Lesser mole-rat

The lesser mole-rat (Spalax leucodon) is a species of rodent in the family Spalacidae found in Albania, Bosnia and Herzegovina, Bulgaria, Greece, Hungary, North Macedonia, Romania, Serbia, Montenegro, Israel, Turkey, Iran and Ukraine. There have been suggestions that its taxonomic position should change in the light of new scientific information. Modern authors tend to separate this and some closely related mole rat species from other Spalax species by classifying them into a separate genus named Nannospalax. A cariological study showed that Nannospalax leucodon is a superspecies consisting of several cariologically distinct cryptic species. According to this definition there are four separate cariological forms in the Carpathian Basin, one of them endangered and another one vulnerable while insufficient data are available to evaluate the conservation status of the other two forms. One study directed towards life expectancy, used this species by virtue of its incredible longevity performance, hypoxia and hypercapnia endurance, as well as cancer resistance.[1] Looking at the fecal and skin samples of this ideal candidate, it was found that the Muribaculaceae bacterial family, known to be linked with longevity, was dominating in fecal samples.
