The Wolverine (Gulo gulo) is the largest land-dwelling species of the Mustelidae or weasel family (the Giant Otter is largest overall), and is the only species currently classified in the genus Gulo (meaning "glutton"). The Wolverine is a stocky and muscular animal, considered carnivorous but known on occasion to eat plant material. The wolverine is still trapped for its fur in some parts of its range. Since 2003 Canada has classified its eastern population of Wolverines as "endangered.
