The name "striped skunk" comes from the distinctive pattern of white stripes that run along the back and sides of their body. These stripes help to warn predators and potential threats of the skunk's ability to spray a foul-smelling musk as a defense mechanism.
The term "normal skunk" is not a widely used term and doesn't refer to any specific variation or subspecies of skunks. It likely refers to the common striped skunk as they are the most well-known and widely distributed species of skunk.
