| Summary: | Stelletta anthastra n. sp. (Fig. 3) Material examined. Holotype, USNM 1231429, in 70% ethanol, fragment of the holotype (ZSM 20140114), in 70% ethanol. Collected by Brian Knoth with a research survey bottom trawl from the FV Ocean Explorer; 17 June 2012, 225 m depth, 19.8 km WNW of Carlisle Island in the Islands of Four Mountains, eastern Aleutian Islands, Bering Sea (52°58.542” N, 170°23.322” W). Attached to a mass of sand and pebbles. Bottom water temperature = 3.9 °C. Description. Large, massive, whitish (in life), ovoid sponge, approximately 18.5 cm x 15 cm x 12 cm, hard, only slightly elastic consistency, no oscules visible. The surface is covered by many low elevations, similar to a cauliflower (Figs. 3A & B). Many small openings are visible under low magnification (16 X). We are not sure whether these openings are pores or oscules but they are ungrouped and scattered over the entire surface without any obvious pattern. In sections perpendicular to the surface the radial arrangement of polyspicular ... : Published as part of Lehnert, Helmut & Stone, Robert P., 2014, Aleutian Ancorinidae (Porifera, Astrophorida): Description of three new species from the genera Stelletta and Ancorina, pp. 341-355 in Zootaxa 3826 (2) on pages 350-352, DOI: 10.11646/zootaxa.3826.2.4, http://zenodo.org/record/230036 ... |
