Jellyfish, or Sea Jellies are made up mostly of water. There are over 200 species within just the class of scyphozoans, the most popular being the saucer shaped Moon Jelly, Aurelia aurita, and all are marine free-swimming medusa.
While these species are not that harmful they can still inflict little amount of sting. A jellyfish's body is made up of two layers, in between is a jellylike substance. Jellyfish posses no distinct head, digestive or structural organs, and all possess Cnidae, which are specially modified stinging cells also called nematocyst.

Just incase you get in contact with the nasty ones, douse stings with vinegar and apply ice for pain. IMMEDIATE medical attention may be required for severe reactions.
Jellyfish feed on small plankton animals that they capture within their tentacles. Freshly hatched and enriched brine shrimp, Artemia, has been the substitute for plankton.
