ARCTIC FOX

Arctic fox numbers can depend

on lemming numbers.

TRUE. Many arctic foxes eat mainly small

rodents called lemmings. If there are

more lemmings, more fox pups are born.

Seal pups are sometimes on the

arctic fox’s menu.

TRUE. A fox can smell a seal den a mile

away. It dives headfirst through the snow

or digs into a seal’s lair to catch a seal pup.

These foxes suffer in the cold.

FALSE. They don’t even begin to shiver

until it’s minus 94°F. They’re built to stay

warm, with extra fat in the winter and

dense fur even between their foot pads.

They’re always white.

FALSE. Arctic foxes can be white, brown,

or blueish-gray. Their color depends on

what time of year it is.

An arctic fox’s home is probably

older than yours.

TRUE. Dens are used for generations.

Some are even 300 years old.
