Muscle Maggot
this burrowing insect was native to the planet Rattatak. They were named for the way in which the consumed only the muscle tissue of a host organism, a trait that the native Rattataki put to use as an interrogation technique. A few muscle maggots were placed on the skin of a prisoner and allowed to begin burrowing. Over time, the prisoner lost muscle and strength, making them more susceptible to questioning.
