Bristle Worm...or something else??

[emcmilla]

Found this in my LS after a 9.5 hour move across the province. Looks like a bristle worm, but kinda different.
Distinguishing features:
- earthworm appearance on one side
- bristles on the other but the bristles are only visible if he is flipped over

Any help would be great!

Thanks!

Looks like a species of bristleworm to me.

I found one like that yesterday. It's a bristleworm species.
