Vocalizations associated with pectoral fin contact in bottlenose dolphins (Tursiops truncatus).

Pectoral fin contact in bottlenose dolphins represents one form of tactile communication. Acoustic communication associated with pectoral fin contact is an additional level of communication that may change or enhance the tactile message between two individuals. In this study, we examine vocalization types associated with pectoral fin contact in a group of captive bottlenose dolphins (Tursiops truncatus).
