Another ID (large pic)

[Stretch]

Last night after the lights went out it, Was looking around and saw these.

I have never seen these before in person or photos. They were attracted to the light of the flashlight like a moth to light and would follow the light around.
Now these thing could swim very quickly, they have the appearance of a bristleworm crossed witha maget is my best description
they had 4 black dots on their head, the eyes i suppose.
