These brainy marine mammals can "read," plan ahead, and communicate in astounding ways. Aired February 9, 2011 on PBS. Program Description Off the coast of Honduras, on Roatan Island, a legendary experiment in dolphin communication is being attempted for the first time in 20 years—one that could prove that dolphins can, in effect, "speak" with one another to coordinate their behavior. Other studies reveal that these playful marine mammals can plan ahead and problem-solve in ways few other animals can.
