A vulcano-living rust monster?

Not really but scientists have found a microbe in the volcanic vent of the Pacific Ocean and it can multiply and survive in 121ºC (249,8F). That's a new heatrecord for a living organism to survive in (even though some Finnish hardcore-sauna-fanatics would strive to say that they bathed saunas hotter than this).

But Finnish don't live from iron. This micro-organism does. Luckily it dwells only on the bottom of the Pac Ocean and ain't big enough to eat a Volvo.
