Eubranchus sanjuanensis from British Columbia

From: Clinton Bauder

Hi Bill,

Just got home from a week of diving in the Port Hardy area of British Columbia near the north end of Vancouver Island. Visibility was pretty awful for the first two days of the trip which was too bad for me as I was hoping to make use of my new wide angle lens. On the other hand it was probably a good thing for the forum as I switched to the 105 mm macro and went looking for nudibranchs.

This is Eubranchus sanjuanensis in both the pale orange form seen in earlier posts and the bright red version seen in the Behrens and Hermosillo book.

Locality: Hussar Point, 20 meters, British Columbia, Canada, Pacific, 26 August 2007, Rock Wall. Length: 6-8 mm. Photographer: Clinton Bauder.

Thanks Clinton,

Wow - another sighting of a species that has not been since since it was described. This is definitely Eubranchus sanjuanensis. Your specimens match Rick Zades from Port Townsend, Washington perfectly. Yours also show the variation between specimens.

Thanks for sharing,
Dave Behrens
