Worm ID

[muck]

I was watching a little "worm" type thing on my glass yesterday night. It was about an inch and a half long. Looked sort of like a bristle worm, but one end got thinner like it was the tail. It was gorging itself on the green algae growing on the glass. I couldn't believe how fast and how much algae the thing ate. It was light brown almost a little opaque. (You could see the algae inside it after it ate) The thing was also pretty fast moving and moved more like a centipede then a worm. Anyone know what it is?? Unfortunately I left my camera at work and couldn't take a picture.

Anyone have any good links to hopefully identify this and other different types of worms.
Im sure some of you have pages and pages of bookmarked material.


TIA!
