Guided by the principle of "in their world, on their terms," Denise Herzing and her team of researchers track and observe a pod of wild Atlantic spotted dolphins in the Bahamas. Using non-invasive techniques to build trust, they can see how the dolphins behave in the most natural setting: their own home. Charles Annenberg Weingarten and the explore team get a firsthand look into the underwater world of these highly social and intelligent creatures.
