Artemisina flabellata n. sp. (Figs. 8 & 9, Table 3) Material examined. Holotype: ZSM 20150387, collected by Jay Orr with a research survey bottom trawl (haul #135) from the FV Ocean Explorer; 11 July 2012, 99 m depth, Petrel Bank, central Aleutian Islands, Bering Sea (52°15.9960' N, 179°54.0060' E). Water temperature = 4.3°C. Complete specimen in ethanol. Description. Habitus: Large, light brown to gold colored, fan-shaped to flabellate sponge, starting from an almost circular base with a maximum diameter of 7 cm and a height of 26.5 cm, the upper rim approximates a quarter-circle, 25.8 cm in width (Fig. 8 A). The thickness of the blade is quite variable, the thickest part is 9 cm while other parts are less than 1 cm in thickness. There is a hole in the center of the blade, possibly from tissue necrosis (Fig. 8 B). No oscules are visible. The consistency of the base is hard and inelastic, softer and more elastic but, still resilient, towards the top. Skeletal structure: The ectosome is a relatively thick ... : 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 464-468, DOI: 10.11646/zootaxa.4033.4.1, http://zenodo.org/record/253595 ...
