Floater
this was the name given to any of the various species of creatures which inhabited the upper cloud layers of the planet Yavin. Of the twelve known species of Floaters, two were predatory and fed on the other ten species. One of the predatory species resembled a large, floating jellyfish or squid, while the other - known as a hunter-floater - was sharklike in its form. Herbivorous floaters resembled huge jellyfish, and strained microscopic plantlife from the atmosphere with the stunted tentacles ringing the underside of their bodies. All species ranged in size from 30 to 1,500 meters in length, and were confined to living in a certain layer of Yavin's atmosphere. If removed from their natural habitat layers, floaters literally exploded, as their bodies were unable to adjust to lower pressures.
