What is the name of the white fox with big ears?

White foxes with noticeably large ears are a rare and fascinating type of fox found in certain parts of the world. Their distinctive physical features and elusive nature have made them the subject of much interest and inquiry. In this article, we will explore the identifying characteristics of these unusual foxes, examine their geographic range and habitat, and reveal the accepted common name for this variety in the scientific community.

As members of the dog family Canidae, foxes display a wide diversity in coat color, behavior, and habitat. The most common species, the red fox, has auburn fur and a bushy, white-tipped tail. However, melanistic (black) and leucistic (white) color morphs exist in variable frequencies within fox populations, producing dark or very pale individuals. When white foxes additionally possess abnormally large, wide-set ears, their appearance becomes quite striking and fuels curiosity about their origins and proper classification.

Physical Features

The most instantly noticeable attribute of the white fox is, of course, its snowy white fur. In contrast to the red fox’s tawny pelt, the hairs of the white fox lack the red-brown pigment phaeomelanin. This is caused by a genetic mutation that disrupts normal pigment deposition during hair growth. The resulting pale, frosted coat provides camouflage in snowy northern climates during winter months.

In addition to this leucistic pelage, the other defining feature is the fox’s disproportionately sizable ears. Spanning 5-7 inches in length and width, they dominate the facial profile and resemble satellite dishes swiveling atop the head. Elongated, oversized ears like these are termed “lop ears” and represent an abnormal structural conformation. The amplification of sound granted by the enlarged pinna (outer ear flap) does confer heightened auditory acuity however, improving prey detection and risk avoidance.

Otherwise, white foxes share the general vulpine build – a medium-sized canine with a narrow muzzle, lithe frame, and bushy tail. True to fox kind, they exhibit extraordinary agility, quick reflexes, and keen senses evolved for a predatory lifestyle.

Range and Habitat

The range of the white fox lies primarily in northern regions of Canada, Alaska, Scandinavia, Russia, and throughout the Arctic tundra biome. Their distribution overlaps with the historical reach of the Arctic fox but is more restricted than their common red cousin.

Suitable habitat consists of open grassland plains, alpine meadows, and boreal forests with snow cover through frigid winters. These high latitude regions provide ideal camouflage for their pale pelage while snow is on the ground. Come spring, seasonal molting restores the bright rusty-red undercoat.

Density is always low and scattered. Individuals or mated pairs establish and defend a territory while avoiding overlap with neighboring fox families. Home ranges span 2-10 square miles on average but may be larger in less productive areas.

Diet and Hunting

As opportunistic predators and scavengers, white foxes consume a wide variety of prey. Small rodents like lemmings and voles make up a large portion of their diet. Ptarmigan, hares, ducks, and fish supplement when available. Carrion from larger kills and invertebrates also help these omnivores survive the lean times.

Keen hearing aids in locating subnivian rodents, and pouncing with their front paws helps break through the top layer of snow to grab prey. Cacheing excess food helps sustain them when hunting conditions deteriorate. Adaptability and versatility enable them to exploit locally and seasonally abundant resources.

Reproduction and Lifespan

Breeding occurs in spring shortly after juveniles disperse to establish new territories. Following a 52 day gestation, a litter of 2-12 kits emerges in a prepared den. Both parents provision and protect the altricial young which remain dependent through the summer before dispersing in early fall.

Under natural conditions, average lifespan is 3-5 years with high juvenile mortality. In the absence of severe weather fluctuations, food shortages, and diseases, they may reach up to 10 years in captivity.

Relation to Arctic Fox

The similar geographic range and ecological niche occupied by white and Arctic foxes understandably leads to comparisons between the two. However, they constitute distinct species with several differentiating characteristics:

Trait White Fox Arctic Fox
Size Medium – 7-15 lbs Small – 3-4 lbs
Ears Disproportionately large Smaller, proportionate ears
Winter Coat Mostly white with rusty underfur Pure white year-round
Cold Tolerance Moderate – avoids extreme cold Highly adapted to cold extremes
Diet More varied as omnivore Heavily carnivorous
Habitat Breadth Less specialized, more flexible Narrowly adapted to tundra

The white fox thereby occupies a distinct niche separate from the smaller and more hypercarnivorous Arctic fox. Hybridization may occasionally occur where their ranges abut but does not blend away their genomic and functional uniqueness.

Taxonomic Classification

Since its initial discovery by European explorers in the 1700s, the scientific community has wrestled with the proper taxonomic designation for the white fox. Various authorities have labeled it as a color phase of the red fox, the Arctic fox, or the kit fox in the intervening centuries.

Modern genetic analysis confirms its status as a clearly delineated species belonging to the Vulpini tribe of true foxes. Most taxonomists currently assign it to the genus Vulpes as:

Vulpes lagopus

The species name lagopus derives from Ancient Greek meaning “rabbit foot”, referencing its furry paws for traction over snow. This binomial Latin name reflects its close ancestry with but distinction from other foxes in the Vulpes genus.

Other Common Names

Beyond the formal Linnaean nomenclature, the white fox also answers to a diversity of informal common names reflecting the many indigenous populations that overlap with its range. Some frequently used ones include:

– Polar fox
– Snow fox
– White-eared fox
– Northern fox
– Alaskan fox
– Arctic blue fox

But the most widely used and recognized vernacular name, especially in North America, is:

White-tailed jackalope

This colorful moniker references the fox’s bright white coat and tail along with its oversized “jackalope-like” ears. The origins of this name are steeped in myth and legend as early trappers and explorers returned with improbable tales of this strange northern creature. The jackalope association stimulates the imagination but also aptly captures the essence of this unique fox.

So in summary, while known by an assortment of regional nicknames, the accepted scientific name Vulpes lagopus and common name white-tailed jackalope identify this elusive, lop-eared canid of the Far North.


The mysterious white fox with floppy ears has sparked fascination and speculation for centuries within indigenous cultures and the scientific community alike. We now have a firm understanding of its relationship to other fox species, as neither an Arctic fox variant nor entirely new species but rather occupying its own distinct niche as Vulpes lagopus – the white-tailed jackalope.

Its blend of adaptive traits allows it to thrive amid the challenging conditions of the Arctic and subarctic spheres. As with many wildlife specialists inhabiting Earth’s extreme environments, the white jackalope requires continued thoughtful stewardship recognizing its integral place in these delicate ecosystems. Complete elucidation of its secrets remains an ongoing endeavor sure to reveal fresh surprises for generations to come.
