Abstract
Lateralized behavior in Guiana dolphins, Sotalia guianensis, at Pipa Beach, RN, Brazil
Highlights
In this study, we report data on possible behavioral asymmetries at the population level in Guiana dolphins, Sotalia guianensis van Bénéden, 1864, at Madeiro Bay, Pipa Beach (6° 13’ S and 35° 04’ W), southern of Rio Grande do Norte, Brazil
We observed 190 active behavioral events for 28 sampling days, for a total of 224 h of effort, in which dolphins were present for 148.4 hours
The foraging has been the predominant behavior according to the activity budget, lateralized events were more common during the socializing (p < 0.001, Figure 1a)
