query: What is the color of the Arctic Fox's fur?
passage: Arctic fox
[7]The Arctic fox (Vulpes lagopus), are also known as the white fox, polar fox, or snow fox, that is a small fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome.[1][8] It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage. On average, Arctic foxes only live 3–4 years in the wild.[9] Its body length ranges from 46 to 68cm (18 to 27in), with a generally rounded body shape to minimize the escape of body heat.
passage: Ethiopian wolf
The Ethiopian wolf has short guard hairs and thick underfur, which provides protection at temperatures as low as −15 °C. Its overall colour is ochre to rusty red, with dense whitish to pale ginger underfur. The fur of the throat, chest and underparts is white, with a distinct white band occurring around the sides of the neck. There is a sharp boundary between the red coat and white marks. The ears are thickly furred on the edges, though naked on the inside. The naked borders of the lips, the gums and palate are black. The lips, a small spot on the cheeks and an ascending crescent below the eyes are white. The thickly furred tail is white underneath, and has a black tip, though, unlike most other canids, there is no dark patch marking the supracaudal gland. It moults during the wet season (August–October), and there is no evident seasonal variation in coat colour, though the contrast between the red coat and white markings increases with age and social rank. Females tend to have paler coats than males. During the breeding season, the female's coat turns yellow, becomes woolier, and the tail turns brownish, losing much of its hair.
