Snow monkeys in the mountain

Those Japanese macaques should have suffered long ago from the violent assaults of the harsh winters from Hokkaido; They should have disappeared from these regions hostile to the small cercopithécidae (or “old world monkeys“). And still, they adapted. Specifically, they learned to warm themselves in the spa waters of always-warm springs created by the intense local geothermal activity.
