Abstract: To study the comparative histological observation of skin in male and female frog (Rana dybouwskii) during breeding season, using paraffin section and hematoxylin-eosin staining. The results showed that: there were significant differences between male and female frogs in the types of total thicknesses of the head and the trunk dorsum and abdomen. The dorsal in females was extremely thicker than in males. The abdominal in males was highly significant thicker than in females. In males the lateral trunk was significantly thicker than in females. There were two kinds of glands present, namely mucous glands and granular glands and they were found throughout the skin of the body. Typical granular glands were larger than mucous glands. In addition, we observed the type of the specialized mucous glands in males. It might be related to the reproduction, breath, and defense functions.
