Eubranchus rustyus from British Columbia

September 12, 2007
From: Clinton Bauder

Hi Bill,

Part one of three for various Eubranchus animals I found in British Columbia. I saw literally hundreds of similar looking animals but after spending some time looking at the images I'm having trouble sorting them into rustyus, olivaceus/rupium and misakiensis.

I think this animal might be E. rustyus. The coloration is more green than red and it doesn't have the white specs on it.

Locality: Hussar Point, 20 meters, British Columbia, Canada, Pacific, 26 August 2007, Rock Wall. Length: 4 mm. Photographer: Clinton Bauder.

Hi Clinton,

Eubranchus rustyus can be difficult to ID, but that is what you have here. Patches on the body and the shape and color of the cerata give it away. E. misakiensis is the closest to this species but it has large oval brown spots on the body.

Thanks,
