Bamboo Worms

Clymenella torquata.

Local distribution of the polychaetous worm Clymenella torquata. This is likewise determined by the character of the bottom, but is almost the converse of that of Nereis pelagica, the present species being in a large degree restricted to a muddy habitat.

The prostomium has a cephalic plate with a leathery rim, as seen here. Dorsal is to the right and ventral is left in this photo.

This closeup of the prostomium (bottom) and pygidium (center) of a coiled individual shows the partly-extended anal funnel on the pygidium, plus the setae on setigers 1 and 2 are partly visible. The notopodia are long capillary setae and the neuropodia are uncini.

This closeup of the setae on one of the segments shows the typical arrangement--long capillary notosetae (right) and a row of short uncini for neurosetae (left). Anterior is down in this photo.

This closeup of setiger 4 shows the notosetae and neurosetae, plus the then menbranous sheath that extends anteriorly around the posterior end of setiger 3 (bottom of photo).

Several of the longest segments appeared to have many eggs in the coelomic space.

Clymenella torquata (tentative), about 9 cm long, from 107 m depth in the San Juan Channel. The slanted head is at top right, and the orange funnel on the pygidium is partly extended. (Photo by: Dave Cowles, July 2014)
