Staff at Nordens Ark in Sweden finally got a glimpse of their newest residents, three Wolverine pups. The pups, born on February 21st, recently emerged from their mother's den; where they spent the first six weeks of their lives completely dependent on their mother.

Wolverines have a fairly small captive population of around one hundred individuals internationally. Since Wolverines are considered to be difficult to breed in captivity, and are associated with high infant mortality, this is a very important birth for the captive population. This is the second litter for the mother. She proved to be an excellent mother to her first litter of pups, so keepers are optimistic about the outlook for her newest batch.

Wolverines are medium sized predators. They are classified in the same family as Weasels, and are the largest species in this grouping. They are ferocious predators that are known to take down prey several times their own size. Native across the Northern Hemisphere in North America, Europe and Asia, Wolverines have adapted to a wide range of habitats. They are currently listed as species of "least concern" by the IUCN due to relatively large population numbers. Despite this, in February of 2013, the US Fish and Wildlife Service proposed give the species protection under the Endangered Species Act due to habitat loss as a result of global climate change.
