What does a common weasel look like?

The common weasel, also known as Mustela nivalis, has a slender body and a long neck, measuring about 7 to 10 inches in length, excluding its tail. Its fur is typically brown or reddish-brown on the back, with a creamy white underbelly. In winter, some populations may exhibit a white coat for camouflage in snowy environments. They have small, rounded ears and bright, dark eyes, giving them a distinctive appearance.
