20+ Interesting Facts About Minks

1. Minks are carnivorous semiaquatic mammals native to the Northern Hemisphere. They are famous for their valuable fur, available in various dark and lighter colors.
2. Minks are primarily nocturnal animals that may also hunt during dusk and dawn. They belong to the weasel family, while their closest relatives are weasels, otters, polecats, and ferrets.
3. Minks and otters resemble each other, but they have visible differences. Minks are shorter (2 feet long) than otters (4 feet long), while their tails are short and bushy compared to long and slender tails in otters.
4. These mammals have two extant species, American mink and European mink. The American mink is larger, more aggressive, and more adaptable than their European counterparts. European minks have white patches on their upper and lower lips, while the white mark is only on the lower lip of American minks. 
5. The native range of the American mink is North America, while the European mink is present in many parts of Europe. However, American minks are now present outside their native range due to their introduction to various fur farms in Europe, Asia, and South America.
6. Sea minks were one of the first mammals to become extinct in North America after its colonization by Europeans. The extinction of sea mink took place sometime between 1860 and 1920 due to extensive hunting for its valuable fur. Before this event, there were two types of minks in North America, the sea mink and the land mink, now known as the American mink. However, scientists are not sure whether the sea mink was a separate species or a subspecies of the American mink. (Source)
7. American minks now inhabit several non-native areas in Europe and South America due to their voluntary or involuntary release from fur farms. They are invasive species in these areas and have caused the decline of European minks and other wetland animals.
8. European minks were once present almost everywhere in Europe, from the Urals to northern Spain. However, their numbers and range have reduced drastically due to human interference and the arrival of American minks. European minks have become one of the most endangered carnivores in Europe.

9. Minks are 12 to 20 inches long and weigh up to 2 kg. Farm minks can reach twice the size of wild minks due to better nutrition and the adoption of selective breeding techniques. Like many other mammals, male minks are larger than females.
10. Minks are generally solitary except during the mating period. Both males and females may mate with multiple partners. Female minks have a gestation period of 40 to 75 days, depending on the season. The range of their litter size is from two to eight young ones.
11. Female minks put their embryos on pause if they mate earlier than required. It enables them to give birth in spring, thus increasing the likelihood of survival of newborns. (Source)
12. Mink coats were at the peak of their popularity during the 1980s. However, their usage started to decline in the 1990s due to animal rights campaigns and new regulations. Recently, many countries and luxury brands have banned mink fur because of the fear of vaccine-resistant COVID-19 mutation in these mammals. (Source)
13. Mink oil resembles human sebum and acts as a moisturizer. Several brands use it in their cosmetic formulations to enhance the quality and complexion of human skin. (Source)
14. Wild minks usually have brown-colored coats. However, selective breeding in fur farms enables them to produce a range of colors, such as blue, black, white, sapphire, and pearl.
15. Minks are very territorial and may fight with other minks that enter their territories. They secrete a foul-smelling liquid from anal glands to mark their territory and as a defense against predators.
16. Minks have several physical features that assist in their semi-aquatic life. They use their semi-webbed toes and waterproof oily guard hairs to swim effortlessly.
17. Minks are carnivorous animals and eat small to medium-sized animals in their habitat. These include both land and aquatic animals, such as frogs, fish, crayfish, salamanders, voles, mice, aquatic birds, and rabbits. They locate the prey using their sharp vision and highly developed sense of hearing.
18. Minks live in burrows near a water source (streams, ponds, rivers, and ocean bays), rich in their food sources. They usually store extra food in their dens. Minks are excellent swimmers and can also climb trees.
19. Minks are excellent diggers, and their burrows contain several entrances. They sometimes use burrows dug by other animals, such as muskrats.
20. Unlike animals in the wild, minks in farms can transmit several deadly infections to humans. The risk is due to the high-density of these animals in a small enclosed space. Therefore, they can spread dangerous pandemics, such as SARS and avian influenza viruses. (Source)
21. Some large mammals and birds in their habitat hunt minks. These include coyotes, bobcats, foxes, and great-horned owls. The majority of these predators usually attack young minks. 
22. Minks can prove troublesome for farmers and homeowners due to their consumption of domestic animals and pets. They usually attack poultry (chicken and ducks), fish, and rabbits.
