Of course they have a purpose! They are part of an ecosystem. Without them, everything would be messed up. They eat other jellyfish and zooplankton. Swordfish, tuna, and sharks eat them. Even sea turtles. And they are very cool. There is research underway studying how they survive without brains.

A little more than a year, normally. They congregate annually for dispersal spawning, and adults die soon after spawning.

Usually, the common jellyfish would live up to a year or 2. Some live up to 5 years and other specific types may live up to 30 years. There is one type of jellyfish that can technically live forever, because it reverts back to the polypoid stage when it has matured enough.

not commenly however when i was there i was stung by a 3 foot Portuguese man o war (we think) resulting in me spending a day in hopital. the beach staff were really helpful and did all they could, the said it was the worst sting ever on the beach. however my case is extremely rare and i would not put off a trip there, as the surf is amazing and i had a great time.

First off, all three types of organims are in the kingdom Animalia, and are not plants, they are animals. Jellyfish and Coral are both in the phylum cnidaria; jellyfish are further divided into class Medusozoa, which has a number of its own subgroups, whereas corals are in the class Anthozoa, which again is subdivided into a number of its own groups, but the what are usually considered corals are mostly in the groups Scleractinia(stony corals) and Octocorallia(soft corals, gorgonians, etc). The sponges on the otherhand are in a completely different phylum, Porifera, which is further divided into many different groups, and is not closely related to the Cnidarians.

The largest Arctic jellyfish (and the largest known species, period) is known as the "lion's mane jellyfish."
