The presence of sacculations in the caudal region of the esophagus characterizing an esophageal diverticulum was observed in two specimens of C. mydas. This structure was also observed by WORK (2000) and WYNEKEN (2001) for green turtles in Hawaii and the Pacific. It was described as having the function of storing food before passing into the stomach, as well as
keeping food in the digestive tube for longer periods to allow for better digestion. Furthermore, the presence of sacculation
in the esophagus could be associated with a fermentation chamber in herbivorous species.
