Jacquar tiger from Khao Khiew Open Zoo, Chonburi, Thailand. It has been very difficult to spot tigers at the National Parks these days due to very few numbers of tigers exist in Thailand. The current range of jaguar spans southern part of North America (United States and Mexico), across Central America till almost half of South America (North of Argentina, South of Paraguay). The jaguar is the third-largest feline after the lion and tiger. This big cat belongs to the Panthera genus, class Mammalia, and in fact in the Americas, it is the only Panthera species that is found. Typically, jaguars weigh between 100 to 250 pounds and live for 12 to 15 years in the wild. An adult is 5 to 8 feet in length including the tail. Their beautiful brown-yellow coat with shades of red and black and the numerous spots over the body are close to those seen on the body of a leopard. But jaguars have larger and fewer spots as compared to a leopard. They also have a broad head and an extremely powerful jaw.
