Brief introduction of jellyfish in Qian Yue

Neopilema nomurai is a giant jellyfish with a diameter of over 1 m. When it is fully grown, its diameter can reach 2 meters, and some individuals even reach 2-3 meters and weigh 220 kilograms. It can be compared with another giant jellyfish in the United States, the lion mane jellyfish (with the longest tentacles), and it is one of the largest jellyfish in the world. Early-maturing jellyfish first appeared in the Yellow Sea and the East China Sea, but due to various problems such as global warming and marine pollution, they also appeared in the Sea of Japan from the1960s, and their numbers are still increasing.
