Concerning message #21369:

I believe this is a Hypselodoris whitei laying eggs. We found it in Milne Bay, Papua New Guinea.

Locality: Lawadi, Milne Bay, 12 feet, Papua New Guinea, Pacific, 10 November 2007, black sand. Length: 3.5 inches. Photographer: Douglas Hansen.

Thanks Doug,

Yes this is H. whitei. Although the white on the rhinophore tips and inside edge of the gills is not very obvious, it is clearly there. Concerning the egg ribbon - did you actually see it laying it? Why I ask is that since the egg-laying apparatus is on the right side of the body the photo doesn't actually show that the slug is laying the eggs. From your photos it is possible that the Hypselodoris  is crawling off after completing the egg ribbon, but it could also be that it is just crawling over someone else's egg ribbon. Sorry I am hard to please, but we don't have a photo of this species' egg ribbon so it would be nice to be sure.

Best wishes,
Bill Rudman
