Concerning message #23342:
Thanks for the ID correction, Doc.
Responsive to your query, here are a few images of the C. granulosa crawling on the orange-red colored "whatever-it-is", perhaps algae, on which I found the slug. In the frigid water, I didn't linger long enough to find out if the slug was actually feeding on it.
Locality: Verdansky, 30 feet, Antarctic Peninsula, Southern Ocean, 14 March 2009, Rocky sloping reef. Length: 3/4 inch. Photographer: Kevin Lee.

Thanks for your quick response. I am definitely more comfortable lingering over your photos on a sunny Sydney day than you were taking them in Antarctic waters!
I agree the red-orange object is algal, which means there is something animal and orange, and probably cnidarian, nearby.
