Week Eighteen (Final Post): Jaguar

Common Name: Jaguar

Scientific Name: Panthera onca


Fun Fact: The Aztecs both feared and admired the jaguar. One of their elite warrior units was named for the animal, and the black jaguar was also the symbol of one of their most important gods, the darkly powerful Texcatlipoca.

Domain: Eukaryota

Kingdom: Animalia

Phylum: Chordata

Class: Mammalia

Order: Carnivora

Family: Felidae

Genus: Panthera

Species: P. onca

Description: Jaguars are stocky and muscular cats with heavyset features. Their fur is golden-brown and may contain hints of red. Their bodies are covered in black rings and spots. The all-black variety associated Texcatlipoca is quite common and is known as melanism—somewhat of an opposite to albinism. Jaguars may grow to around six feet in length with an additional thirty inches of tail and weigh 264 pounds. They are similar in appearance to their Old World cousins the leopards, but they are found exclusively in the Americas and are shorter and stockier in build.

Environment: Jaguars are native to South and Central America and are the largest of the New World cats. Their preferred habitat varies from forest to semi-desert but must include a nearby area of water for drinking and swimming. Poaching and habitat destruction have restricted the range of these animals.

Reproduction & Development: Jaguars reproduce sexually and females give birth to litters of 1-4 live cubs after a gestation of 93-105 days. The mother cares for her litter by herself; the cubs are weaned by about six months of age and become sexually mature at two to four years. Jaguars can live for up to 24 years.

Nutrition: Jaguars are carnivorous predators at the top of the food chain. Despite their skill at swimming, they mainly hunt on land. Their preferred prey includes various medium-sized herbivorous mammals such as peccaries, capybaras, and tapirs. Jaguars do make exceptions to the rule of terrestrial meat; they may catch fish and have even been known to kill and eat crocodiles.
