Weasel Worker Course Crew

Weasels are mammals of the genus ''Mustela'' of the family Mustelidae. The genus ''Mustela'' includes the least weasels, polecats, stoats, ferrets and European mink. Members of this genus are small, active predators, with long and slender bodies and short legs. The family Mustelidae, or mustelids (which also includes badgers, otters, and wolverines), is often referred to as the "weasel family". In the UK, the term "weasel" usually refers to the smallest species, the least weasel (''M. nivalis''), the smallest carnivoran species.

Least weasels vary in length from , females being smaller than the males, and usually have red or brown upper coats and white bellies; some populations of some species moult to a wholly white coat in winter. They have long, slender bodies, which enable them to follow their prey into burrows. Their tails may be from long.

Weasels feed on small mammals and have from time to time been considered vermin because some species took poultry from farms or rabbits from commercial warrens. They do, on the other hand, eat large numbers of rodents. Their range spans Europe, North America, much of Asia and South America, and small areas in North Africa.

Terminology

The English word "weasel" was originally applied to one species of the genus, the European form of the least weasel (''Mustela nivalis''). This usage is retained in British English, where the name is also extended to cover several other small species of the genus. However, in technical discourse and in American usage, the term "weasel" can refer to any member of the genus, or to the genus as a whole. Of the 16 extant species currently classified in the genus ''Mustela'', 10 have "weasel" in their common names. Among those that do not are the three species of ermine, the polecats, the ferret, and the European mink.

The American mink and the extinct sea mink were commonly included in this genus as ''Mustela vison'' and ''Mustela macrodon'', respectively, but in 1999 they were moved to the genus ''Neovison''. In 2021, both ''Neovison'' species, along with the long-tailed weasel (''Mustela frenata''), Amazon weasel (''Mustela africana'') and Colombian weasel (''Mustela felipei'') were moved to the genus '' Neogale'', as the clade containing these 5 species was found to be fully distinct from ''Mustela''.

Cultural meanings

Weasels have been assigned a variety of cultural meanings.

In Greek culture, a weasel near one's house is a sign of bad luck, even evil, "especially if there is in the household a girl about to be married", since the animal (based on its Greek etymology) was thought to be an unhappy bride who was transformed into a weasel and consequently delights in destroying wedding dresses. In Macedonia, however, weasels are generally seen as an omen of good fortune.

In early-modern Mecklenburg, Germany, amulets from weasels were deemed to have strong magic; the period between 15 August and 8 September was specifically designated for the killing of weasels.

In Montagne Noire (France), Ruthenia, and the early medieval culture of the Wends, weasels were not meant to be killed.

According to Daniel Defoe also, meeting a weasel is a bad omen. In English-speaking areas, weasel can be an insult, noun or verb, for someone regarded as sneaky, conniving or untrustworthy. Similarly, " weasel words" is a critical term for words or phrasing that are vague, misleading or equivocal.

Japanese superstitions

In Japan, were seen as '' yōkai'' (causing strange occurrences). According to the encyclopedia ''Wakan Sansai Zue'' from the Edo period, a pack of weasels would cause conflagrations, and the cry of a weasel was considered a harbinger of misfortune. In the Niigata Prefecture, the sound of a pack of weasels making a rustle resembled six people hulling rice, so was called the "weasel's six-person mortar", and it was an omen for one's home to decline or flourish. It is said that when people chase after this sound, the sound stops.村上健司編著 『妖怪事典』 毎日新聞社、2000年、36頁。。

They are also said to shapeshift like the fox ('' kitsune'') or ''tanuki'', and the ''nyūdō-bōzu'' told about in legends in the Tōhoku region and the Chūbu region are considered weasels in disguise, and they are also said to shapeshift into '' ōnyūdō'' and little monks.

In the collection of depictions, the '' Gazu Hyakki Yagyō'' by Sekien Toriyama, they were depicted under the title 鼬, but they were read not as "''itachi''", but rather as " ''ten''", and "ten" were considered to be weasels that have reached one hundred years of age and became yōkai that possessed supernatural powers. Another theory is that when weasels reach several hundred years of age, they become ''mujina'' ( Japanese badgers).

In Japanese weasels are called and in the Tōhoku Region and Shinshu, it was believed that there were families that were able to use a certain practice to freely use ''kudagitsune'' as ''iizuna-tsukai'' or ''kitsune-mochi''. It is said that Mount Iizuna, from the Nagano Prefecture, got its name due to how the gods gave people mastery of this technique from there.『広辞苑 第4版』(1991年)、岩波書店「いづなつかい【飯綱使・飯縄遣】」の項

According to the folkloristician Mutō Tetsujō, "They are called ''izuna'' in the Senboku District, Akita Prefecture, and there are also the ichiko (itako) that use them."。 Also, in the Kitaakita District, they are called'' mōsuke'' (猛助), and they are feared as ''yōkai'' even more than foxes ('' kitsune'').

In the Ainu language, ermines are called ''upas-čironnup'' or ''sáčiri'', but since least weasels are also called ''sáčiri'', Mashio Chiri surmised that the honorary title ''poy-sáčiri-kamuy'' (where ''poy'' means "small") refers to least weasels.

''Kamaitachi''

'' Kamaitachi'' is a phenomenon wherein one who is idle is suddenly injured as if his or her skin were cut by a scythe. In the past, this was thought to be "the deed of an invisible ''yōkai'' weasel". An alternate theory, asserts that ''kamaitachi'' is derived from , so were not originally related to weasels at all.
