The mantle is brown with blotches and spots of white and black. Much of the mantle is covered in high pointed translucent papilla which are greyish basally and whitish in the upper half. Dave Behrens in Pacific Coast Nudibranchs notes that one of its most distinctive characteristics is the pungent odour of cedar it gives off when handled. it feeds on bryozoans, and grows to approx 20mm long.

Another one for the forum. This is Acanthodoris brunnea. It was found in 10m of water on the sand near the Monterey Breakwater, California. It's about 20mm long.
The photo was taken by my dive buddy Sami Laine whose work can be be seen at http://www.kelpdiver.com.

Always nice to see a new animal. Species of Acanthodoris are not common in the Southern Hemisphere so its like finding something new for me.
