How to Distinguish from Similar Species: The cerata on Arminaceans such as this species often make them look a lot like Eolid nudibranchs, but they can be distinguished from Eolids because Arminaceans have the anus on a papilla on the rear third of the body (right side) while Eolids have it on the anterior third of the body (right side). Dirona albolineata has grayish white, salmon, or purple cerata with white lines and a white line around the foot and frontal veil and between the cerata but has no white splotches.
Geographical Range: King Island, Alaska to Puget Sound.
Depth Range: Shallow subtidal
