Abstract
IT IS generally conceded that, in many fishes, gustation plays an important role in the procurement of food. The lips and palatal region of fishes are generously supplied with taste buds. Particularly in barbeled fishes, the fact that numerous taste buds are arranged in the epidermal layer of barbels is confirmed by various investigators (e.g., Herrick, 1904; Landacre, 1907; Baecker, 1926; Sato, 1937c). According to Sato (1937b), the sea catfish, Plotosus anguillaris (Lacepede), bearing eight barbels around the mouth, is capable of locating food substances by both gustatory and olfactory organs. In some fishes, the gill rakers are said to aid in the concentration of food materials.
