Abstract:

To study the microstructure of skin of Salamandrella keyserlingii, using paraffin section and hematoxylin-eosin staining. The results were as follows: the skin structures were basically the same as Salamandrella keyserlingii throughout the body, composed of epidermis and dermis. However, there were inter-position differences in skin thickness. The skin of the back was the thickest, the other of the abdomen was thinnest. Mucous and granular glands were rich in dermal, in the abdomen skin there were many mucous glands and in the dorsal skin there were many larger granular glands. Moreover, there were specialized mucous glands in dermal of the back. Dermal melanocytes shallowly scattered mainly in dermis. The capillaries which under the epidermis were found. The skin structure of Salamandrella keyserlingii indicated its adaption to live in the moisture areas.
