The striped skunk (Mephitis mephitis) belongs to the order Carnivora and the family Mephitidae, a group distinguished by their well‑developed anal scent glands. It occupies a broad range across most of North America, extending from southern Canada through the United States into northern Mexico. Within this range the species inhabits a variety of ecosystems, including deciduous and coniferous forests, grasslands, agricultural fields, and increasingly urban and suburban areas where it exploits human refuse. Adults are easily recognized by their black fur marked with a bold white dorsal stripe that may be continuous or broken, and a bushy tail that can reach 20 cm. The skunk’s most famous adaptation is its ability to spray a foul‑smelling musk when threatened, a defensive mechanism that deters most predators. Although listed as Least Concern by the IUCN, the species plays a vital role in controlling insect populations and dispersing seeds, making it an important component of North American ecosystems.

Striped skunks are primarily solitary and nocturnal, emerging at dusk to forage and returning to dens before sunrise. Home ranges vary from 0.5 to 2 km² for females and up to 4 km² for males, with overlapping territories tolerated as long as scent markings are respected. Individuals communicate through a combination of vocalizations—such as hisses, growls, and chirps—and extensive scent marking using urine and anal gland secretions. These chemical signals convey information about reproductive status, individual identity, and territorial boundaries. During the winter months activity may decline, but skunks do not hibernate; instead they rely on stored fat reserves and may enter short periods of torpor. Aggressive encounters are rare, as the threat of a spray usually resolves conflicts without physical fighting.

The striped skunk is an opportunistic omnivore, consuming a highly varied diet that reflects seasonal availability. Invertebrates such as beetles, grasshoppers, and earthworms constitute the bulk of the diet during spring and summer, while small vertebrates—including rodents, amphibians, and bird eggs—are taken opportunistically. Plant matter, particularly berries, nuts, and agricultural crops like corn and soybeans, provides essential carbohydrates, especially in autumn when animal prey declines. Skunks also scavenge carrion and readily exploit human food waste in urban settings, which can increase exposure to toxins and disease. Daily food intake averages 200‑300 g, and individuals may travel up to 2 km each night while foraging. Their keen sense of smell and tactile whiskers aid in locating hidden prey beneath leaf litter and soil.

Sexual maturity is reached at about 10 months for both sexes, though females typically breed for the first time in their second year. The breeding season occurs from February to April, with females entering estrus for a brief 2‑3 day window. After mating, gestation lasts 60‑70 days, culminating in the birth of 4‑7 kits in a well‑lined underground den. Newborns are altricial, blind and hairless, and are nursed for approximately 8 weeks. Both parents contribute to nest defense, but maternal care dominates; the mother provides all nourishment and teaches kits foraging skills. Kits are weaned by 10 weeks and begin to disperse from the natal den at 12‑14 weeks, establishing their own territories by the following spring.

The IUCN classifies the striped skunk as Least Concern, with an estimated global population of several million individuals and a stable trend. Nevertheless, localized threats persist. Road mortality is a major source of mortality, accounting for up to 30 % of adult deaths in some regions. Habitat fragmentation from urban development reduces suitable foraging and denning areas, while agricultural intensification can expose skunks to rodenticides and other pesticides. Persecution by humans—often due to misconceptions about disease transmission—results in trapping and illegal killing. Emerging diseases such as canine distemper and rabies also pose risks, especially in densely populated areas. Conservation measures focus on preserving habitat connectivity, implementing wildlife crossing structures, and public education to reduce unnecessary persecution.

• The skunk’s spray can travel up to 3 meters and remains potent for weeks.
• Striped skunks have a low body temperature (≈37 °C) and a slow metabolism, allowing them to survive on limited food during winter.
• Their anal glands can store up to 15 ml of musk, which is a mixture of sulfur‑containing compounds.
• Skunks are immune to the pain of their own spray, a rare physiological adaptation among mammals.
• In some Native American cultures, skunk fur was used in ceremonial regalia for its distinctive pattern.
