The Middle East blind mole-rat or Palestine mole-rat (Spalax ehrenbergi) (also known as Nannospalax ehrenbergi) is a species of rodent in the family Spalacidae.[2]

Description

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. It digs long tunnels up to 80 centimeters deep and stores onions and tubers in underground chambers.[3]

Distribution and habitat

Spalax ehrenbergi is found in Egypt, Iraq, Israel, the Palestinian territories, Jordan, Lebanon, Libya, Syria and Turkey. The natural habitat of the mole is Mediterranean-type shrubbish vegetation, and it is threatened by habitat loss.

Possible cryptospecies

Recent cytogenetic studies have shown S. ehrenbergi may actually be a species group containing several cryptic species with chromosome numbers 2n=48, 2n=52, 2n=54, 2n=56 and 2n=58.[4]

Use in research

According to Israeli researchers at Haifa University, the Middle East blind mole-rat is the ultimate lab animal for researching cancer due to its extraordinary resistance to the disease.[3]
