Beldon
a huge, floating creature that inhabits the lower atmosphere of the planet Bespin, the beldon is a balloonlike gasbag that consumes the materials that swirl around the outer, molten layers of Bespin's core. Occasionally, the beldons will rise into the upper atmosphere, feeding on the aerial algae and plankton by dropping thin tentacles into the clouds. There are a number of gas prospectors who claim that the beldon gives off tibanna gas as a by-product of digesting rethin, metals and other elements. This was proven only after the Empire's garrison on Cloud City was eliminated in the wake of the Battle of Endor. The management of Cloud City, therfore, made it illegal to hunt beldons. Another unique characteristic of the beldon is that it is surrounded by a low-power electrical field. This field appears to have no purpose, but may have allowed the beldon to sense the approach of danger.
