The mass stranding of dolphins, orcas and whales is depressingly common. We join a team on the East Coast of the United States who have dramatically improved the survival rates of beached dolphins there. And we are with them as they fight to save a dolphin mother and calf. Plus we look at how Silicon Valley AI tech, and its power to understand dolphin communication, could lead to even more being saved. Produced and Presented by Ben Wyatt Picture credit: Getty Images
