|North American Long-tailed Weasel|
A weasel is a meat-eating mammal. It is a part of the genus Mustela. At one time only one of the sixteen species of Mustela was called "weasel". This was the European Least Weasel (Mustela nivalis). Today, the term weasel is often used for all species of the group. Ten of the sixteen species have the word "weasel" in their common name. Those that are not called weasel include the stoat, the two species of mink, and the polecats or ferrets. A group of weasels is called a pack, gang, confusion, or boogle.
Weasels length is from 12 to 45 centimetres (5 to 18 in), and usually have a red or brown upper coat and a white belly.They have long slender bodies, which enable them to follow their prey into burrows. Their tails may be from 22 to 33 centimetres (9 to 13 in) long. Weasels are famous for their cleverness and guile.
