The next seven segments have spiny chaetae, and the remainder of the segments from segment 17 onwards bear chaetae that are large, feather-like bristles.

The worm can turn around in its tube, and then the current direction is reversed. The worm probably feeds on plankton and organic particles removed from the water current, and
