We used light microscope to observe the histological characteristics of the dorsal, ventral skins and lungs of Bombina maxima, Megophrys glandulosa, Bufo gargarizans, Hyla gongshanensis, Rana chaochiaoensis, Dianrana pleuraden, Gynandropaa yunnanensis, Rhacophorus gongshanensis, Polypedates megacephalus, Microhyla fissipes, Kaloula verrucosa (Table 1). The results showed that the blood vessels in the back and the abdomen were interlaced into reticular veins. The morphological characteristics of dorsal skins, abdominal skins and lungs of these species were different (Table 2). The skin consisted of the epidermis and dermis (Table 3). Except for Hyla gongshanensis, the remaining 10 species had lamina calcarea distributed between the stratum spongiosum and stratum compactum of the dermis (Fig. 1). The pigment cells were located in the stratum spongiosum, with the dorsal pigment layer more developed. The alveolar sac, shaped hollow with dense blood vessels (Fig. 3), were divided into the right and left lobules of the same size. The lung was composed of pulmonary cyst wall, septum (Table 4), capillary and pulmonary alveoli. The pulmonary cyst wall consisted of the pleural layer, the middle layer and the inner layer: the pleural layer was composed of flat cells; the middle layer was composed of connective tissue; the inner layer was composed of pulmonary alveoli and capillaries; and the septum was composed of capillaries and connective tissues (Fig. 4). In these 11 species, individuals with more developed lungs tended to have reduced mucous glands in the skin structure. Individuals with more developed lungs had reduced mucous glands in their skin structure, and their histological features showed greater adaptation to the environment and less influence from phylogenetic relationships.
