This underwater picture shows a female killer whale (Orcinus Orca) with scars near the dorsal fin, patroling near Skjervoy Fjord, in northern Norway within Arctic Circle, on November 11, 2024. Dozens of killer whales and their family clans including calves, follow millions of hearings gathering in the northern Norway fjords from October to January, to eat them. Increasingly frequent and northerly sightings suggest that the iconic black and white member of the dolphin family, whose males can grow up to eight metres (26 feet) long and weigh six tonnes, eating about 50 to 70 kg of hearings per day, is learning to adapt also to the newly melted waters of the Arctic Ocean.
