The River Danube is home to a fish that grows larger than the Great White Shark. Although it leads a secretive life, the Beluga Sturgeon – the King of the Danube – produces the most prized food in the whole world.

Beluga caviar is traded for up to 20,000 dollars per kilogramme. Ironically, the high price of this precious product could save the animals from a premature disappearance from planet earth.
