Fish hearing involves one or more of the otolith organs. Behavioral studies
show a set of `auditory filters' operating in the range from below 40 Hz to above 1 kHz, with the high-frequency
limit depending on species. Behavioral data on the sense of hearing of gold-fish indicate that frequency analysis
is a basic feature of hearing, as is the case for all other
vertebrates investigated. Saccular a¡erents are to some
degree frequency-selective
