The Sea Mink, Neovison macroon, is an extinct North American member of the Mustelidae family. It is the only mustelid, and one of two mammalian carnivore species to have gone extinct in historic times, along with the Falkland Island Fox. It was significantly longer than the closely related American Mink (N. vison), and also larger and fatter, leading to a pelt that was around twice the size. The longest specimen recorded was said to be 82.6cm (32.5 in). The fur of the Sea Mink was said to be coarser and redder than the American Mink's, and give off a distinctive odour.
