AnAge entry for Nannospalax ehrenbergi

Classification (HAGRID: 03351)
Taxonomy	Kingdom: Animalia Phylum: Chordata Class: Mammalia (Taxon entry) Order: Rodentia Family: Muridae Genus: Nannospalax
Species	Nannospalax ehrenbergi
Common name	Palestine mole rat
Lifespan, ageing, and relevant traits
Maximum longevity	15 years (captivity)
Source	ref. 671
Sample size	small
Data quality	acceptable
Observations	These animals live on average about 3 years in the wild but can live more than 15 years in captivity. They become sexually mature in their second year of life, though they are difficult to breed in captivity [0675]. Captive animals only show signs of ageing after they are 10 years or older (Eviatar Nevo, pers. comm.). One wild born specimen was at least 15 years old and still living in captivity [0671]. Some authors place this species in the Spalacidae family.
