The American Mink is a small, predatory animal with short legs and a thin body. They have rounded ears, a pointed snout and a thick furry tail that makes up one third of their total body length. Being nocturnal, Mink can see well at night, but not so well underwater. They will locate their prey above water before diving below. A combination of partially webbed toes and a slim body allows these semi-aquatic carnivores to move with speed and agility on water and land.
