Facts About Weasel

Weasels are highly active predators of the Mustelidae family and are found in most parts of the world, with the exception of Antarctica, Australia and the neighboring islands. The term is used to collectively classify 10 of the existing 16 species categorized under the genus Mustela. Even stoat, polecats or ferrets belong to the same genus, but they are regarded as separate species. Broadly, weasels are divided into two species, namely the short-tailed weasel or Mustela ermine and the least weasel or Mustela rixosa. Weasels have a long, slender and sinuous body and are quite powerful for their size. A single weasel is capable of running around 274 m, while carrying a large mouse in its mouth. Besides, the animal is regarded as a fearless hunter and can easily confront animals much bigger than its own size. When threatened, weasels are known to attack humans as well, particularly when the latter come between them and their food.
