In C. mydas, L. olivacea and E. imbricata, the stomach was J-shaped, and the mucosa was characterized by longitudinal folds. This same pattern of folds had already been described by PARSONS & CAMERON (1977) for C. mydas, and by WORK (2000) for sea turtles in general. The stomachs of C. caretta had two patterns: tubular with longitudinal folds, as described by RAINEY (1981); or with a sacculation in the cranial and caudal regions. Those sacculations
had not been previously described. More studies are needed to identify the function of this saccular region in C.
caretta, a carnivorous species. In addition, more specimens should be examined, and histological examinations in particular would be useful to verify the most frequent pattern in the stomachs of this species.
