Jaguars are ambush hunters. They have a spotted coat that helps them blend into their surroundings in the habitats they live in. They lay hidden and move close to their unsuspecting prey. Once close enough, they pounce and tackle their prey. The use the standard bite the throat & suffocate prey technique to kill their prey. They also use a more unique way wherein they bite the skull between the ears of their prey (esp. Capybara's) with their canine teeth piercing the prey's brain. They literally crack the preys skull. This stands testimony to the impressive bite force the Jaguar has in its strong jaws.

It should take that long at all, it's all down to chance but it fairly quick.
