Russian 'Spy' Whale Travels to Sweden, Raising Health and Mating Concerns

Hvaldimir, a beluga whale believed to have been trained by the Russian military, has been spotted off the coast of Sweden after first appearing in Norway in 2019.
Experts are unsure why Hvaldimir traveled to Sweden so quickly but speculate he may be searching for food, mates, or other belugas.
Though Hvaldimir seems healthy, concerns have been raised over his weight loss and ability to find food in Sweden.
Hvaldimir was found wearing a harness with Russian military markings, leading experts to believe he was used for surveillance.
The whale is known for being friendly towards humans and may have been lonely, as he has not interacted with other belugas since arriving in Norway.
