Though at first glance dolphins appear to be just happy aquatic animals, this program makes it clear that they are also highly intelligent creatures. Find out how eager dolphins cooperate with humans and other animals in different settings. Notice how, like humans, they seem to need physical contact with each other as they stroke each other with their flippers. The program also explains how they appear to thrive almost exclusively in groups led by a strong and powerful leader. Find out why scientists enjoy performing experiments with these creatures who often appear to figure out the nature of the experiments being run almost before it's time for them to begin participating.
