Neptune's Cup Sponge Surveys

Once thought extinct, Neptune’s Cup Sponge (Cliona patera) was rediscovered in Cambodia. Aptly named, the sponge grows in the shape of a giant wine chalice and was previously overharvested as a novelty item for collectors and museums with one huge specimen even used as a child’s bathtub. With many located in the Koh Sdach Archipelago we undertake regular monitoring to assess growth rates and distribution of this species.
