Rostanga pulchra from San Juan Islands

September 19, 2005
From: Paul Sim

Hello Bill.
This photo comes from a divesite in the San Juan Islands where I counted 20 species of nudibranchs on a single dive. Is this some kind of record? On a nearby islet I counted 22. If you are intersted I could list them out for you. Anyway, I have named this Rostanga pulchra because I could not find anything else that seemed to match although I have never seen one as red as the images on your website. I have several photo's from around British Columbia and the San Juans and they are all orange. Do I have the species wrong?

Locality: Bell Island, San Juan Islands, Washington, USA. NE Pacific. Depth: 50 feet. Length: 7 mm.1 July 2005. Wall and Rocks. Photographer:

Dear Paul,
It ceratainly looks very pale but the rhinophores and the caryophyllidia on the mantle suggest Rostanga, and as R. pulchra is the only species known from there I assume your is a juvenile. Hopefully someone will confirm that for us.
Best wishes,
Bill Rudman
