The Wolverine (Gulo gulo) is the largest species of the Mustelidae family, it is also called the Glutton or Carcajou. It is a stocky and muscular omnivorous (but largely carnivorous) animal with brownish-black hair that can weigh up to 15kg (male), and is 70-90cm long with a 20cm tail. Its overall appearance looks somewhat like a small bear with a long tail.
It is found in arctic regions such as northern Canada or Siberia. It is considered to be very strong and ferocious and has been known to kill animals as large as caribou.
The University of Michigan's sports teams are named after the wolverine.
