How do skunks spray their stink?

Skunks are part of a family of animals called mustelids, along with weasels, badgers, and otters. All of these animals produce a unique, musky smell, but where stink is concerned, the skunk reigns supreme. They can spray a super-smelly liquid from their butts at anything that scares them.
