Pathera Onca, the Jaguar is the only New World Mammal amongst the four big cats of the Panthera genus. Ancestry is shared with the other big cats, with the closest genetic resemblance being to the leopard. Chromosomal analysis suggests the species originated somewhere between 300,000 to 500,000 years ago. Three subspecies are generally recognized based on geographic distribution - the Peruan, Mexican and Paraguan Jaguar.



Coloration is usually yellowish, with variations towards red and black. The coat is covered by rosettes having a pattern unique to each individual. Stark color variations do exist, with some Jaguars being totally black or white. The former are often incorrectly referred to as 'black panthers'. Appearance varies also on the habitat of the animal. Usually denizens of the dense forests have darker coats to aid them in conditions of low lighting, whereas Jaguars of relatively open plains have a lighter coloration to assist in their camouflage. These animals are also considerably bigger than their jungle counterparts since they have to tackle larger prey animals.

With powerful limbs, rounded skull and a robust physique, the Jaguar is a study in strength. Pound for pound it is one of the strongest land mammals. Its jaw strength goes unrivaled amongst all big cats. The great strength in canines and jaw bones has in fact enabled the Jaguar to practice a mode of killing most frightful among all predators of land - whilst capable of the usual neck bite and strangulation technique of big cats - the Jaguar prefers to kill its prey by a bite through its skull! The devastating bite is delivered between the ears of the prey as its teeth pierce the skull to enter the brain. The caiman is hunted in this manner as is the tortoise whose shell is cracked with ease by the great cat. At times the Jaguar may prefer to crush the cervical vertebrae or simply kill by a tremendous blow from its paw.

At stalking, Jaguar has no peer. Designed for stealth and a powerful pounce, Jaguar is considered as the best ambush hunter in all of animal kingdom. Its remarkably silent approach towards prey is simply incredible to watch. The other outstanding feature is its terrific hunting prowess in water. With a prey base from baby alligators to fish, Jaguar's aquatic hunting abilities are the best among land predators. Yet another remarkable weapon in the Jaguar's arsenal is the superb climbing ability of the heavily muscled cat - that enables it to prey on surprised monkeys and birds and carry prey as big as cattle to tree tops to avoid rising flood levels, using its great strength.

Territorial and solitary animals, adults meet solely for courtship. Mating continues year round and after a gestational period of three and a half to four months, two to four cubs are born. The females are highly protective of the defenseless young and roar frequently to warn other animals away. Maturity is reached at two years of age, by which time Jaguars are able to hunt on their own and establish their territory. Lifespan is the longest among big cats with ranges of up to 15 years in the wild and 25 years in captivity.
