An Animal That Lives Without Oxygen
Julie188 writes "Scientists have found the first multicellular animals that apparently live entirely without oxygen. The creatures reside deep in one of the harshest environments on earth: the Mediterranean Ocean's L'Atalante basin, which contains salt brine so dense that it doesn't mix with the oxygen-containing waters above."
I find it odd that the article mentions absolutely NOTHING about the implications of this discovery as it pertains to life on other planets.

Sorry, couldn't help me self.
Come the revolution, the Bourgeois, Capitalistic, "A PARKING STICKER HOLDERS", will be first against the wall!
Since these animals live underwater, this means they must also have found water without oxygen!
There is no Mediterranean Ocean. There is however a Mediterranean Sea.
Given that there are plenty of bacteria that can do this (including those that find oxygen toxic) it's not surprising that multicellular creatures have evolved to take advantage of low oxygen environments. There are probably numerous, people just haven't been looking hard enough. Plus, when you store your samples in places with air, you get serious sampling bias for things that like air.
Anaerobic respiration does precisely that and has been doing so for generations.
To think that all life needs oxygen or even a sun to exist goes back to our belief that the earth is the center of the universe.In reality we are a blip on the map.
The summary discusses an article which is talking about an abstract of the provisional paper available at http://www.biomedcentral.com/content/pdf/1741-7007-8-30.pdf .
Even David Attenborough who himself narrated the Blue Planet were animals were shown that lived independent of the sun, narrated happily on Planet Earth that all lives needs the sun... It is just that for us it is so true that we forget that it isn't.

"I am certain that these organisms contain oxygen in some of their molecules, like DNA, RNA, amino acids, etc."
Why?
FTA:
" The creature's cells apparently lack mitochondria, the organelles that use oxygen to power a cell. Instead they are rich in what seem to be hydrogenosomes, organelles that can do a similar job in anaerobic (or oxygen free) environments."
Someday, there will be a way to link to articles, and on that day you can stop looking like a duuf.
The Kruger Dunning explains most post on
There are vast deposits of salt beneath the Mediterranean, so much so that it's been suggested (Miracle Planet episode x(?)) that the salt deposits were necessary to the evolution of life forms today because of the amount of salt taken from the seas. Sorry I've not the time to search more but this The Mediterranean Disaster Mystery link gives an intro.

mschaffer refers to oxygen in the sense of the atomic species. It is certain that all known life forms have oxygen atoms in them, and mschaffer is simply being pedantic.
There is no such thing as "Mediterranean Ocean"
He means in the sense that they almost certainly have some water in them, which usually has some oxygen as a component.
Nerd rage is the funniest rage.
You were wrong before you started.
You shouldn't assume that just because life we've found on Earth has anything like DNA, RNA and amino acids.
It is entirely possible that life elsewhere, even on our own planet, can look entirely unlike anything we've ever seen.
Contrary to what many scientists seem to think or at least project, we do not know everything. In the grand scheme of things, we know very very little about the way stuff works in general, even if from our perspective it seems we know a great deal. We barely understand a tiny fraction of the way the universe works on the confines of our own planet, let alone every where else in the universe.
Assumptions do nothing but hold you back. If you can't prove it, don't assume it.

intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
then -> than
percentiles -> percent
I'd guess that, roughly, more than 90% of the human population has a higher IQ than you do.
Suggestion: Make the changes in your "stock phrase" document, then next time you copy-and-paste them into the forum, you won't look like as much of a dunce. You'll still be a moron, just that, it won't seep out of your fingers as obviously.
Only I can judge you.
How do you kill that which has no life?!
Zombies also live without oxygen, when is someone going to release a research paper on that?
"Pedantic," eh? Is that what some of us mean when we say "correct?"
"The creatures reside deep in one of the harshest environments on earth: the Mediterranean Ocean's L'Atalante basin"
We don't have a Mediterranean Ocean here on Earth.

Begs the question, is this an evolved form of some other oxygen-using Earth native? Or does it share absolutely NO ancestors with any other form on Earth? The latter is strong evidence for life as we don't know it elsewhere in the cosmos. A pretty strong hint, iow, that life is cheap and ubiquitous.

Perhaps this little guy does live on oxygen, but simply has a process to separate from the hydrogen directly from the water itself. Just because there is no saturated oxygen dissolved in the water doesn't mean it doesn't live on oxygen.
I read Slashdot for the headlines, because the headlines, unlike the articles, are usually original and never duplicated
@ BitZtream
You are a stupid ignorant jackass! At least I know what I am talking about.
The article mentions that the organism takes up leucine, and amino acid that does indeed contain oxygen. The orgamism lives in brine (you know---salty water). All water contains oxygen. (Ever hear of H2O? It's water---and is is composed of one oxygen atom per two hydrogen atoms.)
Now, if someone had discovered an organism on earth that doesn't use oxygen in some part of their respiration, DNA, RNA, and amino acids, maybe, just maybe, that would justify your dumb-ass existance.
Just to be clear, I do mean organism. Prions and the like are not necessarily organisms.
