Damn you extinctions

      I do think some of the suppositions that people make about the chemistry and basic structure of alien life are pretty convincing. Like any complex life form is probably going to have lots of liquid bits surrounded by solid linings, with lots of complicated carbon-based compounds throughout, simply because that's pretty much the only way you can get complicated chemical things to happen. Water is a good bet for being the main liquid component because it's extremely common and is a good solvent, though something like ammonia is also plausible.

      Beyond that I think it's hard to be sure of anything. All kinds of strange body shapes could make sense on a world with different gravity, different geological formations and different plant life from ours. To be fair, a big reason why a lot of sci-fi sticks with aliens that are roughly the same size and shape as humans is because it makes storytelling easier, not to mention costumes/animation.
