Jaguar

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 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 the Western United States, 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. 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 American cultures, including those of the Maya and Aztec. The word 'jaguar' is thought to derive from the Tupian word yaguara, meaning 'beast of prey'. The word entered English presumably via the Amazonian trade language Tupinambá, via Portuguese jaguar. The specific word for jaguar is yaguareté, with the suffix -eté meaning 'real' or 'true'. The word 'panther' derives from classical Latin panthēra, itself from the ancient Greek pánthēr (πάνθηρ). In Mexican Spanish, its nickname is el tigre: 16th century Spaniards had no native word in their language for the jaguar, which is smaller than a lion, but bigger than a leopard, nor had ever encountered it in the Old World, and so named it after the tiger, since its ferocity would have been known to them through Roman writings and popular literature during the Renaissance. Onca is the Portuguese onça, with the cedilla dropped for typographical reasons, found in English as ounce for the snow leopard, Panthera uncia. It derives from the Latin lyncea lynx, with the letter L confused with the definite article (Italian lonza, Old French l'once).
