The Jaguar (Panthera onca) is the largest of the six species of cats found in the forests of Guyana. (The other five big cats are the cougar, jaguarundi, ocelot, margay and oncilla). It feeds on agoutis, labba, deer, turtles, fish, wild pigs and capybara. It reaches body lengths of 1.5-2 m (5-6 feet), and a height of 0.8-1 m (2.5-3 feet) at the shoulder. Female jaguars can weigh 50-100 Kg (100-200 pounds, while males weigh 60-120 Kg (125- 250 pounds). Jaguars are generally tan with black rings and dots, however some jaguars - called black panthers - are completely black in coloration. Jaguars are a sign of a healthy forest ecosystem. Jaguars are solitary creatures and tend not to mew or roar like other cats. Jaguars are an endangered species.
