The present study about geographic variation in tropical common bottlenose dolphin whistles showed variation between oceanic (Revillagigedo Archipelago, Pacific Ocean, Mexico; Saint Peter and Saint Paul Archipelago, mid-equatorial North Atlantic Ocean, Brazil) and coastal populations (the western Coast of Aragua, South Caribbean, Venezuela). Environmental acoustic adaptations, variances in vessel traffic among locations, and other possible causes associated with the geographic differences are discussed. The current study is the first step towards providing an overview of geographic whistle variation among the herein assessed locations. Future studies should focus on a fine-grained comparison of variations between whistle types, measure ambient noise levels in each location, and incorporate acoustic propagation modeling.
