Lets imagine what intelligent alien life and the ecosystems thereof on Eve.

[Whirligig Girl]

Imagine DNA found a way of happening deep in Eve's sludge-like oceans, and about the same time as life on Kerbin started up, now Billions of years later, as it did on Kerbin and Earth, intelligent life evolves in on the surface of Eve. What does it look like, how does it differ from Kerbals and Humans, and what other life forms and Ecosystems exist on Eve? I know it's crazy, but that is just the way Kerbal Astrobiologists like it.

Purbles. As in Purple Kerbals.

I'm setting the bar low for the beginning of the thread, I'll come up with something more creative later.

I suppose there would be phototrophs living in the ocean. Perhaps the catalyse the photodissociation of sulfur dioxide and then chemotrophs who then oxidize it again.

I once drawn some aerostat aliens on Eve that mainly lived up in the sky floating around in search of mates and prey, I might reddraw them tomorrow.

[lajoswinkler]

Probably some Yellowstone type stuff, like those bacteria that produce colorful stuff.

Well, if we assume that Eve's oceans are actually water (Eve surface pressure according to the wiki is 5 atm; the boiling point of water at that pressure should be roughly 150 C), then the biochemistry might be fairly similar to Earth hyperthermophiles.

The highest temperature organisms discovered so far are Methanopyrus able to actively live and reproduce at up to 122 C, and Geogemma "Strain 121" at 121 C (though it can survive - inactive, but able to revive if cooled - at slightly higher temperatures).

Well, the devs once mentioned that Eve's oceans are made up of rocket fuel. If it's something like the fuels used in the first stage of the Saturn V, we're effectively talking about a hydrocarbon-based atmosphere and fluid cycle, a la Titan. While Titan has a methane cycle, it's not inconceivable to think that Eve might have a kerosene cycle, with some interesting lifeforms developing out of that.

The problem is that you can't have kerosene before lifeforms. The rocket fuel thing was just a devs' joke.

Perhaps they had lifeform before the kerosene ocean?

Nonsense, there are plenty of natural processes that can produce hydrocarbons. The aforementioned Titan being a prime example.

Possible, but not likely.

On Titan, you have low hydrocarbons and their isomers. Those are the icy leftovers from the initial nebula, and they're present on all gas giants.

Kerosene is an artificial product, but let's say we're talking about petroleum like the one we're mining from the ocean floors, etc. Petroleum is made of medium and heavy hydrocarbon chains. There's all kinds of things inside: from heptane and octane to heavy 60+ chains (tar). There are aromatic hydrocarbons, nitrogen and sulfur compounds. All those things require zooplankton deposits, pressure, temperature and time. There is no petroleum on Titan because nonbiological processes can't make such complex molecules.

Existence of phototrophic lifeforms is dependent on how similar Eve is intended to represent Venus - as in: how dense is the could cover meant to be?

But lifeforms living without light or oxygen are closer even than Venus: http://www.telegraph.co.uk/earth/wildlife/7570677/New-species-lives-without-oxygen.html
