Abstract: The morphology of the digestive tube of the green turtle (Chelonia mydas) was evaluated. Nine young e 1 adult turtles were analyzed. The digestive organs withdrew occurred after plastron opening. The length's description and measurement from each organ [esophagus, stomach, small intestine (SI) and large intestine (LI)] were made with digestive tube opened. The results showed that in both the adult and young animals, the esophagus from all species were marked by the presence of pointed papillae on internal mucous. The stomach presented saclike shape with blind fund. In the SI, reticular pleats in the duodenal mucous membrane have been observed, while the jejune and the ileum showed rectilinear longitudinal pleats. The LI was marked by the alternation of arched areas (haustra or sacculations) and narrowings. The microscopy of digestive tube from C. mydas revealed esophagus with folded mucous covered by keratinized and stratified squamous epitheliums. The stomach was divided in regions: cardiac, fundic e pyloric which differed as to the number of glands and the muscle layer's arrangement. The SI presented marked by microvillus, and LI by folded mucous with glands the lamina propria. The morphology of the tube digestive of the green turtle showed to be adapted to your eating habits. A long the digestive tract and specializations provide greater area of absorption and more efficiency in digestion in this species.
