Which mammal is the smelliest?

Skunks are mammals of the Mephitidae family. They are well-known for their propensity to squirt a powerful, unpleasant-smelling liquid from their anal glands. Skunks vary in appearance from black-and-white to brown, cream, or ginger, but they always have warning colors. Skunks are related to polecats and other members of the weasel family, but their closest cousins are the Old-World stink badgers.

As a protection against predators, this black and white critter sprays a foul-smelling, musky fluid. Most wild skunks spray as a protection strategy when they are hurt or assaulted. Its aroma is made up of chemicals that can be emitted by one or both of their anal glands. They can aim their glands at a target up to 15 feet (4.5 meters) away with incredible accuracy, but luckily for us, they tend to offer a little bit of early warning: to show anger or fear, they frequently stamp their front paws, knead the ground like a cat, and keep their tail upright.
