Abstract :Histological examinations were conducted in order to describe the tissues on the stomach of the critically endangered Lyciasalamandra fazilae (Başoğlu and Atatür, 1974) and L. flavimembris (Mutz & Steinfartz, 1995). In this study two adult females, two adult males and one juvenile from Dalyan, Turkey (L. fazilae) and one adult male and one juvenile from Marmaris, Turkey (L. flavimembris) were examined. Tissue samples were taken from the freshly dead animals found on the road during the night field work. They were taken into alcohol for the histological studies. Tissue samples were fixed in Bouin’s solution and routine histological techniques were applied. Hematoxylin and Eosin stains were used to identify cells and structures of the tissues. Stomach is covered with gastric columnar epithelial cells and glandular epithelium which are contained with gastric glands. Tunica mucosa, tunica submucosa, tunica muscularis and tunica serosa were observed as mucosa layers. There was no significant difference between males and females in mucosa layers where gastric glands are situated. The histological structure of stomach of both species between males and females and between adults and juveniles were found to be mostly similar. Results from the literature review has indicated that the stomach histology show a similarity with the other Urodela species.
