While these species consume a similar diet of underground plant storage organs such as roots and tubers, <jats:italic>T. splendens<\/jats:italic> has been reported to additionally consume small amounts of aerial foliage. This study aims to provide detailed gross morphological and histological morphometric analyses of the gastrointestinal tract (GIT) of these two subterranean species. The formalin fixed gastrointestinal tracts of <jats:italic>T. splendens<\/jats:italic> (<jats:italic>n<\/jats:italic>\u2009=\u20099) and <jats:italic>H. emini<\/jats:italic> (<jats:italic>n<\/jats:italic>\u2009=\u20096) were photographed, weighed and measured. The length and basal surface areas were calculated for each anatomically distinct region. Representative histological samples were prepared and stained using Hematoxylin and Eosin. Microscopic luminal measurements were used to calculate a surface enlargement factor and the luminal surface area of each region. <jats:italic>Tachyoryctes splendens<\/jats:italic> had a large double chambered hemi\u2010glandular stomach with a macroscopically visible transition from keratinized stratified squamous epithelium to glandular epithelium. The cecum was large and the luminal surface revealed a single spiral fold. The ascending colon of <jats:italic>T. splendens<\/jats:italic> was arranged in a spiral, with two centripetal and two centrifugal windings. The descending colon was arranged in a single parallel loop, similar to <jats:italic>H. emini<\/jats:italic>. A narrow colonic groove was accompanied by V\u2010shaped folds on either side. <jats:italic>Heliophobius emini<\/jats:italic> had a simple glandular stomach, a large, haustrated cecum that displayed a cecal appendix and the descending colon was arranged in a single parallel loop. The internal aspect of the colon revealed a wide colonic groove extending from the ceco\u2010colic junction to distal colon. As both species originate from a similar geographical region and ingest very similar diets, it is likely that the differences in the GIT morphology are attributed to phylogeny as the species represent two different families of mole\u2010rats.<\/jats:p>","DOI":"10.1002\/jmor.20672","type":"journal-article","created":{"date-parts":[[2017,3,30]],"date-time":"2017-03-30T03:46:39Z","timestamp":1490845599000},"page":"780-790","source":"Crossref","is-referenced-by-count":4,"title":["Comparative gastrointestinal morphology of <i>Tachyoryctes splendens<\/i> (R\u00fcppell, 1835) and <i>Heliophobius emini<\/i>, (Noack, 1894) two species of East African mole\u2010rats"],"prefix":"10.1002","volume":"278","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6854-6996","authenticated-orcid":false,"given":"Lauren","family":"Sahd","sequence":"first","affiliation":[{"name":"Division of Anatomy and Histology, Department of Biomedical Sciences Faculty of Medicine and Health Sciences, Stellenbosch University Cape Town 8000 South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniella L.","family":"Pereira","sequence":"additional","affiliation":[{"name":"Division of Anatomy and Histology, Department of Biomedical Sciences Faculty of Medicine and Health Sciences, Stellenbosch University Cape Town 8000 South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nigel C.","family":"Bennett","sequence":"additional","affiliation":[{"name":"Department of Zoology and Entomology Mammal Research Institute, University of Pretoria Pretoria 0002 South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanet H.","family":"Kotz\u00e9","sequence":"additional","affiliation":[{"name":"Division of Anatomy and Histology, Department of Biomedical Sciences Faculty of Medicine and Health Sciences, Stellenbosch University Cape Town 8000 South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,3,29]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.2307\/1379688"},{"key":"e_1_2_6_3_1","first-page":"173","article-title":"Vergleichemd\u2010und funktionall\u2010 anatomische Untersuchungen am caecum und colon myomorpher Nagetiere","volume":"186","author":"Behmann H.","year":"1973","journal-title":"Zeitschrift Fur Wissenschartliche Zoologie"},{"volume-title":"African mole\u2010rats: Ecology and eusocilaity","year":"2000","author":"Bennett N.
