The harvap, a creature of Nim Drovis (a planet), was non-sentient. After Jarn Harvus found and classified this species, it became common across Hutt Space. Initially, harvaps consumed carrion, but as their numbers grew on industrial planets, they evolved to consume industrial waste and refuse. They thrived in Hutt Space, and the atmosphere of Quesh caused a particularly resilient type of harvap to develop, capable of living in its toxic air. A key adaptation was specialized microbes in their lungs that filtered radioactive gases.
