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.

Jellyfish are eaten by squid. I believe that this is the biggest threat that they face.
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 naruma jellyfish. It has been discovered in November 2009.
No the lion's mane is.

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).
Believe it or not, but the jellyfish is actually the biggest type of Plankton. No, not the evil mad scientist who wants the Krabby Patty formula. ;)
It takes about an hour for a jellyfish to digest a "meal".
Yes it can, as long as it is alive.

the name is the lionsmane jellyfish.:)lion's mane is the biggest jellyfishThe arctic lions mane. But I have heard that one species can have a diameter of eight feet around and the tentacles can be the size of half of a football field. It may be that kind.
A large box jellyfish or a man of war jellyfish could if it had very long tentacles.
