The dolphins and sea lions trained by the Ukrainian navy in Crimea for military operations are now in the hands of the Russian navy following the peninsula’s absorption by Russia. The Ukrainian navy resumed the program, which was scrapped just before the collapse of the Soviet Union, in 2012 at one of the two aquariums in the Crimean port city of Sevastopol, which is home to Russia’s Black Sea Fleet. The centre worked on developing new methods of training dolphins and sea lions so they could be used to locate underwater weapons and divers.
