Arctic Fox
The arctic fox survives cold temperatures as low as –58°F in the Arctic. Their staple food is lemmings but they are not too picky and will eat whatever is available. This video shows how the arctic fox jumps up and dives head first into the snow looking for lemmings. Looks painful but it does break the layer of snow below to expose the animals below, like the lemming.:)
