We went on a Bari Reef night dive tonight. We called the dive after 38 minutes. In the beams of our lights were hundreds of small wiggly worms in the water column. We don't know what they are and were creeped out by them. They were one inch -three inches long, very slender and very wiggly. What are these things?
Ewww, worms!
Although I'm not sure, and hope someone else will be able to answer your question, we have seen the same thing in the cold waters of the Pacific NW certain times of the year. Absolutely creepy! I think they are attracted to your lights, thinking it's the full moon or something.

The closest I can come up
The closest I can come up with are blood worms, but I really don't know.
