There is no one length to a jellyfish! But there is quite a range. I was on a junk (motor boat) the other day and I came across three jellyfish; One about 30cm long, one about 15cm long and one about 7cm long. The biggest jellyfish is bigger that the average man and the smallest is about the size of your pinkies finger nail!
The lion's mane jellyfish, Cyanea capillata, was long-cited as the largest jellyfish, and arguably the longest animal in the world, with fine, thread-like tentacles that may extend up to 36.5 meters (120 ft) long.
The smallest jellyfish are the peculiar creeping jellyfish in the genera Staurocladia and Eleutheria, which have bell disks from 0.5 mm to a few mm diameter.
The largest jellyfish ever recorded was an Arctic Giant that was washed up in Massachusetts Bay, USA in 1870 which had a bell diameter of 2.28m (7 ft 6 in) and tentacles stretching 36.5 m (120 ft).
