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.
