Canis lupus arctos, commonly known as the Arctic wolf, is a subspecies of the gray wolf found primarily in the Arctic regions of North America and Greenland. These wolves are well-adapted to their cold environments, featuring a thick, white coat that provides insulation and camouflage in snowy landscapes. They typically live in packs and hunt caribou, muskoxen, and other prey. Arctic wolves have a smaller body size compared to other gray wolves, which helps them conserve heat. Their social structure is crucial for survival, as they work together to hunt and protect their territory. This subspecies plays an important role in maintaining the balance of its ecosystem.
