The identification and distribution of mucous secreting cells in the Schaap’s dragonet, Callionymus schaapii, were demonstrated by histochemical techniques. The integument system of this fish consisted of two layers: an outer epidermis and an underlying dermis. In particular, mucous secreting cells can be classified because they were positively stained with periodic acid-schiff and alcian blue methods. As a result, the distribution of mucous secreting cells could be largely observed in all areas along the integument system, accordingly. The highest number of mucus secreting cells was found in the pectoral-pelvic area. Instead of the caudal area, which it had the lowest density of this cell. The results of this study pointed out that the pectoral-pelvic areas were the primary sites for the mucous production and of the importance to support the survival behavior, and enhance the swimming to the favorable area under the estuarine conditions.
