Some authors (PARSONS & CAMERON 1977, RAINEY 1981, WORK 2000, WYNEKEN 2001, PRESSLER et al. 2003, MAGALHÃES et al. 2010) describe that the esophagus of sea turtles is generally covered with pointed and keratinized papillae, the stomach is curved and situated to the left of the coelomic cavity, and its mucosa is generally folded. The lining of the small intestine is textured and, in many species, it is “honey-combed” in appearance. The large intestine is
divided into the cecum, the colon and the rectum. The cecum is the most proximal region. The largest portion is the colon and there, distally, a narrowing occurs, forming the rectal muscle. According to WYNEKEN (2001), the length of the gut is somewhat related to the animal’s diet, being proportionally longer in green and leatherback turtles than in loggerheads, ridleys, and hawksbills.
