Jaguar is one of the big cats which has the ability to roar and is the only Panthera species found in America. The unique feature of this species is the rosette-shaped spots in their body. A Jaguar looks almost similar to a leopard as both have the similarity of the spots in their body but Jaquar has smaller spots and a shorter tail compared to latter.
This spotted cat most closely resembles the leopard physically, although it is usually larger and of sturdier build and its behavioral and habitat characteristics are closer to those of the tiger. While dense rainforest is its preferred habitat, the jaguar will range across a variety of forested and open terrain. It is strongly associated with the presence of water and is notable, along with the tiger, as a feline that enjoys swimming. The jaguar is a largely solitary, stalk-and-ambush predator, and is opportunistic in prey selection. It is also an apex and keystone predator, playing an important role in stabilizing ecosystems and regulating the populations of prey species. The jaguar has an exceptionally powerful bite, even relative to the other big cats. This allows it to pierce the shells of armoured reptiles and to employ an unusual killing method: it bites directly through the skull of prey between the ears to deliver a fatal bite to the brain.
Like all cats, the jaguar is an obligate carnivore, feeding only on meat(click on the link to see a video). It is an opportunistic hunter and its diet encompasses 87 species. The jaguar prefers large prey and will take deer, capybara, tapirs, peccaries, dogs, foxes, and sometimes even anacondas and caiman. However, the cat will eat any small species that can be caught, including frogs, mice, birds, fish, sloths, monkeys, and turtles; a study conducted in Cockscomb Basin Wildlife Sanctuary in Belize, for example, revealed that jaguars there had a diet that consisted primarily of armadillos and pacas. Some jaguars will also take domestic livestock, including adult cattle and horses.
