The Lateral Line and Sound Reception

“…Tavolga (1976) has suggested that Arius felis (the sea catfish) uses the lateral line in sound based obstacle detection, and he indicates a distance limit of only a few centimeters. Similar short response distances have been reported by several authors for reactions proposed to depend on lateral line stimulation (Wunder 1927, von Frisch and Dijkgraaf 1935, Reinhardt 1935.…”

THE FUNCTIONING and SIGNIFICANCE OF THE LATERAL‐LINE ORGANS

“…Hofer concluded that the fish could 'feel at a distance' with its lateral lines. Hofer 's results have been confirmed and extended repeatedly with many different species, including elasmobranchs (Parker, 1909 ;Dotterweich, 1932), bony fishes (Wunder, 1927; Dijkgraaf, 1934; Hahn, 1960) and amphibians (Scharrer, 1932; Kramer, 1933; Dijkgraaf, 1947). In all cases reactions of blinded animals to weak water currents impinging locally on the body or to the near approach of moving objects were observed; in some instances even perception of motionless obstacles at a small distance was seen.…”

Density and distribution of external taste buds in cyprinids

“…Thus in species and environments where vision is only of limited use (Huber & Rylander 1992) the external taste system may increase in importance for detecting food. External taste may serve for gradient search, as in catfish, but generally elicits ingestion upon contact (Atema 1971, Bardach & Atema 1971, Kapoor et al 1975, Wunder 1927. Touch seems as important for triggering this feeding reflex as chemo-stimulation (Davenport & Caprio 1982).…”
