mustelid comparison stoat weasel 1sq

Weasel (right) and stoat (left) - ventral (belly) view.

Weasels and stoats are often confused but distinguishing features include:

  • the line between brown and white fur along the underside is patchy / wavy on weasels and straighter on stoats
  • weasels have a shorter tail, barely longer than their hind legs, compared to stoats
  • weasels do not have a black tip on their tails, but stoats do.
