About Dysidea arenaria
Dysidea arenaria is a marine sponge in the family Dysideidae, a group with an organic-fibre framework that can incorporate sediment particles. A species-labelled field reference is available from the Institut de recherche pour le développement's Polynesian sponge collection. Hawaiian material published as Dysidea cf. arenaria is explicitly qualified and must not be substituted as an exact identification of this species. The Atlas keeps that distinction visible: a similar-looking photographed sponge is comparative evidence, not proof of the identity of the Kauaʻi source record.
The Kauaʻi evidence comes from a historical source record dated 1996, retained as “Dysidea arenaria” in Appendix A printed p. 72 of the cited survey. This preserves evidence of the reported occurrence; it does not establish present-day distribution or abundance.
