Ecology
Sessile; depth range 5 - 80 m (Ref. 363). Subtropical; 46°N - 25°N, 19°W - 36°E
Eastern Central Atlantic and the Mediterranean.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 30.0 cm WD male/unsexed; (Ref. 363)
Massive sponge; on surface equipped with conules very irregularly dispersed. A thin and generally smooth ectosome covers the surface gaps. Sponge: traversed great gaps méandriformes. Rare primary fibers: 0.0060 to 0.01 cm diameter; formed by the anastomoses of several fibers at their end in the conules; and containing foreign bodies. Secondary fibers: 0.0025 to 0.003 cm diameter. Coloring: darkish gray with yellowish on the surface, often brown white orange inside (Ref. 363).
Importance: It is the principal species currently exploited. The essence of the production comes from Tunisia. It is used for the domestic uses, the toilet and certain industries (Ref. 363).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the class Demospongiae are hermaphroditic. Life cycle: The zygote develops into parenchymella larva (free-swimming) before settling down on a substrate where it grows into a young sponge.
