"Humpback whales blow bubbles around schools of fish to concentrate them for easier capture. It's called a bubble net, says David Wiley, research coordinator for Stellwagen Bank National Marine Sanctuary, and it's visible as a ring of bubbles at the surface. Now, with underwater digital tracking tags and custom visualization software, whale researchers can see what the whales are doing underwater when they're bubble-netting. Humpbacks are the only whales known to blow bubble nets -- a circle of bubbles that traps schools of fish for easy capture. Although this hunting technique has been documented in humpbacks for decades, just how whales make the nets wasn't well-understood until now, says David Wiley, a biologist with NOAA. Wiley and colleagues attached digital tags to Humpbacks' backs to find out what they do underwater when they're bubble-netting."
