Description: This Dorid nudibranch has the anus on the midline of the dorsum, surrounded by a single circle of gills which are enclosed by a common sheath but cannot be completely retracted into it. The dorsum has long, tapered papillae making it look spiky or fuzzy, but no conspicuous outgrowths such as cerata, and no yellow line around the margin. The rhinophores are long, slender, taper from the base to the tip, and are colored white or yellowish-white (photo). The pointed tail has a mid-dorsal ridge (photo). Color white or cream with small white flecks between the papillae. Length to 12 mm.
How to Distinguish from Similar Species: Several other small whitish dorids have gills which extend from separate pits, not surrounded by a common sheath. They also have no mid-dorsal ridge on their tail.
