Which of these animals sprays a terrible scent as a defense mechanism?

Skunks are one animal most people are very familiar with, both for their recognizable appearance and because of their foul-smelling but very effective defense mechanism. The skunks we are familiar with are more specifically called striped skunks, and they are one of several kinds of skunks. There are also spotted skunks, hooded skunks, and hog-nosed skunks. But of all the skunk species, the striped skunk is the only one native to Illinois.
