From: Marli Wakeling
Hi Bill,
Here's the "largest" Doto amyra I have ever encountered. I found it this past summer in a remote area of British Columbia called Seymour Inlet.
Locality: Cotton Channel, Seymour Inlet, 30 feet, British Columbia, Canada, Pacific, 1 September 2006, Boulder covered channel. Length: 15 mm. Photographer: Marli Wakeling.
Cheers,
Marli Wakeling

Hi Marli,
Thank you for sharing these great close-ups of Doto amyra. As I am sure you are aware, Jeff Goddard has demonstrated 3 or 4 variants of this little critter. I am not sure I can drop your pure cream colored critter into one of those, but it is definitely D. amyra.
Goddard has shown that the different variants not only occur at different locations along the nominal species geographic range, but feed on different cnidarian prey. I cannot be certain, but the prey your specimen is on looks to me like the hydroid, Grammaria, which occurs in the area you took these photos. Maybe Jeff will reply on his thoughts about this color, and a food prey of Grammaria.
In any event your photos do show some interesting details about the morphology of this genus. With Bill's help cropping tight close-ups you can see the characteristic fluted rhinophores found in the genus. Also noted in the lower right close-up are the knobby, low tubercule covered cerata.
Great stuff. Thanks,
Dave Behrens
