| Summary: | Stelletta makushina n. sp. (Fig. 2) Material examined. Holotype, ZSM 20140111, specimen in ethanol, collected by Robert Stone with a camera array towed from the FV Sea Storm; 8 August 2012, 177 m depth, 4 km NNE of Bishop Point, Unalaska Island, eastern Aleutian Islands, Bering Sea (54°00.499” N, 166°56.136” W). Attached to a large cobble. Bottom water temperature = 4.2 °C. Description. Irregularly ovoid sponge (45 mm x 38 mm x 32 mm) with a rough surface (Fig. 2A, left). Sponge is white in life but covered with a light brown spicule mat. No oscules visible, possibly due to dense layer of triaene cladomes above the surface. The consistency is hard, only slightly elastic. The megascleres protruding above the sponge surface pass through a pigmented, relatively thick, probably collagenous cortex, 500–700 µm in diameter (Fig. 2B). Long triaenes protrude through this cortex up to 2.5 mm above the surface (Figs. 2B & C). The cladomes of the outermost protruding triaenes (Fig. 2C) end approximately in the same ... : 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 343-349, DOI: 10.11646/zootaxa.3826.2.4, http://zenodo.org/record/230036 ... |
