Could there be organisms made out of dark matter?

It's possible. The most generic dark matter candidate is a WIMP (weakly interacting massive particle), and it is pretty unlikely an organism could be made out of WIMPs, since that are so weakly interacting that they just pass through each other. However there are other dark matter candidates, such as CHAMPS (charged massive particles) that maybe organisms could be made out of, and more generally there could be whole "dark sectors" with dark "atoms" and many dark particles with complex dynamics between them that could support life. This kind of dark matter probably doesn't make up very much of dark matter though, since there are various pieces of evidence (such as the shape of the galactic dark matter halo, or the shape of collisions between galaxy clusters) that seem to indicate that dark matter doesn't strongly self-interact.
