Russia is reportedly using trained dolphins to protect a Black Sea Kremlin naval base, according to a naval analyst.
Satellite images could prove the marine mammals are being used as two water pens have been spotted at the entrance to Sevastopol harbor in Crimea — which Russian forces annexed from Ukraine in 2014.
According to submarine analyst H I Sutton, the pens were moved there in February - around the time Russia began its invasion of Ukraine.
