Like many other marine life, the worms use gills to breathe oxygen through water. It’s not hard to break it down; most simple acids will do the job. A clam whose shells have been re-engineered as drill heads also has dozens of mini-teeth that scrape rocks for food, ingesting and breaking them down. The bacteria use the hydrogen sulfide as energy to produce organic carbons that feed the shipworms. And yet Kuphus eat very little.
