I guess you meant Aqua Regia? Not at all well versed in biology, but that seems less of a challenge than the other materials proposed (heavy metals, etc). Aqua Regia is a mixture of Nitric Acid and Hydrochloric Acid. At least the first seems easy enough to digest and obtain energy from. Yes, it is very acidic (ph 0 - 1) but so is your stomache (ph 1.5 - 3.5) and plenty of bacteria survive in that. Couldn't find a specific species on google though =) |

ph is a logarithmic scale so the difference between ph ~0 and ph 3 is of 3 orders of magnitude (or something like that. My maths is rubbish...). it can dissolve noble metals so I doubt anything living can survive it. But once diluted, some extremophiles may be live off it. while googling found this interesting article

so yeah, the challenge is halfway broken. science is amazing. :D
