As one of Canada’s most beautiful mammals, the Arctic fox is well-known for its white fur which is why it’s often referred to as the snow fox.

Arctic foxes are great architects: to nurse her whelps (baby Arctic foxes), a female Arctic fox digs burrows that can go 1.8 to 3.6 metres underground, with as many as 100 entrances. That’s a lot of digging!
The Arctic fox is the smallest member of the canid family in Canada. Despite being in the same family as large wolves, the Arctic fox measures only 75 to 115 centimetres long. Even then, one-third of its length comes from its bushy tail. This fox is about the same size as a big house cat or a small dog, but don’t be fooled – it is not a pet!
Arctic foxes can change the colour of their coats depending on the season, and they are the only member of the canid family that can do so. During summer, their coat is brown or grey with a light-coloured belly. During winter, an Arctic fox’s fur turns thick and white. This change gives them camouflage throughout the year, making it harder for their prey to spot them while they’re on the hunt.
Their fur also helps them stay nice and warm; the Arctic fox has the warmest fur coat of any animal found in the Arctic and can endure temperatures as low as -50 C. Their other characteristics, such as short legs, short muzzles and small rounded ears, help them battle the cold by reducing the amount of body surface area exposed to heat loss. Less body = less cold!
The Arctic fox is both a hunter and a scavenger. To find prey during the winter, it uses its strong senses of hearing and smell to detect small animals that are active underneath the snow. Its prey consists of rodents, birds and fish – it will even eat vegetables if they are available! Arctic fox parents have a lot of mouths to feed: the average litter size is 14 whelps – the largest recorded litter of any wild mammal in the world!
In Canada, the Arctic fox is found in the northern boreal region up to the Arctic, from James Bay to the top of Ellesmere Island. Around the world, Arctic foxes live in the circumpolar Arctic, including Greenland (Denmark), Iceland, Finland, Sweden, Norway and Russia.
Each Arctic fox has its own home range, extending up to 25 square kilometres. They are very mobile and can travel large distances over both land and sea ice.

An estimated annual $175-billion business, the illegal trade in wildlife is the world’s fourth-largest criminal enterprise. It stands to radically alter the animal kingdom.

This past summer an ambitious wildlife under/overpass system broke ground in B.C. on a deadly stretch of highway just west of the Alberta border. Here’s how it happened.
