Locals spotted a white whale near Popov island. Presumably, it was one of the prisoners of the former whale prison in Srednaya Bay. 

According to «Vesti: Primorye» the dolphin swam up to the boat with people and circled for a few minutes near the boat, allowing to see himself in all his glory. 

The mark from the satellite tag is clearly distinguishable on the body from the satellite tag and therefore the authors of the video assume that this is one of the individuals released in 2019 from Srednaya Bay.
