Eubranchus rupium? from British Columbia

September 12, 2007
From: Clinton Bauder

Hi Bill,

Part two of three in a series of Eubranchus. This one looks to me like Eubranchus rupium based on the white flecks on the rhinophores, more reddish markings and the transparent mantle. But, as I say in my previous message I'm having trouble distinguishing these guys.

Locality: Browning Pass, 15 meters, British Columbia, Canada, Pacific, 27 August 2007, Rock Wall. Length: 5 mm. Photographer: Clinton Bauder.

Hi Clinton,

Well the plot thickens. I agree with the ID, although not really typical. Again, you have documented the eggs, which are typical eubranchid. I think I'd like Sandra Millen and Jeff Goddard to chime in on this one

Thanks for sharing,
Dave Behrens
