Hvaldimir the tame beluga whale was indeed a Russian spy whale, but it escaped because it was a "hooligan." Sadly Hvaldimir died earlier this year.

According to Dr Shpak, Andruha/Hvaldimir had first been captured in 2013 in the Sea of Okhotsk in Russia's Far East. A year later it was moved from a facility owned by a dolphinarium in St Petersburg to the military programme in the Russian Arctic, where his trainers and vets remained in contact.

The Hvaldimir whale - which was spotted off the coast of Norway in 2019 - was originally thought to have been a Russian spy and the claims may have been right.
