How the Jaguar hunting


The jaguar is most active at dusk and night. Being a short distance runner fast enough hunting their prey mainly on the ground. It is a great swimmer and can even cross rivers with a width of several kilometers. 
The jaguar goes over 50% of their time hunting and, then, can cover a distance of 3 or 4 miles a day and even during drought when there is little food. The jaguar has a fixed territory can cover up to 40 km2. 
The jaguar is considered an opportunistic carnivore and its diet depends on the density and prey availability. More than 85 species have been recorded in the jaguar diet (Seymour 1989). Large dams such as peccaries, tapirs and deer are their favorites, but also feeds on other mammals such as monkeys and sloths, always depending on their availability at each location. Keep in mind that such large herbivores are fewest in the jungle than in open areas, which are designed to form large groups, this is one of the causes that make a difference in their feeding areas in forests and open. Also hunts frogs, turtles, snakes and even alligators can attack, but are significantly bigger than him. It also eats fish and birds have their nests on the ground. 
In areas inhabited by jaguars and cattle there are cases that hunt prey to these easy due to the scarcity of natural prey and the passivity of these new dams. 
The jaguar eats small prey whole and immediately. When hunting large prey, eat some and removed for a nap and then return later to finish. If an animal kills a jaguar out of the forest takes you inside. Sometimes even drags its prey across the River. 
The aperture of the mouth known is at an angle of about 65 to 70 °. This feature coupled with its strong canines are vital to hunt him: indeed, the art of hunting is stalking jaguar, culminating in a sudden leap and a nape bite to break the cervical vertebrae or the skull of his victim. The drilling of the skull only the Jaguars made from big cats to kill their prey. According to some authors (Emmons (1987)) large head and big strong dogs could be an adaptation to open cracks in animals 'armored' such as some reptiles and turtles.
