Zebras use their stripes to confuse animals that might try to hunt them. Tigers use their stripes so they can blend into long grass, which helps them hunt. Skunks have stripes, but they aren't hiding.
The first thing you think of when you hear the word "skunk," is probably their smelly, stinky scent that they can spray at animals that frighten them. Most people know that skunks have this stinky spray. A lot of animals know it too. That's why when most animals see a skunk, they recognize the stripes on its back, and think, "I don't want to get sprayed!" The skunks smell so bad, animals would rather be hungry than attack them!
Usually, the only animals that attack skunks are the ones with a poor sense of smell, like owls.
