Can organisms thrive in scalding water?
It depends what temperature region is being considered. To take the human example, not only superficially would we be burnt, but the raised temperature over a sustained period of time will result in irreversible enzyme damage. This, in most organisms (i.e. a pathogen) is why they are unable to survive at the enzyme damage sustained results in complete malfunction. Potentially, there are organisms with can survive in very hot water as they have evolved that way. Species living on or near deep ocean vents are exposed to extreme conditions by survive due to millions of years of evolution, but to answer the question, most organisms in most taxa cannot survive.
