Family Tree

Weasels, stoats, polecats, martens, minks, otters and badgers are all members of the weasel family (Mustelidae), and resemble each other in build, colouring or behaviour. Mustelidae is one of the oldest families of mammals, as well as one of the largest families of carnivores. The difference in size between the smallest and largest mustelid species is noticeable. Mustelids have elongated bodies, short legs and scent glands.
