and the some possible breathing atmospheres.. GREAT IDEA! How about Methane?
with those nice Carbon and Hydrogen molecules, say an alien's metabolism
takes a whole bunch of methane molecules, makes them into carbohydrates
(read: food) and breathes out excess hydrogen? no smoking around these guys!
how about body chemistry and metabolism? that may be a bit much but one
could always generalize. Should we stick to carbon-based lifeforms?
Asimov's story "The Talking Stone" about a silicon based lifeform got me
interested in sci-fi to start with.
