*The Corsac fox is the only fox with round pupils
*They avoid areas where snow height measures 150mm or over.
*They make their home in dens made by marmots and ground squirrels.
* They have fur on the underside of their paws.There are 21 species of fox living across the World. Australasia, Madagascar and the Antarctic are the only places that do not have a native species.
They are widespread across many habitats from the Arctic tundra, to deserts and city centres.The red fox is the most familiar to us as it is common in Britain, but most species are much smaller and the Corsac fox is typical of this.
The Corsac fox is one of the modern vulpes species and their closest relatives are the Swift fox and Arctic fox however they can also claim the oldest fossil record of any member of the modern vulpes family; the Praecorsac.
Corsac foxes live in the dry-steppes, semi-deserts and deserts from the lower Volga river and Iran to Mongolia, Manchuria and Tibet. Their habits are virtually unknown.
In adaptation to where they live the corsac fox needs little water to survive getting most moisture from their food.
Their diet consists of mainly insects and small rodents such as mice, voles, gerbils and pika. Our foxes however eat salmon, turkey, chicken, clams, eggs, green beans and kibble.
They have very different coats in the summer and winter as an adaptation to the cold climate in their range. The long fluffy winter coat of blonde and white is much thicker then the short summer coat of red brown and orange.
A similar but more exaggerated seasonal change in colour is also shown by the Arctic fox.
More social then many foxes, the Corsac fox often lives in a large 'leash'/ 'skulk' or as most people know it, group. It is also more diurnal and lacks the characteristic pungent odour associated with many wild canids such as the Red fox, Maned Wolf or Arctic fox.
It is said that in the 17th century they were popular pets in the former USSR.
The biggest decline in the species was in Turkmenistan from 1924 to 1989 when 103,500 corsac pelts were taken.
