Detailed explanation-1: -White fur not only provides camouflage in winter but adds warmth. A pigment called melanin, absent in white fur, gives the fox its brown summer coat.
Detailed explanation-2: -When the snow starts to melt, the fox sheds its winter coat for a thinner greyish-brown coat. Near the end of summer the Arctic fox begins to grow a thicker coat again. The color of the fur turns grey and then white. The oily fur sheds water and helps to keep the fox dry.
Detailed explanation-3: -In the winter, these foxes boast a long white coat that sheds to short, dark gray to bluish-brown fur in the summer. They measure three feet from nose to tail and weigh between six and 12 pounds.
Detailed explanation-4: -As temperatures warm and summer approaches, animals molt, shedding their winter-white coats for earthier hues. With new shades of brown, gray, black, and red, their coats reflect the change in seasons and new ground cover and vegetation.
Detailed explanation-5: -Did you know the Arctic fox’s coat changes with the season? In winter, their fur is all white, which then turns to gray-brown in the summer. This provides very effective camouflage. See if you can spot the Arctic foxes at Polar Frontier!
