What are the arctic wolf's unusual or interesting characteristics?

The Arctic wolf has several interesting characteristics, including its thick, white fur that provides insulation against extreme cold and helps it blend into its snowy environment. Unlike many other wolf species, Arctic wolves can survive in temperatures as low as -40°F (-40°C) due to their specialized physiology and adaptations. They also have a unique social structure, often living in smaller packs or even solitary, which allows them to effectively hunt in the harsh Arctic terrain. Additionally, Arctic wolves have a keen sense of smell, enabling them to locate prey buried under snow.
