Like all other wolves, white wolves are predators in packs, usually 5 to 10. Most of them prey on reindeer and musk oxen, but they also kill arctic rabbits, lemmings, moose, fish, walrus and other animals, and sometimes even attack humans.
In winter, they also hunt red deer, because in winter, red deer's long legs will fall into thick snow, which gives Arctic wolves a good opportunity to easily kill one of the largest land animals in the world.
