Does anything actually eat jellyfish ?
Humans do: Sliced and marinated jellyfish bells (often known as sesame jellyfish or jellyfish salad) is a common appetizer in Chinese cuisine. It is usually made using sesame seeds, sesame oil and, occasionally, spring onion. A similar dish appears in Vietnam, with red chilli pepper added. Korean version of the dish, haepari naengchae (cold jellyfish salad), is a summertime delicacy in the country, and is usually served with sweet and sour seasoning with mustard. Packages of jellyfish bells (Chinese: 海蜇; pinyin: hǎizhé) can be bought at chinese grocery store in a salted and semi-desiccated form, which is usually yellow or slightly brownish in colour. The salted jellyfish does not have any fishy or unpleasant odours. It has been compared to the texture of elastic bands if dried.
