Jellyfish (Scyphozoa) are delicate, soft-bodied animals. Jellyfish are invertebrates, they have no bones, exoskeleton, or shell to protect them. Instead they use their nematocyst from their tentacles and release a toxin that can be very harmful and need to be treated immediately. When a nematocyst comes in contact with an object it could kill or paralyze its predators. Jellyfish are carnivorous and consume zooplankton and comb jellies. They inhabit aquatic environments, which their bell- shaped body allows them to live in.

The jellyfish have two dominant stages, the polyp stage and the medusa stage. During the polyp stage, they remain rooted to the sea floor and don't move at all. During the medusa stage, the more recognizable form, jellyfish obtain their bell-shape and move by propelling themselves through the water. They are considered a delicacy in some countries.
