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). Common between 5 and 30 m of depth, would go down up to 80 m to Libya (Ref. 363).
Life cycle and mating behavior
половая зрелость | размножение | нерест | 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.
