Description
Size: Length 150-200 mm.

Color: Reddish brown in color, with a deeper tint towards the anterior end.

Elongated specimens with the anterior few segments circular and the remaining flat enclosed in leathery tubes. Tubes are straight with shell fragments. Sand particles and debris attached. Palps small and globular, two anterior tentacles shorter than the three posterior ones. Eyes absent. Gills appear on the fifth foot, with fairly long filaments covering the back, but decrease in size and disappear between 50th and 70th foot. Five long occipital tentacles arising from ringed ceratophores; a pair of small tentacular cirri. Branchia with spirally arranged filaments in the anterior 25-35 segments. Anterior 4-5 segments with winged capillaries and pseudo-compound hooks with hooded bidentate tips; remaining segment with winged capillaries, comb setae and acicular setae with bidentate tips. Two pairs of anal cirri. Some very small specimens measuring 1-2 cm are seen without the paired tentacular cirri with gills in anterior 10-15 segments.

This polychaete shows wide distribution due to its ability to tolerate changes in salinity.
