Why Skunks evolved their smelly spray?

The most notorious of all stink bombing critters is the skunk. It is a striking black-and-white animal found only in America (the stink badger found in a few Southeast Asian islands is a relative). It can afford to strut about in a natty suit because it has a not-so-secret weapon.

It pays not to get within 2 metres (10 feet) of a skunk. That’s the distance it can spray an incredibly evil-smelling oily liquid from scent glands in its backside right into your face. Skunk spray is full of sulphur-containing chemicals that temporarily blind you and make you choke. The smell is very difficult to get rid of.

Predators avoid skunks like the plague allowing it to go peacefully about its nocturnal foraging even though it stands out like a beacon.
