Description

( Figure 8 View Figure 8 (c – d)). Sponge elongated, pear shaped or conical, sometimes laterally flattened, up to 5.5 cm in height and 4.5 cm in width. Body slightly narrows downwards forming a short peduncle, by which the sponge attaches on stones or on polychaetes tubes. The surface is rugose, sometimes nearly smooth (only juvenile forms). The consistency is soft and elastic. The single osculum of roundish or slit-like form (about 2 mm in diameter) is placed at the summit and surrounded by the short (about 0.8 mm in height) spicular collar (not always). Colour (in alcohol) ash grey or pale pink. Six specimens examined.

Skeleton

( Figure 8 View Figure 8 (a – b)). The main skeleton consists of a quite loose or diffuse network of spicule bundles and single spicules. Only near the surface, spicules (mostly small tylostyles) become more or less regularly arranged, and grouped in the radial bundles.

The cortex is composed of a thin layer of microscleres. In the underlying tissues (choanosome) microscleres are absent. Only in rare exceptions were they found in the walls of the aquiferous system.

Spicules

( Figure 8 View Figure 8 (e – h)). Styles (tylo- and subtylostyles) straight, rather short-pointed (spicules with blunt apical ends occasionally found), dimensions: 167.7 – 387.8 – 538.9 × 5.4 – 11 (n = 200) µm; microxea and microstrongyles centrotylote, spined, dimensions 16.7 – 38.29 – 62.9 (n = 60) µm and 8.2 – 19.57 – 36 (n = 60) µm, respectively.

Distribution

Bering Sea, West and East Greenland Shelf. Chukchi Sea, East Siberian Sea , Laptev Sea, Kara Sea, Barents Sea, White Sea, North Sea. Depth range: 5 – 113 m.

Remarks

Widespread circumpolar boreal-Arctic species. Quite polymorphic, and is represented by at least two morphologically close species. It is possible that some specimens of suberites montalbidus examined by Fristedt (1887), Lambe (1895) and Koltun (1959) are actually represented by a similar, newly allocated species, suberites cebriones sp. nov.
