The American mink (Neovison vison) is a semiaquatic species of mustelid native to North America, though human intervention has expanded its range to many parts of Europe and South America. Because of range expansion, the American mink is classed as a least-concern species by the IUCN.[1] Since the extinction of the sea mink, the American mink is the only extant member of the genus Neovison. The American mink is a carnivore which feeds on rodents, fish, crustaceans, frogs, and birds.
