Wolverine Animal Facts: Species and Ancestry | 6-10
6. Wolverine is closely related to the tayra (belongs to weasel family) and martens (belongs to the Mustelidae family).
7. There are two subspecies of wolverine. They are:
Gulo gulo gulo from the Old World (Asia, Europe and Africa combined is called Old World).
Gulo gulo luscus from the New World (North America, South America, Australia and regions present near Australia combined are referred to as the New World).
8. However, some scientists note 4 more subspecies in North America, two of which are:
Gulo gulo vancouverensis – It is limited to Vancouver Island.
Gulo gulo katschemakensis – It is limited to Kenai Peninsula.
9. Present accepted taxonomy recognizes the 2 continental subspecies (Gulo gulo gulo and Gulo gulo luscus) or the species Gulo gulo as a Holarctic taxon (Holarctic is a biogeographical region which includes the Arctic, North America, North Africa, entire Europe, northern parts of Asia, North Mexico etc.)
10. Recent genetic studies prove that the wolverines of North America came via Beringia during the last glaciation period.
Wolverine Animal Facts: Physical Appearance | 11-16
12. It resembles more to a bear compared to any other species of the family Mustelidae.
13. Its legs are short. However, with its large paws which contains five claws each and its plantigrade posture (placing toes and metatarsals flat on the ground and that is the way humans walk), it can climb cliffs, trees, peaks covered with snow, etc. without any difficulty.

17. Likewise, the weights of the males and females vary with geographical variation.
18. It is believed that Eurasian wolverines are larger and heavier than the North American counterparts.
19. Their fur is thick, oily and dark. The fur is hydrophobic meaning it doesn’t get wet when it comes in contact with water. The fur being hydrophobic, it is resistant to frost as well.
20. A silvery facial mask or some white patches of fur is present in some wolverines.

Wolverine Animal Facts: Habitat, Distribution and Home Range | 24-28
24. Wolverine is a solitary animal. It lives in the arctic, boreal and alpine regions i.e., they are widely seen in Siberia, Alaska, Fennoscandia, European Russia, Russian Far East, Baltic countries, Mongolia, etc.
25. Their presence in states like Michigan, Sierra Nevada, Washington is seen in the recent times again.
26. At present, the New World wolverines are present in Canada and Alaska.
27. The wolverine has a big home range. Male wolverine’s home range is around 620 square kilometers and female wolverine’s home range is around 130 to 260 square kilometers.
28. A male’s range consists of multiple ranges of females (owing to the smaller home ranges of female wolverines).
Wolverine Animal Facts: Habitat, Distribution and Home Range | 29-32
29. The home ranges of both males and females mostly don’t overlap with the home ranges of the same sex.
30. The home ranges are marked with the help of anal scent glands. The scent is used for sexual signaling and marking territory.
31. In the month of February, female wolverines burrow into snow to make dens which can be used during childbirth and till the kits (kids of wolverine) wean.
32. Wolverines don’t inhabit few areas which are called snowmelts. Snowmelt is an area where the runoff is produced due to the melting snow.
Wolverine Animal Facts: Reproduction, Kits and Lifespan | 33-37
33. Males form lifelong relationships with either two or three female wolverines. The male which forms the relationship occasionally meets the females.
34. Wolverine mates in summer months. However, implantation of embryo in the uterus takes place only in early winter.
35. Females generally delay the implantation till early winter. They may even delay the implantation if the food is scarce.
36. Gestation period lasts for about 30 to 50 days. Two to three kits are born in a litter. They are born in the spring. They are weaned at 10 weeks of age in mid-May.
37. Kits, when born, weigh only few grams of weight, are around 5 inches long and they have snow-white fur.
Wolverine Animal Facts: Reproduction, Kits and Lifespan | 38-42
38. At around 6 weeks their fur starts getting darker and they develop varied and unique patterns of color of fur on their chest, face and neck.

40. Lifespan of a wolverine is generally 15 to 17 years in captivity and 8 to 10 years in the wild.
41. Fathers and kits share a harmless relationship. Fathers meet with their kits till they are weaned, when they are six months old.
42. Some kits may connect with their fathers and travel with them for some time.
Wolverine Animal Facts: Hunting and Eating Habits | 43-47
43. Wolverine is an omnivore (eats both plants and animals) and an opportunistic hunter or primary scavenger, meaning it feeds on corpses.
44. It is called primary scavenger because carrion (decaying meat) is the primary source of food for a wolverine during winter months and early spring.
45. Wolverines may find carrion by themselves or take it from other predators by force, or eat the leftovers after the main predator (which actually killed the prey) leaves.
46. They follow trails of lynx and wolves so that they can scavenge on the leftovers.
47. Whether it is carrion or a live prey, they eat voraciously hence the name “glutton” which is also the basis of its scientific name.
Wolverine Animal Facts: Hunting and Eating Habits | 48-52
48. Some say that gluttony is an adaptation of scarcity of food during winter.
49. Though they scavenge, their predatory skills cannot be taken for granted. Wolverines are extremely strong for their size just like most of the species in their family.
50. Small to medium sized animals become prey to wolverines. It must be noted that they have the capacity to kill prey larger than their size.
51. Porcupines, chipmunks, beavers, moles, voles, shrews, roe deer, lemmings, mule deer, goats, moose, squirrels, elk etc., are some of the few preys of wolverine.
52. Smaller animals like mink, foxes, coyote, Eurasian lynx, wolf pups, martens etc., also become prey sometimes.
Wolverine Animal Facts: Hunting and Eating Habits | 53-57
53. Wolverine is a very shrewd animal. It preys on the animals which are caught in trap, newborn animals or juveniles, weak or immobilized animals.
54. It also feeds on birds, their eggs, roots, berries, seeds, larvae of insects etc.
55. Old World wolverines are more active in hunting and catching prey than New World wolverines.
56. As said earlier, wolverine follows the trails of wolves for the prey. Hence, the population of wolves effects the population of wolverines.
57. They cache the prey when the prey is plenty. This caching is seen particularly in females during winter (pregnancy time) and early spring (childbirth time).
Wolverine Animal Facts: Predators, Threat and Conservation Status | 58-65
58. Wolves, the ones that give them food (indirectly though), are the ones who are natural predators of wolverines.
59. Wolves forced the wolverines to abandon the areas which were usually common to them.
60. Wolverines defend their preys from other larger predators like wolves, mountain lion, bears etc.
61. Grey wolf is the greatest predator of wolverine in both Eurasia (Old World) and North America (New World).
62. There are accounts of bears killing and eating wolverines. There is a different account of a wolverine killing a polar bear, but this may be false.
63. The exact population of wolverine remains unknown all over the world. As of today, IUCN lists wolverine as Least Concern (LC).
64. Humans are the biggest threat to wolverines. Hunting, trapping, human development etc. are some of the main causes of the decreasing numbers of wolverine. Climate change is another reason which threatens the population of wolverines.
65. We said that the fur of wolverine is resistant of water and frost. Humans hunt wolverines for their fur that is used as lining in parkas (type of jacket with a hood) and jacket.
Wolverine Animal Facts: In Culture of North America | 66-68
