Macroscopic study of the digestive tract of Gracilinanus microtarsus (Wagner, 1842) (Mammalia: Didelphidae)
Gracilinanus microtarsus is a small marsupial species belonging to the Didelphidae family. It has an omnivorous/frugivorous feeding habit and, therefore, it has a great ecological importance, because it is a seed-dispersing species. This article aims to describe the macroscopic morphology of the dig...

The animals under study had the dental formula 2x I 5/4 C 1/1 P 3/3 M 4/4. This is the dental formula of the whole Didelphidae family. The dorsum of the tongue had vallate, fungiform, and filiform papillae. Tubular esophagus evidenced the cervical, thoracic, and abdominal portions. The unicavitary stomach consisted of glandular and aglandular region and gastric folds. Small intestine had 3 portions: duodenum, jejunum, and ileum. Large intestine consisted of: cecum, colon, and rectum. Parotid salivary gland was the largest and it had a flattened shape. The sublingual salivary gland, whi h was the smallest, had a flattened and elongated shape. Mandibular salivary gland had an oval shape. Pancreas had a dispersed shape and lobulated aspect. Liver had a dome shape and it consisted of the lobes right medial, square, right side, left medial, left side, and caudate. The digestive tract of the animals under study is similar to the marsupial species described in the literature.https://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2014v27n1p109Digestive tractGuaiquicaMacroscopyMarsupials |

Gracilinanus microtarsus is a small marsupial species belonging to the Didelphidae family. It has an omnivorous/frugivorous feeding habit and, therefore, it has a great ecological importance, because it is a seed-dispersing species. This article aims to describe the macroscopic morphology of the digestive tract in G. microtarsus. We used 4 animals fixed in 10% formaldehyde. The organs were dissected, measured, and photographed. The animals under study had the dental formula 2x I 5/4 C 1/1 P 3/3 M 4/4. This is the dental formula of the whole Didelphidae family. The dorsum of the tongue had vallate, fungiform, and filiform papillae. Tubular esophagus evidenced the cervical, thoracic, and abdominal portions. The unicavitary stomach consisted of glandular and aglandular region and gastric folds. Small intestine had 3 portions: duodenum, jejunum, and ileum.
