The organs and divisions of the gastrointestinal tract are similar to those of mammals. The lizard has a simple, J-shaped, elongated stomach. A caecum is present in many species. The large intestine is thin-walled and less muscular than the stomach or small intestines.

[[Lizard Feeding|Herbivorous]] lizards such as the [[Green Iguana|green iguana]], [[Prehensile-tailed Skink|prehensile-tailed skink]], [[Spiny-tailed Lizard|egyptian spiny-tailed lizard]] and [[Chuckwalla|chuckwalla]] (''Sauromalus obesus'') have a sacculated colon to facilitate hindgut fermentation. These animals usually have higher [[Preferred optimum temperature zone|optimal body temperature zones]] in order to enhance microbial fermentation.
