Molgulidae Molgula euplicata Herdman, 1923 (Figures 31, 32) Herdman, 1923: 15. Monniot & Monniot 1983: 102 and synonymy; 1994: 34. Stations (events when several trawling operations per station): 27(33)-49A-57-59. Numerous specimens were collected between 450 and 1250 m depth. They seem to be free living on the sediment. They are globular, covered with sand and hair-like processes. The sessile siphons, difficult to detect, are distant of half the body length. The soft tunic is easily removed from the body wall. The edge of the oral siphon has 6 pointed lobes. In addition to the sphincters, strong muscular ribbons start from the siphons but do not reach the ventral body side (Figs 31 B, 32A), and a felting of criss-crossed thin fibres are distributed on the whole body wall. Twelve to 14 flat and short oral tentacles, with only primary branches alternate with 2 orders of smaller ones, the smallest being button-like. The dorsal tubercle is clearly protruding, opening in a C and located into a wide curve of ... : Published as part of Monniot, Françoise, Dettai, Agnès, Eleaume, Marc, Cruaud, Corinne & Ameziane, Nadia, 2011, Antarctic Ascidians (Tunicata) of the French-Australian survey CEAMARC in Terre Adélie, pp. 1-54 in Zootaxa 2817 on pages 44-52, DOI: 10.5281/zenodo.277174 ...
