Worm ID

This one is from a dive on Sunday near the Inner Tubes, Jervis Bay, Australia.

Matt took this photo of a worm and we are wondering what it is.

Hooray! It's one of mine There's been a bit of a drought lately.

Yes, this would be a nemertean; possibly a color variant of Notospermus geniculatus, which normally is a variety of green with white annuli. But it could be something altogether different and I would have to be able to see the head to know.

which end would that be ? (in the photo )

BTW, I'd love to be finding more too

It looks like the head is on left. My non-scientifically studied impression is that many of these relatively long nemerteans forage from hiding places, such as crevices, by exploring as far as they can with the head but leaving the tail end in the crevice in case the worm has to make a speedy retreat. In fact, if you can snag one of these worms it's kind of like pulling taffy, but it often is very difficult to get the back end out of its purchase.

Lucky I asked then ... I thought it was on the right
