In recent months, an impressive number of dead dolphins have washed up on the shores of the Black Sea. Scientists say the animals are being hunted by Russian warships and the “noise of war” from Ukraine.

More than 80 dolphins have washed up on Turkish beaches since the start of the war in Ukraine, according to the Turkish Maritime Research Foundation (TUDAV). The research institute calls this “extraordinary”.

More stranded dolphins have also been found on the Bulgarian coast. Many mammals show no injuries, so it is not immediately clear why they fail so massively.

One possible explanation, according to Turkish, Ukrainian and Bulgarian researchers, is that dolphins are driven out of the Black Sea by Russian warships there. Researchers speak of “acoustic trauma” in animals.

Additionally, the “sound of war” heard underwater would deter the animals and force them to swim south. This can disorient them, causing them to run aground more quickly. In addition, dolphins become entangled in fishing nets in greater numbers, causing them to drown.
