The official start of winter is only a few days away. But for some animals, surviving the cold is a year-round effort. Whether on land or at sea, these three Arctic animals show us how to do the cold right.
Walrus
They may look all tooth-and-blubber, but there is more to a walrus than meets the eye. For example, did you know that they can control their heart beat to help withstand the cold? Or that male walruses are quite the singers? During courtship, some males sing for up to 65 hours! But perhaps what is most remarkable about walruses is their intelligence. They share food, help defend each other, display social mimicry, and have strong social bonds (a female walrus will stay with its mother for life).
