Anal Glands

Two-month-old Striped Skunks Can Spray!

7-15-15 striped skunk2 058The answer to yesterday’s mystery photo is a lot less original than many of your guesses, all of which could have been true, given my natural curiosity. I am embarrassed to admit that it was the oily, yellow spray of a young striped skunk that covered my spectacles (and my entire head, arms and camera) – even with ample warning, I chose to persevere in order to get the perfect picture. Unfortunately, the skunk was a lot more successful at his mission than I was at mine.

There is a reason why coyotes, foxes and most predators (one exception is the great horned owl), including most sane photographers, keep their distance from striped skunks. Whether newborn or several years old, skunks are capable of using their musk-filled anal glands to ward off anything that threatens them. Skunks are generally reluctant to spray, however, as they only have a few teaspoons (half an ounce) of musk in their glands, and once their supply is depleted (five or six sprays), they are defenseless for about 10 days, while it builds up again. Hence, plenty of warning is given in the form of stomping front feet, erect hair, raised tail, and chattering before a skunk contracts the muscles surrounding its anal glands and shoots a pungent, yellowish spray as far as ten feet away. Only a fool would not heed the warning given…and be forewarned – a skunk’s aim is surprisingly accurate.

The organic compounds that make the smell of skunk spray so offensive are called thiols (mercaptans). Thiols are also found in garlic and onions, and form parts of the keratin in hair. If your dog or you happen to be at the wrong end of a skunk’s partially everted anus, the best combination to neutralize the musk smell is 1 quart of 3% hydrogen peroxide, ¼ cup of baking soda, and 1 teaspoon of liquid dish soap.
