Discodoris concinna (Alder & Hancock, 1864)

Discodoris concinna is known from the Marshalls from about a dozen specimens found at Kwajalein and Enewetak Atolls, although their relative scarcity is due more to lack of search effort in their habitat rather than rarity. They have been found in the lagoon under dead coral or aluminum storm debris, and rarely on the leeward seaward reef in ledges and caves at night. At Kwajalein, four specimens, including both of those figured below, were found on one short search under concrete slabs dumped as shoreline reinforcement along central Kwajalein's lagoon shore at a depth of less than 1 meter at medium low tide. Many nudibranch workers consider D. concinna to be synonymous with D. lilacina. We do believe the species figured below is different from D. lilacina, although D. concinna might not be the right name for it. These animals differ from D. lilacina in typically being larger and having a more mottled pattern of gray and white rather than the distinctly spotted pattern seen on the specimens on the D. lilacina page. The photos below show an 80mm specimen.

The underside has large brown spots.
