Are bristle worms A-sexual?

[125intx]

Just wondering? How do they spawn? Eggs? Live born? I was watching Fat Bast**d in my nano, he is a good 18" long. and wondering what the longest/biggest bristle worm you have seen is.

Bristle worms have a wide variety of reproductive methods depending on the species.
