Russia doubles number of combat dolphins, expands security measures around Crimea

Russia has doubled the number of pens containing trained dolphins near the Black Sea port of Sevastopol to protect its naval forces.
Russia has doubled the number of specially trained dolphins deployed to protect its Black Sea Fleet and annexed Crimea from Ukrainian attacks.
The dolphins are part of a complex multi-layer defense that includes nets, floating barriers, anti-ship missiles, specialist artillery and S-300/S-400 long-range air defenses.
British military spies suspect Russia is training combat dolphins in the annexed Crimean peninsula to counter Ukrainian forces.
Imagery shows a near doubling of floating mammal pens in the harbor which highly likely contain bottle-nosed dolphins.
