Why Cephalopods are Probably Not "Deaf"

Abstract

Moynihan (1985) proposed hypothetical arguments about why cephalopods are deaf. "Hearing" in cephalopods has been a subject of discussion for 75 years, but surprisingly, Moynihan (1985) did not consider the available morphological and physiological data. The author would like to summarize these data briefly and add some behavioral information that, in contrast to Moynihan's hypothesis, indicates that cephalopods can perceive underwater vibrations.
