Mink

The European mink (Mustela lutreola), also known as the Russian mink, is a semi-aquatic species of Mustelid native to Europe. It is listed by the IUCN as Critically Endangered due to an ongoing reduction in numbers, having been calculated as being more than 50% over the past three generations. European mink numbers began to shrink during the 19th century, with the species rapidly becoming extinct in some parts of Central Europe.
