At the Detroit Zoo
Visitors to the "wolverine state" can hail to its two victors – male Jigi and female Anna – at their American Grasslands habitat. Jigi, born in 2001 at the Minnesota Zoo, came to the Detroit Zoo in 2002. He has a kind and friendly personality, making it easy for Anna to boss him around. Born in 2007, Anna arrived at the Zoo in 2012 with a breeding recommendation. She is acrobatic, and can be seen doing "parkour" around her habitat, jumping and propelling herself off of surrounding objects and trees.

The wolverine has small, round ears, a broad head and a long, bushy tail. It has dark brown fur with tannish-colored stripes on both sides of its body (running from its shoulders to its tail). It is a stocky and muscular member of the weasel family that more closely resembles the bear than other weasels. Its wide feet helps it to travel over various terrains (such as snow), and its long, non-retractile claws and powerful jaws help it rip into its food.

A wolverine's fur is hydrophobic, which means that the fur is resistant to the elements such as frost and snow.

Kits are born white so they are able to be camouflaged in the winter.  Their white natal hair eventually turns brown as the kits mature.
