The following results were obtained in the ultrastructural observations on the skin of a mormyrid fish (Gnathonemus petersii). The characteristics of the skin structure of this fish were the presence of ver flat cells in the middle layer of the epidermis and mucoid-containing vesicles in the cytoplasm of the epiderma cell. Melanophores were observed in the epidermis and dermis. The epidermal melanophores were located in the inner layer of the epiderms. Sometimes, the melanophores in the process of melano-some-synthesis were observed in the epidermis. The dermal melanophores were found just beneath the basal lamina, and also in the deeper dermis. They were 250-300μm in diameter. Therefore, the dermal melanophores fall into hte category of so-called “macromelanophore.”
