While the Spinarran diet is technically omnivorous, they are primarily lithophagous, eating raw rock and metal. The minerals they eat are broken down by specialized chemicals secreted by glands in their mouth. These chemicals can be manually ejected by spinarrans as a defense or mining mechanism, but most of the time remain safely stored away from their oral cavity. This adaption is considered quite useful by interspecies couples.
