Floaters resemble floating jellyfish, with a translucent body and tentacles. They are a highly telepathic race, one of the most telepathic races in the galaxy. They commune with each other telepathically. They are also quite intellectual, and avoid physical conflict when possible. They are delicate, and not particularly adept at defending themselves physically.
Floaters are used to very low or no gravity. They dwell in the upper atmosphere of worlds. Floaters colonize worlds without spaceships somehow, suggesting they can travel in space and somehow travel across interstellar distances.
