The aim was to provide a comprehensive anatomical comparison between the different species. The relative shape, length, and surface areas were taken into account to determine whether the GITs are phylogenetically constrained or exhibit anatomical adaptations in response to diets. In all six species the stomach was simple and glandular. With the exception of <jats:italic>Heterocephalus glaber<\/jats:italic>, the caecum was coiled in a flat spiral, the ascending colon was arranged in a loop of varying lengths, and a mucosal colonic papillary\u2010lined groove was present in the ascending colon in all species. By contrast, the caecum in <jats:italic>H. glaber<\/jats:italic> was uncoiled, the ascending colon was not looped, and the groove was not papillated. A caeco\u2010appendix was observed only in <jats:italic>Bathyergus suillus<\/jats:italic> and <jats:italic>Georychus capensis<\/jats:italic>. Hierarchical multivariate cluster analysis on the presence\/absence of nine anatomical structures associated with the GIT of mole\u2010rats revealed that <jats:italic>H. glaber<\/jats:italic> was anatomically the least similar of the six species (77.6% similarity) with respect to the nine GIT variables included. All <jats:italic>Cryptomys<\/jats:italic> species were the same (100% similarity), and two species <jats:italic>B. suillus<\/jats:italic> and <jats:italic>G. capensis<\/jats:italic> grouped together and were more similar to the <jats:italic>Cryptomys<\/jats:italic> genus (95% similarity) than they were to <jats:italic>H. glaber.<\/jats:italic> These findings support previous phylogenetic classifications. The voluminous caeco\u2010colon in <jats:italic>B. suillus<\/jats:italic> may be explained by its ingestion of grasses in addition to below\u2010ground storage organs of plants. We conclude that phylogeny and diet affect the GIT anatomy of the African mole rats studied here. J.
