Feeding of Dirona albolineata

March 17, 2008
From: Jackie Hildering & Glen Miller

Enjoyed finding this specimen feeding on hydroids on the outside of what I think is Spiochaetopterus costarum. We've previously submitted photos (message 12533) of Flabellina triophina feeding on the same prey but misidentified the worm species and initially thought the nudibranch was feeding on the worm!

Locality: Bear Cove, 40 feet, British Columbia, Canada, Pacific Ocean, 27 October 2007, Sandy bottom. Length: 13 cm. Photographer: Jackie Hildering.

Hi Jackie and Glen,

What a fantastic photo. Beautiful. You can really see the smooth lines of the frontal veil and the angular shape of the cerata.

I am not sure I can conclude that this specimen is actively feeding or just out for a cruise. Without a shot of an open mouth, or some gut analysis, this will have to remain a mystery.

Thanks for sharing,
Dave Behrens
