Mustela Erminea is a scientific term for the weasel species that is also known as stoat or short-tailed weasel. These small carnivorous mammals are native to Eurasia and North America and known for their white winter coats that turn brown in the summer. The word stoat is often used to refer to the species, especially in the UK, while in North America, the term ermine is used for weasels with white coats. Another synonym for Mustela Erminea is the long-tailed weasel, which refers to the subspecies found in North America. Mustela Erminea is also sometimes called the bridled weasel, due to the distinctive markings on its face.
