Histological sections of the skin in two amphibian species, Salamandra salamandra (A) and Lithobates pipiens (B). The epidermis was composed of a stratum germinativum with stratified epithelium and a stratum corneum (arrow) with flattened keratinized cells. The dermis consisted of an outer stratum spongiosum and the underlying stratum compactum. Mucous glands and chromatophores (asterisk) were embedded in the stratum spongiosum. A capillary network of numerous small capillaries (indicated by arrowheads) was located in a plane directly beneath the epidermis. A network of larger arteries and veins was located in the subcutis. e, epidermis; d, dermis; mg, mucous gland; s, subcutis; sc, stratum compactum; sg, straum germinativum; ss, stratum spongiosum.
