About Halichondria (Halichondria) melanadocia
Hawaiian material identified as Halichondria melanadocia has a dark gray to black outer surface and a dull-yellow interior. The 1967 account described a very soft, easily torn sponge with small surface projections and water outlets raised on low cones. It was found in a fouling community on the Coconut Island floating pier. Its color contrast is helpful descriptive context, but the species determination also rests on microscopic skeletal characters and comparison with previously examined material.
The Kauaʻi evidence comes from a historical source record dated 1996, retained as “Halichondria melanadocia” in Appendix A printed p. 70 of the cited survey. This preserves evidence of the reported occurrence; it does not establish present-day distribution or abundance. The historical source name and the current name are retained together so the record can be traced through taxonomic changes.
