Euchelipluma elongata sp. nov. (Fig. 10 a–b, Fig. 11 a–f) Description Yellowish colored whip­like sponge (Fig. 10 a–b), resembling species of Asbestopluma Topsent, 1901 and Esperiopsis flagrum sp. nov. (see below) Rigid long, thin stalk with thin, relatively short processes. The collected specimen is broken at the tip, but still 32 cm in length, attached to the substrate by a rigid root system. May attach to exposed bedrock, boulder, cobble, and pebbles partially buried in unconsolidated sediment. The axis is flattened, measuring 2 x 3.5 mm, with two rows of filament­like processes (0.1 x 7 mm) on the narrow sides of the axis. Skeleton: The ectosome consists of densely arranged isochelae, underlaid by paralleloriented fusiform styles with blunt ends and smaller tylostyles. Single tylostyles are placed perpendicular to the orientation of the styles and tylostyles.The choanosome is dominated by ascending polyspicular tracts of styles, tylostyles and isochelae. In the central axis of the stalk individual tracts ... : 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 17-20, DOI: 10.5281/zenodo.173010 ...
