mustelid comparison stoat weasel 2sq

Weasel (right) and stoat (left) - dorsal (back) view.

Weasels and stoats are often confused but the difference between the tails is a distinguishing feature:

  • weasels have a proportionately shorter tail (barely longer than the hind legs) compared to stoats (noticeablly longer than the hind legs)
  • weasels do not have a black tip on their tails, but stoats do.
