Jellyfish are creatures that belong to the Scyphozoan class, which is part of the phylum Cnidaria. The body of an adult jellyfish is composed of a bell-shaped, jelly-producing substance enclosing its internal structure. From this, the creature's tentacles are suspended. Each tentacle is covered with stinging cells, known as cnidocytes, which can sting or kill other animals. These are mainly used to secure prey or as a defense mechanism. However, some jellyfish species do not have tentacles at all, such as Rhizostomae.
Despite their lack of basic sensory organs and a brain, jellyfish have an efficient nervous system and rhopalia that enable them to perceive stimuli like light or odor and respond accordingly. In their adult form, jellyfish are composed of 94-98% water and can be found in every ocean in the world. Most jellyfish are passive drifters that feed on small fish and zooplankton caught in their tentacles. Jellyfish have an incomplete digestive system, meaning they use the same orifice for both food intake and waste expulsion. They are made up of three layers: epidermis, gastrodermis, and mesoglea, a thick layer that produces the jelly and separates the epidermis from the gastrodermis.
