Climate / Range
Thinly encrusting. Smooth surface. Black to gray in situ; greenish in alcohol. Skeleton: dendritic, in bundles of 10 to 20 megascleres rising individually from the substrate and dividing dichotomously. Spicule bundles, not forming a separate ectosomal skeleton, spread to carry the surface membrane which carries numerous scattered microscleres (Ref. 83467).
Encrusting undersides of coral rubble in shallow reef habitats. Also in lagoons and on mangrove roots (Ref. 83467). 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).
