Dianoga
this unusual mollusk was found throughout the galaxy, living wherever there was sewage for it to subside on. It had seven tentacles and a single eyestalk, and a beaked mouth dominated its underside. The origins of the dianoga have been traced to the planet Vodran, a swampy world where the dianoga has had to develop a tranparent camouflage in order to escape from the planet's large predators. Also called a garbage squid, this species has migrated off the planet, following the scent of garbage to starships and stowing away. They grow to be an average of 5-6 meters in length, although specimens of 10 meters are not unheard of. Their bodies, when unfed, become transparent. They change to reflect the colors of their food once they have eaten.
