<jats:p>The ability to determine the direction of sound sources is a fundamental function, which has been commonly observed in many vertebrate species in all major groups from fish to mammals. It is well known that terrestrial vertebrates including humans use binaural cues such as interaural time and intensity differences to localize sound sources. However, how fish perform sound localization has been puzzling researchers for many decades since Karl von Frisch. In this talk, I will highlight some behavioral, anatomical and physiological work addressing the question of directional hearing in teleost fishes, primarily focusing on two fish species—the oscar, Astronotus Ocellatus and the sleeper goby, Dormitator latifrons, during my postdoctoral research with Art Popper at the University of Maryland, College Park, and later in my lab at the University of Miami. Most of the studies were conducted using the Fay shaker apparatus that can provide directional stimulation simulating underwater acoustic particle motion in the three dimensional space. Results of this work help us understand behavioral detection ability and peripheral neural encoding of acoustic particle motion in fish.</jats:p>
