Stelodoryx mucosa n. sp. (Figs. 12 & 13, Table 5) Material examined. Holotype: ZSM 20150390, collected by Jim Stark with a research survey bottom trawl (haul #216) from the FV Ocean Explorer; 2 August 2012, 127 m depth, Stalemate Bank, western Aleutian Islands, North Pacific Ocean (52°59.0760' N, 170°55.5780' E). Water temperature = 3.7°C. Complete specimen in ethanol. Description. Habitus: Massively encrusting or possibly standing upright, golden brown colored sponge, approximately 19.5 x 23 x 3.5–4.3 cm (Fig. 12 A). The sponge was probably attached to pebbles and was noted as incredibly mucous laden. In ethanol it is still thickly covered with mucus which comes off in long sticky strands. The consistency is firm and only slightly elastic but the sponge breaks into pieces under its own weight when handled. The surface is rugose and uneven and there are different surface patterns in different areas (Figs. 12 A & B). Skeletal structure: The ectosome consists of a single row of tylote bundles, 300–550 ... : Published as part of Lehnert, Helmut & Stone, Robert P., 2015, New species of sponges (Porifera, Demospongiae) from the Aleutian Islands and Gulf of Alaska, pp. 451-483 in Zootaxa 4033 (4) on pages 470-474, DOI: 10.11646/zootaxa.4033.4.1, http://zenodo.org/record/253595 ...
