This is an exquisitely beautiful, very tiny aeolid that is pretty much impossible to see unless it is on a stark, contrasting background. The long fringe-like papillae on their rhinophores are stunning, but basically only visible with a macro lense. The animals photographed here were found in both North and South Kihei/Makena area in less than 6 ft (3 metres) of water. They were primarily white, but they can be mottled brown and most have brown markings on their rhinophores. To 11 mm (or less than 1/2″).
