Richard Karoliussen is dead serious when it comes to studying and researching orcas in his native Norway. Most of the time, anyway.
He and Eve Jourdain (pictured below, left and right) are co-founders of the research group Norwegian Orca Survey.
And during an outing a few months back, they came across a pod of killer whales.
And Richard simply couldn’t resist: He started whistling. And the way these majestic giants of the sea responded is nothing short of incredible!
