What is the maximal age a Gray fox reaches?
An adult Gray fox (Urocyon cinereoargenteus) usually gets as old as 15 years.
Gray foxs are around 61 days in the womb of their mother. When born, they weight 104 grams (0.23 lbs) and measure 8.4 cm (0′ 4″). As a member of the Canidae family (genus: Urocyon), their offspring is 3 babies per pregnancy. Fully grown, they reach a bodylength of 60.3 cm (2′ 0″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The gray fox (Urocyon cinereoargenteus), or grey fox, is an omnivorous mammal of the family Canidae, widespread throughout North America and Central America. This species and its only congener, the diminutive island fox (Urocyon littoralis) of the California Channel Islands, are the only living members of the genus Urocyon, which is considered to be the most basal of the living canids. Though it was once the most common fox in the eastern United States, and still is found there, human advancement and deforestation allowed the red fox to become more dominant. The Pacific States still have the gray fox as a dominant. It is the only American canid that can climb trees. Its specific epithet cinereoargenteus means “ashen silver”.
