The transition from the small to the large intestine was characterized by an ileocecal sphincter in all species studied.
However, in D. coriacea a small lateral pouch extending from the side wall next to the ileocecal sphincter was present (Fig. 13). Regions of the large intestine (LI) were difficult to identify macroscopically due to the absence of defined limits. In C. mydas, L. olivacea, E. imbricata and C. caretta the LI was identified by the alternation of saccular and narrow regions. The saccular regions had a smooth mucosa, probably because of the accumulation of feces, and a narrow region with rectilinear folds. The caudal region, near the cloaca, was characterized by evident rectilinear folds. In D. coriacea, the LI had irregularly
distributed mucosal folds along its entire length (Fig. 14).
