Common raccoon dog
Nyctereutes procyonoides

— Where the name comes from
Nyctereutes is Greek and means “night hunter”, from nýx, “night”, and ereutḗs, “one who searches”. Procyonoides means “raccoon-like”, for the dark mask over the eyes: a canid bearing the name of an American carnivore it is not related to. In Japan it is the tanuki, a folklore figure able to shape-shift, and its terracotta statues stand outside houses to bring luck.

— What sets it apart
It did not reach Europe by itself: between the 1920s and the 1950s the Soviet Union released over nine thousand animals in the European part of the country, to create a fur resource to be hunted in the wild. The operation succeeded all too well — the animal has spread west across half a continent, and is now on the European list of invasive species of Union concern. It is the rare case in which the year, the number and the exact motive of a biological invasion are known: it is all in the archives.
