北极狼

Arctic wolves are larger and stockier than other species of wolves to enable them to withstand the harsh conditions in which they live.

All arctic wolf pups are born with blue eyes, which turn orange or yellow between 4 to 8 weeks old, although very occasionally a wolf may retain their blue eyes to adulthood.

Arctic wolves have had little exposure to humans and thus are not scared of people; they are likely to approach humans with curiosity.

Arctic wolves can withstand temperatures as low as -53C.

The population of Arctic wolves fluctuates depending on the success of the breeding season of their prey.
