The Arctic Fox, also known as the Snow Fox, Polar Fox or its latin name Alopex lagopus, is a small omnivore, it eats both plants and animals. It can be found throughout the Arctic tundra, in Alaska, Canada, Greenland, Russia, Norway, Scandinavia, and even Iceland. The Arctic Foxes as a species are close to being endangered from global warming, see 7.0 for more details.

The Arctic Fox’s diet consists mostly of lemmings and voles, small rodents that live under the snow, but they have also been know to eat berries, bird eggs and scavenge from the kills of larger predators such as Polar Bear

The population size of Arctic Foxes depends on the amount of food available to them, therefore the Arctic Fox population generally depends on the amount of their staple food source, lemmings.

Arctic Foxes have greatly adapted their behaviour to fit into the arctic environment, something interesting about Arctic Foxes is how they hunt; they have excellent hearing so they can locate lemmings and voles burrowing under the snow. Once they have found their prey, they leap into the air, and pounce right through the snow layer, and onto the rodent. In the winter, if food is scarce, Arctic Foxes will follow polar bears out onto the ice and scavenge what is left of their kills.
