Haha, you may have to go further than Neptune for Sharks, but yeah, it would be pretty cool. I reckon for other lifeforms like the ones we find on Earth, you'll have to look at planets in the goldilocks zone of several star systems. But hopefully within our lifetime we will find some kind of single cell life within our solar system, that would be cool (if a bit unlikely).

I hope its a hybrid of an octopus and goat.

That would be awesome.

Oh and it should be able fly.

The best place for life in this solar system (outside of Earth) would be under Europa. I can only hope we go there in my lifetime.

There are two probes scheduled for 2020 JEO (Jupiter Europa orbiter) and JGO (Jupiter Ganymede orbiter), they should be operational around the moons by 2026, so the likelihood is that we will travel to Europa within your lifetime. I personally think that the moons Enceladus and Titan also have an outside shot at harbouring life too.

Pft.... and people thought that crashing that satellite in there was going to be a waste of money.

Lizard or Spider?  Try bacteria.

Wasn't there something like that a long time ago people claimed was from an asteroid?  Guess that was debunked/unproveable.

It'd be awesome if there are prokaryotes in the water

Or bacteria or some shit...anything!

I disagree.

The animals will evolve differently, but I think will end up "similarish".  Liquid will still be liquid.  Air will still be air and land will still be land despite how different it may be enviroment wise.

Just how all planets are round I believe that there are certain "truths" about which kinds of "parts" work best and what numbers are preferable for different niches.

You couldn't call stuff lizards or spiders outright... but i'd say anything we'd find would well fall into a childs imagination.

The truth is no-one knows.

I would honestly imagine though that through the process of evolution, different life forms would find evolutionary solutions based on their environment. So for life to bear resemblance to Earth then it would need to have a similar environment to Earth. As we know, there are no other planets similar to Earth within our solar system, so for extra terrestrial life to be similar to ours we would have to look outside of our solar system. Where we are looking for life within our solar system (Titan, Europa, etc...), they all have underground oceans and hydrocarbon lakes, etc... Environments which vary greatly from Earths.

But as I said, we may not find out for decades. That's just what I think.
