The ocean is a world of sound where whales sing, dolphins click and seals bark, all in a bid to survive. Join Expedition Leader Diana Lopez for a fascinating look at how marine mammals use sound to navigate, communicate, feed and stay safe underwater. From the haunting songs of humpbacks to the echolocation of porpoises, learn how each species has adapted to its own acoustic niche—and how rising underwater noise pollution threatens to drown them out. Discover how sound can be both a survival tool and a window into conservation.
