Can anyone identify this?

Found this little critter in some live rock I recently picked up. Anyone know what it is?

Hi. Welcome aboard! That is a bristleworm. Good member of your clean up crew, but they sting! Don't touch them!

Cool! Thanks for your help!

I don`t like them, because I don`t like that there would be something that could sting me... So I killed off all of them...
