Summary: | Caulophacus sp. Material examined: SMF 10608, ANDEEP III Exped., R.V. 'Polarstern', stn PS67/059-10, Weddell Sea, Antarctica, 15 Feb. 2005, 67°30.37'S, 0°03.74'E to 67°30.27'S, 0°04.34'E, 4648 m, ethanol; SMF 10609, ANDEEP III Exped., R.V. 'Polarstern', stn PS67/142-6, Weddell Sea, Antarctica, 18 Mar. 2005, 62°09.93'S, 49°30.47'W to 62°09.80'S, 49°30.59'W, 3403–3404 m, ethanol. Description and remarks: Two additional partial specimens, both stalks, attributable to Caulophacus, are inadequate to place more definitely. The first, from station PS67/059-10, collected along with C. (Oxydiscus) weddelli, is a small stalk, 91 mm long, 2.7 mm diameter at its narrowest point, and 7.2 mm at its slightly inflated upper end. It is a hollow tube composed of diactins thoroughly fused by synapticula, characteristic of Caulophacus stalks. Associated with it are a few slightly pinular spiny hexactins and pentactins as surface spicules, with ray lengths of 100–250 µm. The only microscleres present are oxyhexasters along with ... : Published as part of Janussen, Dorte & Reiswig, Henry M., 2009, Hexactinellida (Porifera) from the ANDEEP III Expedition to the Weddell Sea, Antarctica, pp. 1-20 in Zootaxa 2136 on pages 16-17, DOI: 10.5281/zenodo.188483 ... |
