Diversidoris crocea is a species of colourful sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae. Distribution This species is found in the tropical western Pacific, including: Indonesia, Philippines, Solomon Islands, Guam, and south to Queensland, Australia. Description This nudibranch is usually less than in length. It has a yellow body with a pale mantle margin that has two semi-permanent mantle folds about mid-body. The rhinophores and branchia (gills) are also yellow. However, identifying individual yellow sea slugs within the genus Diversidoris can be challenging because yellow forms which mimic their food, yellow sponges, exist in many related species. Ecology This species is often found on the yellow sponge Darwinella, which appears to be its preferred food source. References External links Chromodorididae Gastropods described in 1986
