This tiny nudibranch is no bigger than 14 mm or 5/16″, but when examined closely it is a lovely aeolid with brightly coloured rings on its mantle and unusually sized and spaced papillae on its cerata.  These photos were taken in a protected rubbly, rocky area of North Kihei in less than one metre of water and in a shallow surge zone, Makena Landing. It is often confused, at first, for Limenandra rosanae, so take a look at both closely. For more information and photos please see Sea Slugs of Hawaii
