Panthera onca
The jaguar is the third-largest feline after the tiger and the lion, and the largest in the Western Hemisphere.

This spotted cat resembles the leopard although it is usually larger and sturdier and its behavioral characteristics are closer to those of the tiger. While dense rainforest is its preferred habitat, the jaguar will range across a variety of forested and open terrain. It is notable as a feline that enjoys swimming. The jaguar is a solitary, opportunistic, stalk-and-ambush predator at the top of the food chain. It is a keystone species, playing an important role in stabilizing ecosystems and regulating the populations of the animals it hunts. The jaguar is a near threatened species and its numbers are declining. Threats include habitat loss and fragmentation. While international trade in jaguars or their parts is prohibited, the cat is still frequently killed by humans, particularly in conflicts with ranchers and farmers in South America.
