Water temperature = 4.3°C. Complete specimen in ethanol. Description. Habitus: Large, light brown to gold colored, fan-shaped to flabellate sponge, starting from an almost circular base with a maximum diameter of 7 cm and a height of 26.5 cm, the upper rim approximates a quarter-circle, 25.8 cm in width (Fig. 8 A).
