Goniodoris felis from Kerama Is.
September 12, 1999
From: Atsushi Ono
Dear Bill,
Thank you for helping with my unidentified aeolid.
Now, I found Goniodorid species at Kerama Is. [near Okinawa] in Japan.
It has white patches and lines on its translucent body. I found this at 15m depth, 10mm long, in May, 1999.
Could you help me to identify this one?
Sincerely,
Atsushi Ono

Ono, A., 1999 (Sep 12) Goniodoris felis from Kerama Is.. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/1328Dear Atsushi,
This is Goniodoris felis which was described by Baba from Sagami Bay. The one specimen and coloured illustration he had available were of quite a pale specimen. Your animal and the ones I have seen from Hong Kong (Rudman & Darvell, 1990: Pl 1B) have more dark brown on the dorsum.
Have you found this species often? If so is it associated with any food item. Species of Goniodoris are often found on the colonial ascidian colonies they eat. Because their bodies are partly transucent and partly pigmented with shades of brown and white they are usually very well camouflaged. As I have shown with Goniodoris meracula they also often live in cavities they eat out of the ascidian colonies, which only makes them even more difficult to find. As with many cryptic species, the egg masses are the best clues to their presence.
best wishes,
Bill Rudman.
