Family & relatives: A true big cat in the genus Panthera, most closely related to the lion, tiger, and leopard; it is the only Panthera species native to the Americas.
How to spot it: A stocky, muscular cat with a coat of rosettes that have small spots inside them, distinguishing it from the leopard.
Its body & abilities
Size: About 1.1 to 1.85 meters in body length plus a tail of 45 to 75 cm, standing roughly 63 to 76 cm at the shoulder.
Weight: Adults weigh about 45 to 100 kg, making it the largest cat in the Americas and the third largest in the world.
Body & adaptations: A short, powerful body with massive jaw muscles and thick canines built to crush bone and shell.
Top speed: Can run up to about 80 km/h in short bursts, but is an ambush hunter rather than a chaser.
Strength: Has the strongest bite of any big cat relative to size, powerful enough to pierce a turtle shell or crocodile skull.
Senses: Excellent night vision and acute hearing suit its nocturnal hunting, and it can detect prey in murky water.
Growing up: Cubs are born with woolly, spotted fur and closed eyes, follow their mother while learning to hunt, and leave at one to two years.
Where it lives
Habitat: Favors dense tropical rainforest, swamps, and wetlands, and is strongly tied to rivers and water.
Where in the world: Ranges from Mexico through Central America to northern Argentina, with the stronghold in the Amazon basin.
Territory: Solitary and territorial, it marks and patrols home ranges that can span tens to over a hundred square kilometers.
What it eats
Diet: A powerful carnivore with the broadest prey list of any cat, hunting near water where it also drinks.
Favorite foods: Eats capybaras, peccaries, deer, caimans, turtles, fish, and more than 85 recorded prey species.
How it hunts: Unlike most cats, it often kills with a single bite through the skull, and readily swims to catch prey.
How it behaves
How it moves: A strong walker, superb climber, and one of the most capable swimmers among cats, at home in flooded forest.
When it is active: Active mostly at dawn, dusk, and night, resting in shade or near water through the heat of the day.
Family life: Solitary except for mating and mothers with cubs; it does not form groups and has no collective name.
How it talks: It can roar, and also grunts and makes a sawing 'coughing' call, marking territory with scent and claw scrapes.
Babies: After about 90 to 110 days of gestation, the female bears one to four cubs, usually two, and raises them without the male.
Its place in nature
Role in nature: A keystone apex predator with no natural predators as an adult; it shapes whole ecosystems by controlling prey populations.
Conservation: Listed as Near Threatened by the IUCN, declining from deforestation, hunting, and loss of prey.
Dangers: Mostly killed by people through hunting and retaliation for livestock loss, along with habitat destruction.
Life & legacy
How long it lives: About 12 to 15 years in the wild and up to around 23 years in captivity.
In our culture: A sacred symbol of power for the Maya, Aztec, and other ancient American cultures, often linked to rulers and gods.
Where to see it: Best seen in Brazil's Pantanal wetlands, and also in reserves across Central and South America and in major zoos.
Fun fact: The name jaguar comes from an Indigenous word often translated as 'he who kills with one leap'.
