How old does a Naked mole-rat get? (age expectancy)

What is the maximal age a Naked mole-rat reaches?

An adult Naked mole-rat (Heterocephalus glaber) usually gets as old as 10 years.

Naked mole-rats are around 70 days in the womb of their mother. When born, they weight 1 grams (0 lbs) and measure 1.3 cm (0′ 1″). As a member of the Bathyergidae family (genus: Heterocephalus), a Naked mole-rat caries out around 11 little ones per pregnancy, which happens around 4 times a year. Fully grown, they reach a bodylength of 13 cm (0′ 6″).

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.

A Naked mole-rat gets as old as 10 years

The naked mole-rat (Heterocephalus glaber), also known as the sand puppy, is a burrowing rodent native to parts of East Africa. It is closely related to the blesmols and is the only species in the genus Heterocephalus of the family Heterocephalidae. The naked mole-rat and the Damaraland mole-rat (Fukomys damarensis) are the only known eusocial mammals, the highest classification of sociality. It has a highly unusual set of physical traits that allow it to thrive in a harsh underground environment and is the only mammalian thermoconformer, almost entirely ectothermic (cold-blooded) in how it regulates body temperature.The naked mole-rat lacks pain sensitivity in its skin, and has very low metabolic and respiratory rates. While formerly considered to belong to the same family as other African mole-rats, Bathyergidae, more recent investigation places it in a separate family, Heterocephalidae. The naked mole-rat is also remarkable for its longevity and its resistance to cancer and oxygen deprivation.
