Weasel comes from the genus Mustela of the Mustelidae family. A small, active predators, with long and slender body plus short legs. Some species of weasel do molting in winter and covered in white fur.
The least weasel or Mustela nivalis is the smallest member of the Mustelidae and the cutest for me. Also there are stoat or ermine that's so similar with least weasel, but can be distinguished from it's larger size and prominent black tip of it's tail. Well I never think that it would be like that.
Yes, it's a predator and it can kill rabbit also that's bigger. T_T What a cruel little kid. Weasel is clever and can move so quickly with their body. They can follow their prey into the burrows fast. Weasel now considered as vermin cause of some cases where they took their prey form farms.
Oh, do you know? In some cultural meanings, weasel means bad lucks.
