Material. Nha Trang Bay: Mot Island, coral rubble, 7 m, May 2008, 12 specimens; Tre Island, coral rubble, 6 m, Jun 2008, 18 specimens; Tre Island, biofouling, intertidal, Nov 2009, 6 specimens; Mung Island, coral rubble, 12 m, May 2008, 15 specimens; Nok Island, coral rubble, 5 m, 8 specimens; Diamond Bay: coral rubble, intertidal, Jun 2008, 25 specimens; Nov 2009, 16 specimens; Mar 2010, 8 specimens.
Description. Trunk up to 70 mm long, 4–5 mm wide, light brown or grey, with minute brown papillae, semitransparent; introvert shorter than trunk. Anal shield consists of white rhomboid or polygonal mosaicly arranged, calcareous units, with a dark central pore; caudal shield absent. Introvert protruded through the center of the anal shield; bidentate hooks arranged in rings distally. Longitudinal musculature continuous; retractor muscles originate in the middle of the trunk. Gut with 10 loops. Nephridia are about 70–90% of trunk length, completely attached to the body wall.
Discussion. This is the only species of the genus Cloeosiphon , and because of its unique configuration between the anal shield and the introvert by far the most distinctive species of sipunculans.
This tropical species is widely distributed in the Indo-West Pacific. In the West Pacific it has been reported from Australia to Hainan Island, inhabiting coral rocks in shallow water.
