What is the maximal age a White-tailed jackrabbit reaches?
An adult White-tailed jackrabbit (Lepus townsendii) usually gets as old as 8 years.
White-tailed jackrabbits are around 40 days in the womb of their mother. When born, they weight 90 grams (0.2 lbs) and measure 14 cm (0′ 6″). As a member of the Leporidae family (genus: Lepus), a White-tailed jackrabbit caries out around 4 little ones per pregnancy, which happens around 3 times a year. Fully grown, they reach a bodylength of 51.3 cm (1′ 9″).
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 white-tailed jackrabbit (Lepus townsendii), also known as the prairie hare and the white jack, is a species of hare found in western North America. Like all hares and rabbits, it is a member of the family Leporidae of order Lagomorpha. It is a solitary individual except where several males court a female in the breeding season. Litters of four to five young are born in a form, a shallow depression in the ground, hidden among vegetation. This jackrabbit has two described subspecies: L. townsendii townsendii occurring west of the Rocky Mountains and L. townsendii campanius occurring east of the Rocky Mountains.
