Mynock
a species of winged parasite that was composed of silicon, mynocks roamed the vacuum of space in search of their favorite food: pure energy. They most often were found in the vicinity of an asteroid belt, where they could find a suitable asteroid to feed on, ingesting silicon and other materials until it was time to reproduce. Mynock reproduction was based on fission of a single mynock into two new mynocks. Their origins were unknown, but it was known that they could not fly through hyperspace by themselves. This caused many xenobiologists to assume that mynocks had a single origination system. They could grow to lengths of 1.6 meters before reproducing. Because mynocks fed on energy, they often attached themselves to passing ships, chewing holes in conduits from which they could draw the energy they need to survive. Note that Lando Calrissian and the Mindharp of Sharu indicates that mynocks could reproduce in an atmosphere, just before dying.
