What is the maximal age a Silvery mole-rat reaches?
An adult Silvery mole-rat (Heliophobius argenteocinereus) usually gets as old as 3.08 years.
Silvery mole-rats are around 87 days in the womb of their mother. When born, they weight 7 grams (0.02 lbs) and measure 3.4 cm (0′ 2″). As a member of the Bathyergidae family (genus: Heliophobius), a Silvery mole-rat caries out around 2 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 15.5 cm (0′ 7″).
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 silvery mole-rat, silvery blesmol, or silky mole-rat (Heliophobius argenteocinereus) is a species of mole-rat of East Africa which occurs in southern Kenya, Tanzania, southeastern Democratic Republic of Congo, Mozambique and Malawi. Solitary and aggressive, little is known about its ecology or behavior. It is monotypic in the genus Heliophobius. A common species, the International Union for Conservation of Nature has rated it as being of “least concern”.
