Many mammals like to dig in the dirt, but few call it home. Those that do, such as mole-rats, zokors and tuco-tucos, have developed novel adaptations to their subterranean life, including bones and muscles modified for efficient digging and ways to "see" underground without using their eyes. These unusual traits, adopted independently by unrelated groups around the world, also make subterranean rodents fascinating subjects for biologists. "Life Underground" provides the first comprehensive review of the biology of subterranean rodents. Arranged by topic rather than by taxon to facilitate cross-species comparisons, chapters cover such subjects as morphology, physiology, social behaviour, genetic variation and evolutionary diversification. Two main questions run throughtout the book. First, to what extent has subterranean life shaped the biology of these animals, leading to similar adaptations among otherwise dissimilar species? Second, how have the distinct evolutionary histories of these groups led to different solutions to the challenges posed by life underground?
