There are two living species referred to as minks: the American mink and the European mink. The extinct sea mink is related to the American mink, but was much larger. All three species are dark-colored, semiaquatic, carnivorous mammals of the family Mustelidae, which also includes weasels, otters and ferrets.

They use restrictor plates strictly as a safety matter so the car does not get thrown into the air because of all the air.
