Atmospheric Jellyfish are jellyfish that made their first appearance in The Swarm At The Edge Of Space.
These creatures are lighter than air and made of substance called star jelly. They has ability to shape shift themselves in a limited way, such as combining into one creature, but also can change their color. Zak uses them as soldiers in "War of the Cryptids". These creatures have very unstable molecule compositions. This means that they have the free ability to manipulate their bodies in any way. These creatures have been known to attack humans, but not target them as a food source. When disturbed, they will attack any life form that threatens them.
