Body translucent orange to orange yellow, and sometimes almost white with little sign of orange. The rhinophores and oral tentacles are also orange and when not damaged have a white tip. A variable number of white specks are scattered over the dorsum. The cerata are translucent clear with the dark brown digestive gland showing through the ceratal wall. There can be a white band about two-thirds of the way up each ceras and a white tip. The rhinophores are slightly shorter than the longest cerata and have about 15 distinct annulations in larger specimens. The cerata are arranged in rows as can be seen in accompanying photo. Found from the intertidal to about 20m, and grows to about 25mm long.
