Arctic animals have various adaptations to survive extreme cold. Polar bears possess thick blubber and two layers of fur for insulation and an elongated snout to warm air [1][6]. Arctic foxes and hares have thick fur, smaller limbs, and small ears to reduce heat loss [3][4]. Reindeer have antlers for digging through snow and special vision for spotting food [3]. Walruses use tusks to haul onto ice and echolocation for navigation [1]. These adaptations are essential for thriving in harsh Arctic conditions.
