Jaguar

The jaguar (Panthera onca) is the largest cat in the Americas and the only extant member of the genus Panthera native to the Western Hemisphere. Stockier and more powerfully built than a leopard, it is built for ambush rather than pursuit, with a bite force strong enough to pierce turtle shells and caiman skulls directly through the braincase. Jaguars are highly adaptable and occupy a wide range of habitats, from the dense rainforests of the Amazon Basin and the wetlands of Brazil's Pantanal to dry forests, grasslands, and scrublands across Central and South America.

As an apex predator, the jaguar regulates prey populations and, through its movement across large territories, connects fragmented forest patches in ways that support broader biodiversity. The IUCN Red List classifies it as Near Threatened, with populations declining across much of its range. Deforestation is the primary driver of habitat loss, while retaliatory killing by ranchers protecting livestock remains a persistent and widespread threat. The jaguar has been eliminated from roughly 40 percent of its historic range, according to the IUCN, with the stronghold populations now concentrated in the Amazon and the Pantanal.
