Demospongiae | AgelasidaEnvironment: milieu / climate zone / depth range / distribution rangeSessile; depth range 10 - 35 m (Ref. 415). TropicalLength at first maturity / Size / Weight / AgeMaturity: Lm ?  range ? - ? cm Max length : 30.0 cm WD male/unsexed; (Ref. 415) Massive, roundish, occasionally lobate up to 30 cm wide. Two distinct color: bright orange, and reddish to walnut-brown externally, lighter orange or tan internally. The surface is smooth. There are 3 intergrading kinds of oscules: 1. meandering invaginations; 0.1 - 0.3 cm wide; up to 5 cm long; 2. circular oscule, 0.2 - 0.7 cm in diameter; 3. smaller, circular to elongate, 0.1 - 0.2 cm wide, flush (Ref. 415). Maximum depth from Ref. 108813. Coral reefs, usually below 10 m in depth (Ref. 415). It hosts alpheid shrimps in its canals (Ref. 86672). Commensal with amphipods (Ref. 82302). 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 (Ref. 833).
