Feeding in Chromodoris decora [1]
September 13, 2007
From: Scott Johnson
Hi Bill,
As a follow up to Denis Riek's message [#20634] regarding feeding in Chromodoris decora, here are a few more records from the Marshall Islands. The animals figured were certainly feeding on the yellow and gray sponges; I am not as certain that the third was actually feeding on the purple Chelonaplysilla violacea, although it looked pretty suspicious since the area just above the animal appears to have been grazed.
However, I am not convinced that these are Chromodoris decora, although I have to admit the situation to me is not clear. I will follow up on that comment in subsequent messages [#20696, #20697 ].
Locality: Enewetak Atoll, 4-5 m, Marshall Islands, Pacific, 1982 - 1883, Under rocks on lagoon reef. Length: 15-25 mm. Photographer: Scott Johnson.

Dear Scott,
This message, and your other two [#20700, #20701], give us a pretty comprehensive idea of the food choice of at least this 'colour form' of C. decora. As I also discuss in those messages, this species shows a remarkable similarity in diet to Chromodoris fidelis, eating all the sponges you recorded for that species, which were all species of Chelonaplysilla.
The upper photo shows the same unnamed yellow species as shown in messages #12232, #12231, #12221, the middle photo shows another unnamed species in message #12229, and the sponge in the bottom photo is Chelonaplysilla violacea, also eaten by C. fidelis [#12220].
Best wishes,
Bill Rudman
