We covered a lot when it comes to these huge aquatic mammals but there was one big topic we didn't get to: and that's how whales communicate.  We'll learn more about the sounds whales make: singing, whistles, and echolocation clicks with Amy Van Cise, a biologist at NOAA Northwest Fisheries Science Center in Seattle, Washington.
