Facts about Arctic Fox Fur Coloration
- 05
Both white and blue morph arctic foxes are born with dark fur that lightens as they mature toward their adult coloration.
- 04
During winter, arctic fox fur coloration achieves its white appearance partly because the hollow, air-filled structure of each hair shaft enhances insulation alongside its camouflage function.
- 03
Pigmentation in arctic fox fur coloration is controlled by genetics, with melanin levels determining whether an individual expresses the white or blue morph.
- 02
A rare coastal population of arctic foxes displays a blue-gray coloration year-round, known as the 'blue' morph, rather than turning white in winter.
- 01
The arctic fox undergoes a seasonal molt, transitioning from thick white winter fur to a thinner brown or gray coat in summer for camouflage.
