Is it possible that dark matter is as diverse as visible matter?

Certainly visible matter is quite varied, allowing it to form great structures (planets, stars) and great complexity (such a life on Earth). Is it possible that this sort of variety also exists non-visibly via dark matter?

I suspect this is not the case since (as I understand it) dark matter is not suppose to interact with the electromagnetic force, and EM plays an obvious role in the visible variety that we're familiar with. Then again, with so little being known about dark matter (we only have dark matter *candidates*) maybe it's impossible to even speculate an answer. Or maybe I have some fundamental misunderstanding about how dark matter and visible matter interact, and it doesn't make sense to dichotomize the universe as "visible" and "dark."

Either way, I'd appreciate hearing from someone familiar with the topic. Thanks in advance!

Dark matter doesn't interact with each other any more than with regular matter, or else it wouldn't explain all the observations, so there is no sort of dark chemistry going on. Regular chemistry is entirely based on EM interactions. There a few theories that postulate the existence of more than one type of dark matter, like two or more WIMPs, but that's probably not what you mean.
