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"). It is also called the Glutton or
Carcajou. Some authors recognize two subspecies: the Old World form
Gulo gulo gulo and the New World form G. g. luscus. A third
subspecies limited to Vancouver Island (G. g. vancouverensis) is
also occasionally described. However craniomorphic evidence
suggests that the Vancouver Island wolverines are properly included
within G. g. luscus.
