Chromodoris conchyliata laying eggs

May 8, 2007
From: Hugues Flodrops

Dear Bill,
In addition to my previous message about feeding observations [#19889], here is one picture of Chromodoris conchyliata laying eggs in the same pool, on another night. Twenty minutes before, there were no eggs so I'm sure that this specimen was laying eggs.

Locality: Etang Salé. Permanent pool, 1 metre, Reunion Island, Indian Ocean, 5 may 2007, Night since two hours. Length: 35 mm. Photographer: Hugues Flodrops.

Best wishes.

Dear Hugues,
Thanks again for a valuable observation. This is the first information we have on its egg ribbon. As we might expect, it looks quite similar to that of C. geometrica [see message #10872], a common species in the western Pacific, which is very similar in colour pattern and body shape. It also feeds on C. violacea and is probably closely related.

Best wishes,
Bill Rudman
