Extremely close underwater encounter with Killer Whale

This daredevil takes a swim with wild killer whales in Norwegian Sea. A tense moment occurs when an orca chases a herring but lets go right before impact with a swimmer. Insane! Shortly after you can clearly see that the orca dives deeper, precisely turning aside to take a good look at the diver. At the same time, you can hear the sonar sound orca is sending out to recognize the object. Every winter they migrate here and along the coast of Norway after herring.
