Description Aeolidia papillosa is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusk in the family Aeolidiidae. A. papillosa has many common names including the shaggy mouse nudibranch or the shag rug nudibranch, in part due to its shape and its numerous flattened cerata that make it look rather like a bedraggled mouse or like a shag rug.

It can be easily identified by its large number of flattened cerata on its body except for a triangular area that extends from the rhinophores to the mid dorsum. The cerata vary in color from grey to white and sometimes pink, orange, or green hues, depending on the species of anemone it has been feeding on. Though sometimes smaller, this species can grow to a length of 10 cm(4 in) in the Pacific Ocean and up to 12 cm(5 in) in the Atlantic Ocean. The maximum recorded length is 100 mm.


Habitat Rocks, Piers, driftwood & pilings, Mud flats.


Range Western Canada, Mid-Atlantic, California, New England, Northwest, Eastern Canada, Alaska.
