Alien is any non-Earth life. For most people? ... intelligent, non-Earth life.They were alien animals, right? Alien can refer to microbes on Mars or a non-sapient predator or prey that developed and evolved on another planet, right?
Isaac, you might want to take a look at the work of Peter Watts, who is a marine biologist, and Julie Czernada, who was a biologist specializing in insects. Both have made interesting alien races and ideas about animal development. You might also be interested in the Old Man's War books of John Scalzi. Scalzi is not a scientist, but he has come up with some colorful aliens for those novels.
C.J. Cherryh is a good one for aliens also. She was a classics professor but also studied engineering, and NASA named an asteroid after her cause they liked her stuff. David Brin does create some interesting aliens in Uplift. Brin is a physicist, not a biologist, but he came up with some inventive species.
Completely separate from that, you might want to read a non-fiction book called Your Inner Fish by Neil Shubin. The book is a primer in biological development on Earth, going over eyes, hands, etc. and so might give you a basic framework of how bodies operate and change to work from.
Though scientific background can certainly add to and bring about great stories, having a background should absolutely not be necessary for writing great science fiction. I don't know about anyone else here, but I find the task quite simple while still being able to bring about unique ideas and such.
A scientific background is completely irrelevant for writing sf.
This is where we get the difference between
SCIENCE Fiction and Sci-TROPE Fiction
And then there are readers who either cannot recognize or do not care how bad the science in a story really is.
I believe a scientific perspective affects a persons thinking at an early age. Bujold's father was an engineer and she was a pharmacist. Even her stories which do not have much science have a consistency that shows how she thinks.

Someone with an arts background can write a perfectly good hard sf novel. It's all in the research. People with scientific backgrounds are no better and no worse than people without them. The distinction between science and "sci-tropes" exists only in your head.
Rather then make generalisations I tried specifying examples and rating them.

Artificial gravity without rotation is a standard sci-fi trope. Lots of books have it and no one tries to explain it. But we do not know if it is possible. But unlike FTL There is no physics indicating a likely impossibility.

Psik,
I have read Red Nails a few times, why is this being classified as Sci-Fi? Is it because of the magazine it original appeared in? Strange....
#1 is blatantly not science fiction but instead sword and sorcery fantasy.

IOW, if it's not Mundane sf, you don't consider it sf. Which seems to me to miss the point of sf.

Your description of anti-gravity as a trope with "no physics indicating a likely impossibility" sounds like a way to describe Mundane SF to me.
I actually go some way to explaining how artificial gravity works (the non-rotation type) on my blog. So please don't say no one tries to explain it.
