December 5, 2006
From: Mike Krampf


Note added 4 March 2008: Following Pola et al (2008) the name N. rutilans has been replaced by Nembrotha purpureolineata [see message #21419].

Concerning message #18378:

Here is a picture of Nembrotha rutilans mating that was taken in Lembeh Strait. The second picture of the solo Nembrotha rutilans was just a few feet away....maybe waiting his/her turn?

Locality: Lembeh Strait, 30 ft, Indonesia, Celebes Sea, 28 October 2006, Fringing reef. Length: 4 cm. Photographer: Mike Krampf.

Dear Mike,

Thanks for these photos, which remind me of Roberto Sozzani's photos [#13711]. As I said then, it will be interesting to see if penial shape can be used to distinguish different species. We often used the penis shape of the preserved animal in descriptive work, but its always a bit risky to compare shapes between species because the penis is usually contracted and 'inside out' and often distorted by the preservation process. It's obviously not  going to be an easy character to use as it is not often we find mating pairs which are able to be well photographed.

Best wishes,
Bill Rudman
