How Many Jellyfish Are There in the Black Sea?

The Black Sea, an inland sea located between Asia and Europe, is often referred to as the jellyfish capital of the world because there are an estimated 1 billion tons (907 billion kg) of jellyfish living in its waters. At one point in the 1990s, the Black Sea contained the equivalent of more than 10 times the weight of all of the fish caught in the world each year. Jellyfish are not native to the Black Sea and are thought to have been inadvertently introduced there by a ship in 1982. After the introduction of the jellyfish into the Black Sea, the supply of fish that are caught for food — such as mackerel, anchovies and sturgeon — declined rapidly in the surrounding areas and affected the economies of countries such as Romania and Georgia.

More about jellyfish:

  • Jellyfish are able to double in size each day by eating 10 times their body weight in food.

  • The Chinese have been eating jellyfish for at least 1,700 years, according to ancient texts.

  • The jellyfish is thought to have appeared three times as many years ago as the first dinosaurs.

@Viranty - Going off of what you said, I wonder how the jellyfish are prepared by the Chinese, which would be very unusual, to say the least. Who has ever heard of people eating jellyfish. Are they boiled, baked, fried? Who knows really?

The second bullet point is definitely what caught my attention the most, especially where it (indirectly) mentions that the Chinese eat jellyfish on a daily basis. One reason why I find that so interesting is that prior to reading the article, I hadn't known that.

Considering how jellyfish are able to eat so much, it really makes me wonder how they even manage to eat in the first place. For example, where is their mouth? I'm going to assume that they use to stingers to paralyze their prey, and then attempt to bring it inside of them?
