| Abstract: | We conducted behavior experiments on the roles of vision, olfaction, and the lateral line in feeding in tongue sole Cynoglossus semilaevis Günter. Chemical cues from the prey alone could not elicit any searching or attacking behavior by the fish; only when moving
foods were presented, the chemical nature of the foods affected feeding. In addition, we found that normal tongue sole did
not accurately recognize moving artificial prey of different shapes. Neither chemosense nor vision plays an important role
in prey detection. Reactions to moving objects and the response of the oropharyngeal cavity to different foods showed that
the (eyeless) tongue sole use mainly the lateral line for prey detection and capture. Gustation in the oropharyngeal cavity
is essential for the fish to swallow its prey. |
