Episode 313 - Cross continent pop hits from whales and deep divers

February 11, 2019

The greatest pop hits can cross continents, but what about oceans? We all know whales make songs, but not only are they very complex, they can be covered, repeated and spread like a Number 1 summer hit across oceans to the far flung corners of the globe. Plus reaching the deepest depths of the ocean is tough for humans, but easy for whales. How do they accomplish these great feats? We also touch on the impact of naval sonar on the battle between squids and whales.
