Length at first maturity / Size / Weight / Age
Könsmognad: Lm ?  range ? - ? cm
Massive. Lobate to repent branches with fistules that break off easily. Black externally and internally. Smooth surface with scattered membrane bearing oscules; 0.3 - 0.5 cm in diameter, located on top of volcano-shaped elevations. Brittle to pulpy in consistency (Ref. 415). May appear as thick encrustation, usually partly buried or heavily covered with sediment. Releases black exudate when damaged. Oscules round and irregularly distributed; with thin walls (Ref. 85482).
Very common between coral rubble, in shallow reefs, seagrass beds, and mangroves (Ref. 415). Common on shallow lagoon bottoms; encrusting dead corals or rocks (Ref. 85482).
Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | 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.
