Glossodoris hikuerensis with egg ribbon

June 30, 2008
From: Lawrence Neal

Dear Bill,

Please find a couple of pictures of a pair of Glossodoris hikuerensis in the process of laying eggs during a night dive (I'm not sure if both slugs or only one was laying eggs). Both the Nudibranchs and the egg ribbon were very large and impressive.

Locality: Lembeh Island, 20 metres, North Sulawesi, Indonesia, Lembeh Strait, Celebes Sea, 20 February 2008, White sand, mixed coral. Length: Approx. 100 mm. Photographer: Lawrence Neal.

Thanks and all the best,

Lawrence

Dear Lawrence,

I haven't seen the egg ribbon of G. hikuerensis so this is an interesting find. At the risk of sounding a tad ungrateful, did you actually see one of them actually laying the egg ribbon? I have looked very carefully at your high resolution photos and as I can't actually see the female opening I can't be 100% sure that egg laying is taking place, There is always a possibility that these two animals were attracted to a food sponge that the eggs were already attached to. Certainly if someone else has photos of G. hikuerensis in close association to similar egg ribbon it would make me a little more confident of its identity.

I must say the photo of the gills is very spectacular. Many of the larger species of Glossodoris have the gills arranged not in a complete circle but in an arc around the anus, and at the ends of the arc smaller gills form a vertical spiral, greatly increasing the number of gills. I have not seen one quite as elaborate as yours.

Best wishes,
Bill Rudman
