Through Americas, Predation and Fossil

The modern jaguar's ancestors probably entered the Americas from Eurasia during the Early Pleistocene via the land bridge that once spanned the Bering Strait. The oldest jaguar fossils found in North America date to between 0.85 to 0.82 million years ago. Today, the jaguar's range extends from the Southwestern United States across Mexico and much of Central America, the Amazon rainforest and south to Paraguay and northern Argentina. It inhabits a variety of forested and open terrains, but its preferred habitat is tropical and subtropical moist broadleaf forest, wetlands and wooded regions. It is adept at swimming and is largely a solitary, opportunistic, stalk-and-ambush apex predator. As a keystone species, it plays an important role in stabilizing ecosystems and in regulating prey populations.

The jaguar is threatened by habitat loss, habitat fragmentation, poaching for trade with its body parts and killings in human–wildlife conflict situations, particularly with ranchers in Central and South America. It has been listed as Near Threatened on the IUCN Red List since 2002. The wild population is thought to have declined since the late 1990s. Priority areas for jaguar conservation comprise 51 large areas inhabited by at least 50 breeding individuals, called Jaguar Conservation Units. They are located in 36 geographic regions from Mexico to Argentina.

The jaguar has featured prominently in the mythology of indigenous peoples of the Americas, including those of the Aztec and Maya civilizations.

Etymology

The word "jaguar" is possibly derived from the Tupi-Guarani word yaguara meaning 'wild beast that overcomes its prey at a bound'. Because jaguar also applies to other animals, indigenous peoples in Guyana call it jaguareté, with the added sufix eté, meaning "true beast". "Onca" is derived from the Portuguese name onça for a spotted cat that is larger than a lynx; cf. ounce. The word "panther" is derived from classical Latin panthēra, itself from the ancient Greek πάνθηρ (pánthēr).

In North America, the word is pronounced with two syllables, as , while in British English, it is pronounced with three, as .
