Two isolated dolphins (Tursiops truncatus) were provided with an electronic acoustic link during alternate periods of approximately 2 minutes. The dolphins repeatedly communicated in a tight sequence when the acoustic link was connected. Their responses varied as the experiment progressed. Some information regarding possible meaning of the whistles was obtained.
