what are atmospheric jellyfish?
An atmospheric jellyfish refers to cryptids that allegedly reside in the earth’s atmosphere. They are also known as atmospheric beasts. Some researchers considered them as living creatures. However, they seem to go against the scientific laws that apply to living creatures.
According to research, these creatures are soft bodied and can fly on their own. In addition to this, there are part of the jellyfish that are cannot be seen by the naked eye. However, some experts say that they may be an offshoot of some other creatures from other planets within our solar system or within giant gas clouds from outer space. - Jellyfishfacts.net
Carl Sagan proposed, albeit offhandedly, that this kind of creature could live in the atmosphere of a gas giant, such as Jupiter. Illustrations of atmospheric beasts have appeared in books, exhibiting speculation as to the exotic forms extraterrestrial life might take. Descriptions of this sort often portray these beings as living balloons, filled with lighter than air gases. In the context of a Jupiter-like planet with a hydrogen atmosphere, such an organism would have to be a hot hydrogen balloon, since there is no other lighter gas. - Wikipedia.org
