ECHOLOCATION-TYPE SIGNALS BY TWO DOLPHINS, GENUS SOTALIA.
Abstract
Two captive Amazon river, or sacred, dolphins, Sotalia fluviatilis, were studied for a short time in captivity in Florida. Both animals, a female and her immature male offspring, produced pulsed click-trains which behaviorally were correlated with environmental exploration and which thus were presumably being used for echolocation. Sonagrams of these sounds are presented. No sounds of the type usually termed a whistle were heard. (Author)
