For decades, scientists have been fascinated by dolphins’ distinctive vocal patterns learned early and used throughout life. New research reveals that these so called “whistles” actually demonstrate that dolphins respond selectively to their personal signatures, much as a person reacts to someone calling their name.
The result is a landmark, providing a clear parallel between dolphin and human communication.
Dolphins have an extensive vocal repertoire, much of which remains unexplored. More experiments would help illuminate the meanings they attach to their signature whistles.
