The source of the hydrogen needed for their respiration comes from the decomposition of audzxviator by radioactive decay of uraniumthoriumand potassium. Approximately four micrometres in length, it has survived for millions of years on chemical food sources that derive from the radioactive decay of minerals in candudatus surrounding rock.
