The local wildlife on Bespin, despite being a gas planet, include the rawwks, a flying mynock-like bird, as well as airborne algae sacks. Among these are the beldons, the velkers, the glowers and the pinks. The skies are also home to a number of transplanted life forms, such as Alderaanian thrantas
The planet itself is formed like most gas giants, with a solid metal core, a liquid sea of metallic rethen as well as non-metalic rethen, followed by a habitable layer of gas. Anything below the layer of gas would however, collapse under intense pressure. However even the life zone, where mining is possible has its hazards, as there are frequent ice storms that are built up from the surface.
