So you want to know more...
- The Arctic fox is able to walk on top of
snow and listen for the movement of prey beneath it.
- The Arctic fox is the best-traveled of any
terrestrial mammal with the exception of Homo sapiens (Nowak,
1999).
- Captive breeding of the fox has revealed
that the blue morph, while uncommon in the wild (constituting less
than 5 percent of some populations), is actually the dominant form (Sale,
2006).
- Overtrapping drove the fox nearly to
extinction in many areas, yet today the fox's status is "not
threatened."
- The winter coat develops in October and is
shed in April.
- Although the white morph fox is typically a
very pure white during the winter, in areas with a slightly warmer
climate they may remain relatively dark throughout the whole year,
more closely resembling the color of their summer coat (Nowak,
1999).
- The
Arctic fox's vocalizations include barks, screams, and hisses, yet
are seldom heard except during breeding season, during territorial
disputes, and to warn their young.
