Cruising Alaska: May/June 2006

In bubble net feeding, the whale releases air from it's blow hole as it swims upward in a spiral pattern. The bubbles trap small fish and krill that the whale is after. The whale then swims up through the centre of the bubble net with its mouth open, as you see here. To make it even more impressive, the whale sings as it does this, and we listened to the singing on Floyd's hydrophone!
