Jovian

Jovians are extraterrestrial beings native to the gas giant Jupiter, the fifth planet of the Sol System. Although not as popular as Martians or Venusians, Jovians are still a fairly common theme in science fiction and astrobiology.

Because the planet is a gas giant, native inhabitants of Jupiter are usually depicted as large floating organisms, similar to jellyfish or living balloons. Rarely are these creatures sapient.
