A Cryptic Subterranean Mammal Species, the Lesser Blind Mole Rat ()-Retreated but Not Extinct.

Blind mole rats (genus ) attract a great deal of attention because of their cancer resistance and longevity. Due to the high rate of chromosome rearrangements, 74 chromosomal forms have been discovered. The convergence of their external morphology complicates their taxonomy, and many cryptic species remain unrecognized.
