Beluga whale spotted far upstream in Norway’s Drammenselva river

A beluga whale has been seen swimming unusually far inland in Norway’s Drammenselva river near Hokksund, drawing crowds of onlookers, Dagbladet reports.

The whale, typically found in Arctic waters, was observed moving upstream on Thursday, prompting marine experts to urge caution. Audun Rikardsen, a whale researcher and professor at the University of Tromsø, confirmed the animal appears to be in good condition but stressed it has strayed off course.

“This beluga is definitely a bit lost,” Rikardsen told Dagbladet. While not unheard of for the species to enter rivers, he noted it should return to the sea, where food sources are more abundant. Warmer freshwater may also accelerate the whale’s annual skin-shedding process, he explained.

Rikardsen encouraged the public to witness the rare sight—now drawing hundreds to the riverbanks—but warned against disturbing the animal. “If frightened, it risks running aground,” he said, advising boaters to keep their distance and spectators to avoid throwing objects.

Belugas, which can weigh up to 1,600 kg, have been recorded in Drammenselva before, including last summer and in 1965, when one was detonated after being deemed a “nuisance fish” damaging fishing gear.

Among the spectators was three-year-old Liam Thoresen, who watched with his father. “It’s exciting,” Liam said, unfazed by the massive marine visitor.
