Jellyfish
The Moon jellyfish's scientific name is Aurelia aurita. They are members of the kingdom Animalia, and the phylum Cnidaria(Colenterata). They are free swimming marine animals made up of a gelatinous umbrella- shaped bell and tentacles. Jellyfish do not have a set bone structure like other animals. They have a gelatinous substance to help support them in the water. With out the water the Jellyfish will collapse and die. The outer layer of the bell is made up of epidermis cells. The inner layer is made up of gastrodermis cells. The area in the middle is filled with mesoglea. The Jellyfish has a exoskeleton and a hydrostatic skeleton.
