There are 11 species of skunk, two in Asia and nine in the Americas. All of them have the ability to spray a foul smelling chemical when threatened. The famous skunk spray is a mix of sulphuric chemicals, and skunks can spray accurately up to 15 feet. The stench is so powerful the skunk almost every animal leaves it alone, the sole exception being the Great Horned Owl which has almost no sense of smell.
