The arctic fox (Vulpes lagopus) shares the reputation of all foxes for
being cunning. It will follow the polar bear's tracks in the snow in the
hopes of scavenging from a seal carcass in this tough habitat with little
available prey. If that doesn't work, it will turn to its sharp vision and
scent to look for smaller creatures, eggs, or berries. On rare occasions,
it will locate a pup seal that has just been born and dig down to its den.
The arctic fox can sleep safely in the snow for around an hour at
temperatures as low as -50 degrees Celsius thanks to its thick fur, which
traps air and offers great insulation. Even the undersides of its paws are
covered in fur, and the arctic fox uses its furry paws to dig a den
several feet deep in the snow when fierce winds rage across the desolate
landscape.
