The Jaguar has no known predators besides man. They also have no other
animals competing against them for food or land, besides man again. Humans
are destroying their habitat daily by cutting down rainforests and not
preserving the land. Humans are also hunting them for their fur, even though
they are endangered. The
funny thing is that many people think of Jaguars as fierce predators who
would eat a human if they got the chance. However, there has been very few
reported cases of Jaguar trouble ever and far fewer deaths. In one village's
chronicles they documented Jaguars coming out of the cover to play with the
children of the village.
