Behavioral Responses to Underwater Sound in the Small Benthic Octopus Octopus ocellatus
cephalopod hearing octopus
2009/8/19
To explore behavioral responses to sound and the detectable frequency range of Octopus ocellatus, responses of the octopus to 120 dB rms sound stimuli of various frequencies were observed. The octopus...
