					Expose portion appears as yellow papillae; the rest of the body buried in substrate, i.e., individual cells secret material that fragments small pieces of the sponges into the substrate (Ref. 865). Bores into abalone, oyster and barnacle shells (Ref. 865).

					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.
