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 first 15 segments of this worm are translucent but appear bright red or purplish-red, depending on the degree of oxygenation of the blood; the remaining segments appear dark green or black, because of pigments in the gut cells. 33: 288:; digging is performed by the head using the parapodial cirri attached to the first segment and associated long bristles. A water current is drawn through the tube by undulations of the body and fan-like movements of the parapodia and 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 236:
