No.

Elemental H2O(l) is not the same as O2(g), just because the presence of elemental oxygen does in no way mean that such an environment is aerobic. Fish do need O2, it's just disolved O2(g) in H20(l) and gills are the extractor -counter gradient. The oxygen in H2O is more of an electron donator/acceptor in the electron transport chain used in all organisms that generate ATP.

I have grown anaerobic bacteria in a culture lab and submerging the sample in H2O is a frequent technique used in place of a vacuum.

Thats because fish breathe oxygen that is trapped in the water surrounding them. if there were any aerobic organisms in this lake they would've used up all the oxygen long ago.

Not sure, they said the lake was black?

I will need to read this full article when I get home.

i would accep the idea of Opening up a Pathway to a Hidden Pyramid which contains scores of Aliens for which the Predator's Noobies do battle with, before I would believe some Flehs Eating Bacteria could be involved

I would be more afraid of such a virus similar to rabies. But like with all isolated environments, without an ample host supply -resistant to death en masse, the possibility of such devastating virus is nil. More likely is some variant of archaebacteria that probably forms a tight knit symbiosis of whatever is down there.

I think he was sarcastic.

You can get flesh eating virus from aerobics? Another reason to stay away from those leotards doings aerobics, dont you know your risking your very flesh.

And how can a lake be below freezing, but its not frozen, quit the paradox, and life as we know it requires liquid water, so many questions. Maybe it some sort of energy field creating a zone where paradoxes can exist. Some sort of... ancient alien technology.

The absurdity of it all.............

Its Seven times saltier than the ocean. Salt reduces the freezing point of water.

Actually, many kinds of bacteria responsible for necrotizing fasciitis are facultative anaerobic or anaerobic.

Water does not automatically imply significant dissolved oxygen.

There are bodies of water that have such a low disolved oxygen content that aerobic respiration won't work, and thusly lack fish.
