Worm ID Request with Pictures

[GroktheCube]

I'm in the process of removing my sandbed, and found this guy while rummaging through the sand I removed looking for anyone that got stranded. He's 5-6" long when fully extended. I THINK it's a Nereid, but I'm not positive. I managed to get a picture of his jaws, which might make things easier. Total number of tentacles is 8 (that I can see). 2 larger pairs projecting forwards, the pair on top longer than the pair on bottom. 2 smaller pairs projecting outwards from the side of the head, 1 small, and 1 very small.

Found him after some searching:

Nereis latescens, or at least genus Neries. The face pattern on mine looks slightly different.

That is a FREAKY worm. It looks like something that would be on an alien planet, attacking people... Especially those jaws. I bet it would hurt if it bit you!
