Remark Shape and size.— Roundly lobate to thickly flabellate. Holotype consists of four separate pieces. The largest piece is 14 cm in width, 8 cm in height and 2.5 cm in diameter (diameter, height, width), but specimens can grow much larger. Colour.— Bright orange externally to cream-orange internally. Surface and consistency.— Texture: very soft, spongy; dermis is a bright easily dis- tinguishable membrane, with dense concentrations of conules. The conule height varies from 1 to 3 mm. Small apertures (< 2 mm) are scattered across the body, in between some lobes bigger pores (2-3 mm) may be observed connected to internal axial channels. Skeleton.— The interior is densely punctured by primary canals 200 µm-2 mm in diameter, from which secondary canals radiate, 100 µm-1.0 mm wide. The conules are reinforced internally by tracts of fibers. The skeleton is an irregular and dense reticulation of spongin fibres; primary fibres (35-80 µm in diameter), aggregated in packs, more or less undulated, heavily cored (1-7 spicules in cross section) and echinated; secondary interconnecting fibres (25-40 µm in diameter) are not cored and less echinated than the primaries; tertiary fibres (20-30 µm in diameter) present and echinated in a similar fashion as the secondaries, also uncored. Meshes irregular from 100-250 µm in diameter. Spicules.— Acanthostyles (N = 100) are straight, but a few are slightly curved; the whorls, measured in the middle third of the spicule, have 5-12 spines depending on the width, they are conspicuous in the spicule center but sometimes faint and irregular at the spicule tip and head; the average length of spicules is 187 µm (78.7-372.3 µm), the average width is 12.1 µm (5.2-24 µm) and the average number of whorls is 19.3 (11-33). Ecology.— Locally very abundant, overgrowing other reef invertebrates. Distribution.— Only observed at type locality, Peniki Island and the island Payang Kecil in the Thousands Islands Reef complex, off Jakarta, West-Java, Indonesia. Etymology.— The species is named to honour Carolus Linnaeus, or Carl von Linné, to celebrate 250 years of binomial nomenclature. [details] From editor or global species database
