Characteristic sounds in the sonic range made by captive dolphins, or porpoises, were heard and recorded using underwater listening gear. The phonations described include those elicited by strange objects, those which accompany feeding activity, a distinctive sound heard during the mating season, and others less clearly associated with particular circumstances or stimuli. T. truncatus is highly vocal, a characteristic which may apparently be related to certain behavioral traits and to its usual coastal or inshore environment. On the other hand, only two types of phonation have definitely been attributed to S. plagiodon, an offshore species whose behavior differs in many respects from that of Tursiops. Previous accounts of popoise sounds and the circumstances attending their production are reviewed.
