Food of Tritonia festiva

July 31, 2006
From: Dong Bum Koh


Dear Bill,

Concerning the foods of Tritonia festiva, the soft coral Gersemia rubiformis is known to be one of its main foods, and the photo in my previous message [#17010] shows that another soft coral, Bellonella rigida, is also eaten.

Here are photos of two more food items. Could you let me know your comments?

Locality: Ul Reung Island, [N 37°35' E 131°00']-15 m, Korea, East Sea, 16 July 2006, -. Length: Approx. 40 mm. Photographer: Im Sung Hwang.

Best regards,
Dong Bum Koh

Dear Koh,
I am not an expert on cnidarians but the 'anemones' in the upper photo look as though they may be a jewel anemone [Order Corallimorpharia]. In Australia the common genus is Corynactis.

The red branching colony in your lower photo would appear to be a gorgonian soft coral. This nudibranch would appear to feed on a wide range of cnidarians including the octocorals (soft corals, gorgonians) and the pennatulacean sea pens.

Best wishes,
Bill Rudman
