The Arctic fox lives in dens under the snow in the Arctic regions of the Northern Hemisphere, including Europe. They eat small animals like hares and seal pups and try to survive predators like polar bears, wolves, humans, and snowy owls. Arctic foxes have fur that can be white, black, gray, or mixed and a body adapted to leaping and smelling prey and predators. The author wrote about Arctic foxes because they are special to them and they want others to learn more about these animals.
