This nudibranch reaches a maximum size of 14 mm, but commonly it is under 10 mm in adult size.
The body is colorless, but the cerata are colored due to the digestive glands inside them. The color of the digestive gland can be creamy yellow to orange-red to brown, depending on the color of the hydroids that an individual specimen has been eating.
This nudibranch feeds on hydroids.
