The naked mole-rat (Heterocephalus glaber), also known as the sand puppy, [6] is a burrowing rodent native to the Horn of Africa and parts of Kenya, notably in Somali regions. [1] It is closely related to the blesmols and is the only species in the genus Heterocephalus .

The Middle East blind mole-rat weighs 100–200 grams (3.5–7.1 oz). It has light gray fur and four sharp teeth, two large teeth in the upper jaw and two smaller teeth in the lower jaw. It has a life span of up to 20 years and is notable for its adaptability to severe lack of oxygen. In Israel, the blind mole-rat is a major agricultural pest.

The naked mole-rat has a particularly long life-span for a small rodent, about 30 years, and the basis for this longevity has been investigated. [46] Naked mole-rats express DNA repair genes, including core genes in several DNA repair pathways, at a higher level than shorter-lived mice, and thus it was suggested that DNA repair acts as a ...
Aging and longevity researchers utilize LQ with additional metrics such as maximum species life span (MLSP). Rochelle Buffenstein considers MLSP as an important species aging characteristic that can vary over a factor of 40,000 throughout the animal kingdom, and is related species increase in body size.

In 2018, naked mole-rats were identified as the first mammal to defy the Gompertz–Makeham law of mortality, and achieve negligible senescence. It has been speculated, however, that this may be simply a "time-stretching" effect primarily due to their very slow (and cold-blooded and hypoxic) metabolism. [6] [7] [8]
