A melody from below

It is not unusual for us to hear a singing whale through the hull of our boat without the aid of our hydrophone. This means the whale is VERY nearby. The other day we were sitting with the engines off recording a whale that we could easily hear without the hydrophone. As I gazed into the water I saw a dark shape underneath us, and quickly recognized that this was our singing whale. We put our GoPro camera in the water and captured this video of the whale with its head down in typical singing posture.  This was a first for our research team!
