Although it may seem like science fiction, Russian dolphins are capable of placing a device on a diver to ensure that a buoy deploys after a few minutes and brings him to the surface in full view of his enemies.
This is what could happen if the Ukrainian military sends divers into Sevastopol Bay, where HI Sutton, an expert submarine and defense analyst, has discovered pens containing Russian army dolphins.
Satellite photos show that the animals arrived at Russia's largest Black Sea naval base in February.
What exactly do these mammals do?
What other armies have animal units?
Since when have dolphins been trained for military use?
In addition, the video shows how Turkish researchers have detected stranded and dead dolphins in the Black Sea in recent months.
Some of them show clear signs of entanglement in fishing nets, but for others it is difficult to know the reasons for their deaths.
Experts say that noise pollution from ships and military activities are very harmful to these animals.
