Hearing is an important sensory system for most species of fish. For example, in the family Batrachoididae, males use their swim bladders to make advertisement calls which females use to localize males. Hearing threshold and the ability to localize sound sources are reduced underwater, in which the speed of sound is faster than in air. Underwater hearing is by bone conduction, and localization of sound appears to depend on differences in amplitude detected b… WebJun 15, 2024 · For this day’s outing, the boat arrives at the diving location a few miles off the coast and anchors.

WebSensitivity to sound, in terms of both the lowest sound levels ( loudness or amplitude) and range of frequencies that can be detected differs among fish species. One factor affecting the levels and range of frequencies that a fish can hear is the proximity of the swim bladder to the inner ear. The gas within the swim bladder has a density that ...
