How would you speculate organisms would look on distant and alien worlds?
And before anyone says anything, no I don't want to ask /x/ because of the genuine loons there.
One time I came up with a parallel earth of sorts where hallucigenia descendants took over. There were balloon-like flyers, and plesiosaur-like swimmers, not to mention the many forms of land-dwellers.
There was also this gas giant where the "flying rod" bauplan evolved naturally.
What's always weird to me is that scientists use water as a method of deciding if a place can have life. But what if it's different on another planet? What if like, everything ran on sodium?
