Imagining creatures which dwelled on atmosphere of gas giants like jupiter and other exoplanets. These creatures may be dwelling on upper atmosphere of such gas giants like Jupiter and saturn. Unlike innerterrestrial planets such gas giants are primarily made up of atmospheric gases with enormous pressure due to their high gravitational pull. Since the upper atmosphere of jupiter is more friendly to evolve life with complex organic molecules. They may have had enough time to evolve some type of ecology, may be an aerial form of life. To determine how scientifically plausible such ecologies Might be ? A paper titled Particles, Environments and possible Ecologies in the Jovian Atmosphere published by Carl Sagan , represent such cases. The creatures which are assumed to evolve in these worlds are sinkers, floaters and hunter(predators are referred as hunter). The sinkers are small organisms ,constantly falling towards deep,dense and comparatively hot layers of atmosphere. These creatures manage to survive long enough to produce offspring that would stay up in more habitable environment to regenerate its copy. The second are floaters which are enormously large, more than thousands of times larger than any dinosaur or great blue whale that ever lived on planet earth , makes it kilometers across about the size of a city. Floatess were seen as drifting across the giant alien sky. How they float in sky? Simply they may have had hydrogen gas storage which is essential part of jupiter. The third are predators generally referred as hunters which preys floaters for their organic molecules and hydrogen storage. These hunter are supposed to be fast enough to prey.
