Arctic foxes are an omnivorous predator. It preys on lemmings and other rodents, sealing cubs, fish, birds, eggs, insects and other invertebrates. It also eats berries, seaweed and carrion, sometimes tracking polar bears to eat their wreckage. Arctic foxes bury excess food in the cache to store winter and feeding kits. Arctic foxes are preyed by red foxes, hawks, wolves, wolves and bears. The IUCN classifies the protection status of Arctic foxes as “the least concerned.” It is estimated that the number of global arctic foxes reaches hundreds of thousands. However, the species is rapidly extinct in Northern Europe, with fewer than 200 adults in Norway, Sweden and Finland. Although hunting has been banned for decades, animals have been poached for their precious fur. The population of the Russian island of Medici is also on the verge of extinction. Arctic foxes face serious challenges from hunting and climate change. The warm temperatures make the fox’s white winter color easy to see by predators. In particular, the red fox threatens the Arctic fox. In some areas, the red fox has become dominant, and its predator, the grey wolf, has been hunted to near extinction. Disease and prey scarcity affect Arctic fox populations in certain parts of their range.
