How old does a Spinifex hopping mouse get? (age expectancy)

What is the maximal age a Spinifex hopping mouse reaches?

An adult Spinifex hopping mouse (Notomys alexis) usually gets as old as 5.17 years.

Spinifex hopping mouses are around 32 days in the womb of their mother. When born, they weight 2 grams (0 lbs) and measure 3.5 cm (0′ 2″). As a member of the Muridae family (genus: Notomys), their offspring is 4 babies per pregnancy. Fully grown, they reach a bodylength of 10 cm (0′ 4″).

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 spinifex hopping mouse (Notomys alexis), also known as the tarkawara or tarrkawarra, occurs throughout the central and western Australian arid zones, occupying both spinifex-covered sand flats and stabilised sand dunes, and loamy mulga and melaleuca flats.The population fluctuates greatly: in normal years it is sparsely distributed and probably confined to sandy country; after rain the population explodes and spreads to other types of habitat for a time. They are mostly seen at night, bounding across open ground on their large hind feet, with tails extended and the body almost horizontal. As semi-fossorial, burrowing surface foragers, the tiny hopping mice spend a great deal of energy not just foraging for food, but also transporting it back to their burrows. In fact, it was found that the total energy spent on transporting food in relation to energy investment on burrows far outweighed any other similar type of species (White, 2006).
