Diversidoris flava is a yellow species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae. Distribution This nudibranch was originally described from East Africa, but it has an Indo-West Pacific distribution including Australia (Queensland) and Hawaii. Description This species is usually less than in length. It has a yellow body with an identifying red mantle margin which has two semi-permanent mantle folds about mid-body. The rhinophores and branchia (gills) are yellow. Identifying individual yellow sea slugs within the genus Diversidoris can be challenging because yellow forms exist in several related species. Ecology This species is often found on the yellow sponge Hyrtios, which appears to be its preferred food source. References External links Chromodorididae Gastropods described in 1986
