European polecat

The European polecat (Mustela putorius) — also known as the black or forest polecat, or fitch (as well as some other names) — is a species of mustelid native to western Eurasia and North Africa. It is of a generally dark brown colour, with a pale underbelly and a dark mask across the face. Occasionally, colour mutations, including albinos and erythrists, occur. Compared to minks and other weasels — also fellow members of the genus Mustela — the polecat has a shorter, more compact body; a more powerfully built skull and dentition; is less agile; and it is well known for having the characteristic ability to secrete a particularly foul-smelling liquid to mark its territory.
