Killer Whales Seen ‘Kissing’ for the First Time in the Wild, Photo Shows

  • Scientists recorded a nearly two-minute interaction of wild orcas gently nibbling each other's tongues in Norway's Kvænangen fjords in October 2024.
  • This rare behavior, known as tongue-nibbling, was previously only documented in captive orcas and was observed during a chance encounter by citizen scientists following Norwegian guidelines.
  • The whales repeated the gentle, face-to-face oral contact three times without aggression, closely resembling kissing-like behavior seen in captivity and thought to reinforce social bonds.
  • Marine scientist Javier Almunia noted, "Tongue-nibbling is exceptionally rare," and suggested oral contact may serve as a more versatile social communication among cetaceans given their anatomy.
  • Published in the journal Oceans, this discovery highlights how careful wildlife tourism can advance research and enrich understanding of orca culture and social dynamics in the wild.
