According to the laser measuring instrument and other tools used by scientists, it can be known that the outer ring diameter of this jellyfish is about 15m, that is to say, the outermost circle is15 times 3. 14, which is about 47m long. However, the length of this jellyfish is very strange, like a thin line like a galaxy, so the actual length of this jellyfish is unknown and further research is needed. According to the latest data, this jellyfish is about 1 19 meters long, but its size can be roughly estimated by using instruments, not its actual size, so it's beyond people's expectations just how long the jellyfish is.
