Footage shared on social media in Russia of a polar bear with "T-34" spray-painted in black on its side has alarmed experts.
Experts warned the stunt could affect the animal's ability to blend in with its surroundings and hunt for food.
An investigation is under way to determine exactly where in Arctic Russia the video was filmed.
The T-34 was a tank that played a vital role in the Soviet Union's defeat of Nazi Germany in World War Two.
The footage was posted on Facebook by Sergey Kavry, a member of the World Wildlife Fund (WWF) nature organisation, and then shared by local media.
