This may be the most random topic, but i have a few interesting facts. The largest Jellyfish is longer than two school buses parked end to end. The smallest jellyfish could fit on a contact lense. Jellyfish are 95% water, and have bone, brain, or heart. However, they do have a nerve web. The most dangerous type of jellyfish is the box jellyfish. Box Jellyfish venom is potent enough to kill an adult male in 10 minutes. Some Beaches in Australia have boxed-off sections so swimmers can swim safe from box jellyfish. Some jellyfish glow.

Luckily for me, I've never personally encountered jellyfish while at beaches and the sort. It would, however, be nice to see a jellyfish up close and not get stung by it.
Technically, a polyp is not a plant, but does act like one. There are, by the way, some jellyfish that don't sting. They have lost the ability and need to sting over centuries of having as much food as they need and no predators. They live in shletered lakes in tropical islands near africa.
Not to spoil anything but this might get locked because it seems like those copy, paste threads. Anyways I've seen a jellyfish up close. I touched the top of it and it seemes like really soft jelly.
On-topic; Jellyfish have been around for more than 650 million years which means they outdate both dinosaurs and sharks. Or so I have been told by google.
Wait... The first definite multi-cellular organisms were found on earth 540 million years ago. Somehow that fact does not fit with what you have been telling us.
Sharks have been here since around the Devonian, which is 350 million years ago, and the first dinosaur like creatures were around 250 years ago. I do know jellyfish were found a bit after (-or before- the Cambrian... Which was mostly around 500 million-ish years ago... So yeah, they out-date dinos and sharks by a lot.)
(Please do consider the fact I said AROUND ... years. My data may well be false...)
