Name: The Beautiful, Powerful Jaguar 89b 89

What beautiful cat lives in North and South America and is bigger and tougher than a leopard or mountain lion? If you said jaguar, you're right. The only cat species that are larger are the tiger, the African lion and the very endangered Asiatic lion.

Most jaguars are orange or tan with black rose-shaped spots

(rosettes). However, there is also a solid black jaguar. Black jaguars have spots, too, but their spots are hard to see except when in bright sunlight.

The jaguar's coloration serves as camouflage. Lighter colored jaguars live in more open grassland and forest. Here, their marking help them blend in among the vegetation and shadows. Black jaguars, meanwhile, blend in better in the darkest forests and jungles.

Like tigers, jaguars live alone most of their lives. Baby jaguars are born in litters of one to

four and stay with their very protective mother for two years while they learn to hunt. Then they leave to establish their own territories, marking it with their waste or by clawing marks in trees.

Also like tigers, jaguars love water. They'll sit half-submerged in a cool rainforest stream or

pond waiting for prey. Sometimes jaguars will even climb trees to await unsuspecting prey wandering below.

They'll catch water animals like caiman (a relative of alligators and crocodiles), fish, frogs and turtles. Other times, they'll hunt on land. They'll pounce on tapir, peccaries, capybara or deer with one quick leap. A jaguar's bite is so strong; it can even chomp through tortoise shells. They've even been observed using their jaws to drag heavy prey for over a mile.

People often confuse leopards with jaguars. Both are beautiful,

spotted cats. However, there are several important differences. Leopards live in Asia and Africa, while jaguars are native to the Americas. Also, jaguars are much bigger. They have heavier chests and legs, and their larger heads have more powerful jaws.

While Jaguars were once fairly abundant, they are currently endangered. Mining, farming and other development have destroyed much of their wild habitat. Today some of their habitat is protected. However, these beautiful cats are still illegally hunted for their fur and because they are a threat to ranchers' livestock.
