A total of 11 species of jellyfish, some brought in at the price of 12,000 yuan ($1,900), are on display at the Jellyfish Exhibition Hall that first opened to the public Sunday. Newly-bred jellyfish, primarily for display in hotels or spa centers, are likely to see a major price cut to fit into the pet market in China, according to an unnamed insider of the marine world.
