| Summary: | Caulophacus (Caulodiscus) valdiviae Schulze, 1904 Material examined: SMF 10528/10607, 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. Description and remarks. Seven fragments, probably from a single sponge, were obtained at a far eastern station of the Weddell Sea along with a fragment of one other caulophacid. Included is part of the upper stalk with lower body attached, 68 mm long by 9.6 mm diameter at its mid-waist. The largest upper body part is a sheet, 63 by 64 mm in horizontal dimensions, with a maximum thickness of 6 mm. Spiculation of six of the fragments are identical, including typical dermal and atrial pinular pentactins and hexactins, hypodermal pentactins with coarse spination on the proximal areas of all rays, principal diactins, and smooth choanosomal hexactins. Microscleres consist mainly of discohexactins with very rough rays and onychohexasters with relatively long primary rays, ... : 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 page 16, DOI: 10.5281/zenodo.188483 ... |
