The stomach of C. caretta presented a curved tubular form on the left side of the animal, and then moved slightly to the
right forming the first intestinal loop. The stomachs of the two specimens studied differed. In one animal the cranial and caudal regions presented sacculations, both devoid of mucosal folds, whereas the intermediate portion of the stomach was
larger and marked by longitudinal folds (Figs 5 and 6). By contrast, the other animal did not present sacculations in the stomach, and longitudinal folds were observed along the entire mucosa (Fig. 7).
