Snow Monkeys (Japanese Macaque) ( $120 )

7) The “snow monkey” or Japanese macaque (Macaca fuscata) is famous for its habit of sitting in hot springs in the high, snow-covered Japanese Alps of Honshu (the main island). This behaviour evolved quite recently, after one particular monkey living near the village of Jikogudani observed humans enjoying a hot soak in the outdoor hot bath of a local guesthouse, and jumped in with them. Finding it most enjoyable, the behaviour has since been learnt by others in the troop, and the local community (of people) have since built the monkeys their own onsen.
