Molina's hog-nosed skunk range

The Molina’s Hog-Nosed Skunk, Conepatus chinga, is similar to the common skunk with scent glands used to spray an odorous liquid to offend potential predators. However, they also have a resistance to pit viper venom to defend themselves in the environment that they live. They also have distinct thin white markings and a distinct pink, hog-like, fleshy nose.

Habitat

The Molina’s Hog-Nosed Skunk’s native range is throughout mid to southern South America, Chile, Peru, northern Argentina, Bolivia, Paraguay, Uruguay, and southern Brazil.[2] The mammal is therefore associated with temperate regions and open areas, mainly described as the Pampas biome[3] and preferring to live in open vegetation, shrub forest and rocky sloped areas.[2]

Population and Distribution

Typically they will live alone in an average home range size of about 1.66 individuals/km^2 with some overlapping and about six skunks per 3.5 km^2.[4] Although living in mostly solitary areas, the skunks will come together temporarily for mating purposes.[2]

Diet

Foraging mainly at night, the skunk is omnivorous eating birds, small mammals, eggs, insects, leaves, and fruit. The tooth morphology in the molina’s hog-nosed skunk, is different than most mammals in that their teeth are adapted to their omnivorous diet with grinding being the main function of the carnassial apparatus.[5]

Conservation Status

The skunk is listed as “Least Concerned” according to the IUCN Redlist. The main threats of the skunk are increased habitat destruction and fragmentation[6] from over exploitation of humans and grazing of agriculture. The skunk is also affected by the planning of new roads and road-kills. Due to improper planning, habitat destruction, and fragmentation, the skunk has started living around man-made structures and along fences and buildings.[6]
