While morphological observations of the species have described its oesophagus, little is known about the other organs constituting the tubular digestive tract. Therefore, the objective of this study was to describe the morphological aspects of the tubular portion of the digestive tract of this species. Ten adult specimens were analysed. After fixation in 10% formalin, organ fragments were embedded in paraffin using the routine histological technique. Sections of 5\u2009\u03bcm thick were stained with haematoxylin\u2013eosin (HE), Gomori trichrome (GT) and Alcian blue (AB) pH\u20090.4 and 2.5. The tubular portion of the digestive tract of <jats:italic>K. s. scorpioides<\/jats:italic> consisted of the oesophagus, stomach, small intestine (duodenum, jejunum and ileum), large intestine (caecum and colon) and cloaca. The wall of the tubular portion of the digestive tract of <jats:italic>K. s. scorpioides<\/jats:italic> was made up of four concentric layers: Mucosa, submucosa, muscularis externa and adventitia or serosa. The morphology of the tubular digestive tract of adult <jats:italic>K. s. scorpioides<\/jats:italic> described in this study shows structural patterns appropriate to their omnivorous feeding habits, such as a simple glandular stomach, long intestines, a well\u2010developed caecum and the production of mucosecretions throughout the digestive tract. This study provides insights into the digestive physiology of the species and provides data for comparative analyses.<\/jats:p>","DOI":"10.1111\/ahe.70043","type":"journal-article","created":{"date-parts":[[2025,5,22]],"date-time":"2025-05-22T10:40:43Z","timestamp":1747910443000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Morphology of the Tubular Portion of the Digestive Tract of\u00a0Free\u2010Living <i>Kinosternon scorpioides scorpioides<\/i> (Linnaeus, 1766)"],"prefix":"10.1111","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4324-3761","authenticated-orcid":false,"given":"Diego Ferreira","family":"de Sousa","sequence":"first","affiliation":[{"name":"Programa de P\u00f3s\u2010Gradua\u00e7\u00e3o em Sa\u00fade e Produ\u00e7\u00e3o Animal na Amaz\u00f4nia (PPGSPAA) Universidade Federal Rural da Amaz\u00f4nia (UFRA)  PA Brazil"},{"name":"Instituto de Sa\u00fade e Produ\u00e7\u00e3o Animal na Amaz\u00f4nia (ISPA) Universidade Federal Rural da Amaz\u00f4nia (UFRA)  PA Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7656-1109","authenticated-orcid":false,"given":"Andrea","family":"Bezerra","sequence":"additional","affiliation":[{"name":"Instituto de Sa\u00fade e Produ\u00e7\u00e3o Animal na Amaz\u00f4nia (ISPA) Universidade Federal Rural da Amaz\u00f4nia (UFRA)  PA Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8979-9338","authenticated-orcid":false,"given":"Erika","family":"Branco","sequence":"additional","affiliation":[{"name":"Instituto de Sa\u00fade e Produ\u00e7\u00e3o Animal na Amaz\u00f4nia (ISPA) Universidade Federal Rural da Amaz\u00f4nia (UFRA)  PA Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7833-1334","authenticated-orcid":false,"given":"Elane Guerreiro","family":"Giese","sequence":"additional","affiliation":[{"name":"Instituto de Sa\u00fade e Produ\u00e7\u00e3o Animal na Amaz\u00f4nia (ISPA) Universidade Federal Rural da Amaz\u00f4nia (UFRA)  PA Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5668-7911","authenticated-orcid":false,"given":"Ana Rita","family":"de Lima","sequence":"additional","affiliation":[{"name":"Instituto de Sa\u00fade e Produ\u00e7\u00e3o Animal na Amaz\u00f4nia (ISPA) Universidade Federal Rural da Amaz\u00f4nia (UFRA)  PA Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,22]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.48550\/arXiv.1610.01717"},{"key":"e_1_2_10_3_1","unstructured":"Berry J.
