“…Because it has a diversified diet, the species needs anatomical and habitual characteristics that help it to obtain its meals. Such aspects have already been described in works that addressed morphological aspects of the stomach (Cavalcante et al, 2021) and the tongue (Silva et al, 2015) and reported adaptive changes that this animal has due to diet and metabolism (Ferigolo, 1985;Nogueira et al, 2014).…”

Euphractus sexcinctus has a diverse diet, so it needs anatomical and habitual features to help it get its meals. Therefore, the objective is to study the morphology of the small and large intestines of the six‐banded armadillo (E. sexcinctus). The research was authorized and approved under number 136/16. Six animals, obtained from victims of predatory hunting, were dissected for the research. For the anatomical analysis, the specimens were dissected and photographed. The fragments of each organ were submitted to histological routine to obtain slides stained with hematoxylin–eosin, toluidine blue and Masson's trichrome for further analysis. The small intestine has three parts: duodenum, jejunum, and ileum. Histologically, it has the typical four layers of tubular organs. The mucosa is covered by simple cylindrical epithelium with the presence of specializations in the form of microvilli and variation in the number of goblet cells, depending on the portion observed. In the duodenal portion, the presence of the serous layer was not observed. In the jejunal portion, it is possible to observe lymphoid tissue aggregates in the submucosa, which become more evident in the ileum. The large intestine is divided into cecum, colon, and rectum and has the same histological subdivisions as the small intestine, but with some specializations. The presence of simple cylindrical intestinal crypts is clearly observed and the presence of a large number of goblet cells, which increase as it approaches the rectum. In the submucosa of the large intestine, the presence of organized lymphoid plaques is detected.Research Highlights The presence of large numbers of goblet cells, which increase as one approaches the rectum. The presence of organized lymphoid plaques is detected. The duodenal portion was not observed presence of the serous layer.
