If anyone is interested in “what could alien life look like?”, I can highly recommend reading the Children Of Time trilogy by Adrian Tchaikovsky.

He manages to really have his alien species feel like truely something non-human.

Reading the novels feels like going on an adventure

I’ve always wondered how much alien life is out there that we’ve actually seen (or seen signs of) but not recognized because we’re blind to life that doesn’t seem earth-like.

To not quote tha author is a crime.

Shame on you, OP.
