This species is considered the most endangered marine mammal in the western South Atlantic Ocean. Anatomic dissection of the digestive system of 19 animals of different ages, including 2 neonates, 12 juveniles, and 5 adults, was performed. Parameters related to length, breadth, weight, and diameter of the digestive viscera were considered in each case. Our results show that the Franciscana dolphin presents differential characteristics in relation to several parts of the digestive system, including, specifically, the tongue, the teeth, the stomach, and the small intestine. Thus, this paper add precious information to the actual knowledge of this vulnerable marine mammal species in order to improve conservation efforts.<\/jats:p>","DOI":"10.3390\/ani14050661","type":"journal-article","created":{"date-parts":[[2024,2,20]],"date-time":"2024-02-20T07:50:26Z","timestamp":1708415426000},"page":"661","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Nature or Nurture: Is the Digestive System of the Pontoporia blainvillei Influenced or Determined by Its Diet?"],"prefix":"10.3390","volume":"14","author":[{"given":"Carlos","family":"Tostado-Marcos","sequence":"first","affiliation":[{"name":"Fundaci\u00f3n Mundo Marino, Av.
