This coronal muscle enables the animal to pulsate by its contraction movements, thereby causing it to move. Within these habitats, the degree of contain-ment, tidal flow, water depth, temperature and salinity, and trophic condition can vary quite considerably (Table 1).
In the medusa stage, they move differently by using muscle cells called coronal muscle, present in the bell-shaped upper body.

Hence, they are also often termed as saucer jelly. The polyps use their gastrovascular cavity as a hydrostatic skeleton, and also use few muscle-like cells for contraction and extension movements. These sting cells are their defense mechanism and help in protecting themselves from predators. Aurelia aurita is a pelagic species but may be found washed up on the shore.
The moon jellyfish has a translucent 10 to 16 inch bell with a fringe of short tentacles. Reproduction in them is sexual (distinct male and females), with distinctive bright-colored gonads, visible through the transparent bell body. These canals run into the stomach and bring the food to the stomach via the ring canal, where it is broken down by digestive enzymes.Moon jellyfish contain 4 gonads that are situated at the bottom of the stomach. Jellyfish controls these propulsion with the help of rhopalia centers.
