|Red trumpet calcareous tubeworms, Serpula columbiana. Taken with flash: it's dark down there.|
The worms live in white tubes attached to the rock, curved outward at the head to spread their feeding tentacles. The central circle is a funnel-shaped door, or operculum. It seals the tube when the tide goes out, hiding the brilliant head.
|Zooming in. I like the rayed funnel on the one on the right.|
The spaghetti worms cannot retract their tentacles, as most tentacled worms do. And they really do look like wet spaghetti dumped in the sand, with a sculpted carrot for a body.

The white "spaghetti" are feeding tentacles. Just beneath them, some of the red gills are visible here. The worms build themselves a soft mud tube, but are not always protected by it. In this photo, only the tail of the worm remains in the tube.
|The polychaete worm is not as spectacular as its cousins, but viewed closely, has lovely, shimmery colours, blue, green, pink, and sometimes red.|
