Petrosaspongia Bergquist 1995
No full textGenus Petrosaspongia Bergquist, 1995 Definition: Unarmoured Thorectinae with a dense secondary fibre reticulum rendering these sponges hard and incompressible. Very thin fibres, which seem to correspond to a tertiary network, are present in some places. Slightly modified from Cook and Bergquist (2002) Type species: Petrosaspongia nigra Bergquist, 1995 by monotypy.Published as part of Uriz, María - Jesús & Cebrian, Emma, 2006, Presence of the Indo – Pacific genus Petrosaspongia Bergquist, 1995 (Porifera: Demospongiae) in the Atlantic with description of a new species (P. pharmamari n. sp.), pp. 61-68 in Zootaxa 1209 on pages 62-63, DOI: 10.5281/zenodo.17242
Petrosaspongia nigra Bergquist 1995
No full textPetrosaspongia nigra Bergquist, 1995 pictures. Description External features Massive–lobulose with an unarmoured microconulose surface. Each conule ends in a thin projecting fibre (Fig. 1 A). Consistency stony, incompressible. Oscules spread on the surface, 1 –2.8 mm in diameter. Colour blackish outside, beige inside, in alcohol. Skeleton Reticulate with a dense network of secondary fibres forming meshes 80–225 m in diameter. They form fenestrate plates when they join the primary fibres. Primary fibres: 355–790 m in thickness, strongly cored by foreign debris (Fig. 1 B) Secondary fibres: 20–80 m (Fig. 3 A), laminated and completely free of foreign debris. (Fig. 1 B–C & Fig. 3 C). Through SEM, the surface of the secondary fibres appears rippled in a longitudinal direction (Fig. 1 C). Tertiary fibres: Very thin, rare. Choanosome containing abundant sand and other foreign materials (Fig. 1 D). Distribution: Southwest Pacific region, New Caledonia islands, from 10 to 38 m depth. Note. The re–examination of the holotype allowed us to measure the skeletal elements, and our results provide larger fibre diameters (particularly for the primary fibres) from those given by Bergquist (1995).Published as part of Uriz, María - Jesús & Cebrian, Emma, 2006, Presence of the Indo – Pacific genus Petrosaspongia Bergquist, 1995 (Porifera: Demospongiae) in the Atlantic with description of a new species (P. pharmamari n. sp.), pp. 61-68 in Zootaxa 1209 on pages 63-64, DOI: 10.5281/zenodo.17242
