Polyclinidae Aplidium balleniae Monniot & Monniot, 1983 (Figure 4) Monniot & Monniot, 1983: 13 fig. 2B, C, D. Primo & Vazquez 2007: 1777 fig. 2. Stations: 5-12-14-22 -61. One or several elongated lobes are united at their base. Each lobe is composed of a thick short peduncle and a softer head (Fig. 4). The tunic is encrusted with fine sand, but allows seeing long double rows of zooids. The common cloacal openings are apical but some can also be found on the lateral sides of the lobes. It is difficult to extract the zooids from the resistant vitreous tunic containing thin mineral particles. The oral siphon has 6 lobes. The atrial opening is wide; it begins at the level of the 3th or 4th stigmata row to end at half-length of the thorax. The languet with 3 teeth is longer near the common cloacal aperture. The branchial sac has 18 to 22 rows of 10 stigmata on each side. The 5 stomach folds are not well marked; an annular post-stomach is followed by a short segment of intestine which forms the bottom ... : 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 10-17, DOI: 10.5281/zenodo.277174 ...
