Description
Summary:Stelodoryx oxeata sp. nov. (Fig. 8 a–f, Fig. 9 a–b) Material Holotype: USNM 1084236 (51° 19.969' N, 179° 30.194' W, Amchitka Pass, 176 m depth, 0 3. 0 8. 2004); Paratypes: USNM 1084237 (51° 38.292' N, 179° 34.651' W, Amchitka Pass, 395 m depth, 0 5. 0 8. 2004). AB J 2104­11­1 a (51° 39.397' N, 179° 35.028' W, Amchitka Pass, 712 m depth); AB J 2103­16­1 (51° 50.946' N, 179° 50.855' E, Amchitka Pass, 586 m depth); AB J 2104­13­1 (51° 38.292' N, 179° 34.651' W, Amchitka Pass, 395 m depth). Description This species was observed to occur in two growth forms. One is a stalked conical with a ridged surface (Fig. 8 a), the other is a massively encrusting, lobate sponge with a smooth surface (Fig. 8 b). Generally the smaller specimens have the conical growth form while the larger specimens are more lobate. Both growth forms are greenish and of rather hard consistency and only slightly elastic due to the densely packed spicules in the ectosome. Skeleton: Ectosomal very dense, tangential arrangement of tornotes, ... : Published as part of Lehnert, Helmut, Stone, Robert & Heimler, Wolfgang, 2006, New species of deep­sea demosponges (Porifera) from the Aleutian Islands (Alaska, USA), pp. 1-35 in Zootaxa 1250 on pages 13-17, DOI: 10.5281/zenodo.173010 ...
