David Attenborough comments on how spotted dolphins swimming in the bow wave of his boat seem to enjoy human company. Underwater shots show of a school of 60 spotted dolphins in clear waters off the Bahamas and David swims with them and listens to their chatter. They use ultrasonic clicks and whistles to communicate - 30 different sounds, all with different meanings. Every dolphin has its own whistled name, and babies inherit a name derived from their mother's. The dolphins also use touch and posture to communicate - the posture changes the meaning of a sound, giving them a huge vocabulary. They have the most complex commincation system of any animal. They mimic each other's and David's movements in the water.
