Their idea of "fresh air", then, is a place with lots of dissolved metals like iron or manganese, or even uranium or plutonium. The species respond to a chemical signal only when the concentration of the molecule reaches a specific level. A very unique and specific breed of bacteria also lives in hair gel and hairspray.
