A lot of things could kill you in 19th Century Finland but perhaps one of the nastiest ways to go was to be attacked by a wolf. The grey wolf (canis lupus) is most active by night and usually hunts in packs to predate on ungulates like deer and moose. Wolves can also hunt in pairs or alone. Wolves have exceptional endurance and can travel far and fast.
Wolves by their nature avoid people and, according to one study, there have been fewer than 3,000 people killed by wolves worldwide in the past 300 years.
