Taste buds are one of the most determinant structures of the general behavior of the fish, particularly the feeding behavior. By examining the distribution pattern of this sense organ in the fish body, the behavioral responses of the fish to different physical conditions might be predicted. In this aspect, the taste bud distribution pattern of the Black Sea anchovy, Engraulis encrasicholus, was investigated. The gills and the upper and lower jaws were observed and photographed in a scanning electron microscope. Taste buds of Black Sea anchovy are distributed only in the epithelium of the oral cavity and pharynx. Taste buds are between the gill teeth on the gill rakers' edge. Taste buds were also seen close to the teeth on the pharynx. No taste buds were found on the lips, the oral valve, and the whole-body surface. In conclusion, the Black Sea anchovy has taste buds only in the mouth and between gill teeth in the gill rakers, and no external taste buds even on the lips, as a typical characteristic of pelagic plankton feeders.References
