Seems like an interesting issue for evolution: "I don't have any use for oxygen, but my progeny will die without it."

I'm having a hard time seeing how this would evolve via incremental steps.

Not a good pick-up line.

That depends on the bar... And the hour...

ability to survive without oxygen

nothing new...

[James C. Bennett]

Simultaneously having multiple energy cycles, would be evolutionarily beneficial. It could have started out that way.

"animals have been discovered that live their entire lives without oxygen and surrounded by 'poisonous' sulphides"

Big deal - George Soros has been doing it for years and thriving.

Oxides in their food sources, used by a special breakdown process?

Dunno. It says that they live their entire lives without oxygen but I don't know if that's to be taken literally.

	Gods Graves Glyphs	Carebears? Teddy Ruxpin? Thanks decimon!. Deep under the Mediterranean Sea small animals have been discovered that live their entire lives without oxygen and surrounded by 'poisonous' sulphides. Researchers writing in the open access journal BMC Biology report the existence of multicellular organisms (new members of the group Loricifera), showing that they are alive, metabolically active, and apparently reproducing in spite of a complete absence of oxygen.

Try this:
Several unicellular organisms (prokaryotes and protozoa) can live under permanently anoxic conditions.

More possibilities....now to check Mars.

Can’t be literal.

Unless they have no DNA and are like those rock things on Star Trek.

De-OXY-ribonucleic acid.

So they must mean they actually have oxygen in them, but for them it’s more like a mineral. Like calcium is for us.

But their respiration is based on H2S.

Well...that sounds good.
