Jaguar (image via: Awesome-Desktop/S.K.)
The Jaguar (Panthera Onca) is the third-largest of the four big cats in the genus Panthera, and the only living member native to the western hemisphere.
Growing up to 160 kg (350 lb), Jaguars are distinguished by rosette-emblazoned fur, comparatively short tails and an exceptionally powerful bite that enables them to successfully prey on armored reptiles such as caimans and turtles.

Jaguars are stated to be Near Threatened by the IUCN and while their current range is roughly half of what it once was, these often solitary big cats can still be found from southern Arizona in the United States down to Paraguay and northern Argentina.
