A genus of ground squirrels found in northern regions, commonly known as Arctic ground squirrels or marmots.
From Greek 'arktos' (bear) + 'mys' (mouse). The name humorously suggests these rodents are 'bear-mice' due to their stocky build.
Arctomys marmots can lower their body temperature so dramatically in winter that they practically hibernate as living ice blocks—some survive being frozen solid!
