Description The live sponge is massive, with rounded conules covering the surface (Fig. 22 A). The color is redorange. The fragments preserved in alcohol are beige in color; they have a digitate-conulose surface and a very firm consistence. SKELETON. The ectosome consists of a paratangential layer of thin styles (Fig. 22 B). The choanosome (Fig. 22 C) is made by a reticulation of multispicular primary fibers, 70 – 125 µm in section, and secondary fibers, 23 – 35 µm, forming irregularly rounded meshes around 150 µm wide. The fibers have a core of styles and are echinated by acanthostyles. SPICULES. Slightly curved and smooth styles (Fig. 22 D), sometimes straight, 145 – (176.5, 21.4) – 210 µm × 6 – (7, 1.1) – 9.5 µm; longer and straight subtylote styles (Fig. 22 E), microspined or smooth on the head, 198.5 – (230, 15.5) – 250 µm × 4.5 – (6.5, 0.8) – 7.5 µm; subtylote acanthostyles (Fig. 22 F), with smooth neck, 47.5 – (51, 4.9) – 72.5 µm; very thin toxas (Fig. 22 G), bent in the middle, 143 – 181 µm; palmate isochelae (Fig. 22 H) 11.3 – 14.6 µm.
