined over decades.

South American jaguar

The South American jaguar is a jaguar population in South America. Though a number of subspecies of jaguar have been proposed for South America, morphological and genetic research did not reveal any evidence for subspecific differentiation.
