Well here is another interesting nembrothid delema. When I first saw the photo I thought it was a faded aberrant variation of Nembrotha mullineri. With a few suggestions from webmaster Mike, I started to see the differences, the most important of which are the lack of large areas or brown and cream on the body, the series of white tubercles on the frontal veil, the deep blue color on the foot and mouth region and the coloration of the gill and rhinophores.

Similar to our discussion of Nembrotha cf milleri a few weeks back the mantle glands are easily seen as a red spot situated on the pores.

Apparently this fellow is not uncommon, having been documented from Rinca Island, Indonesia, Anilao, Philippines ( Jim Black , Michael Miller, Ali Hermosillo ) and Sabang Bay, Philippines( Martin Buschenreithner).

Back in December 2009 we were parked in Horseshoe Bay, Rinca, Indonesia, for virtually three weeks on the small boat MV Charlie for some great diving. We photographed over 130 species of nudibranchs, of which about a third we had not seen before, including this lovely undescribed Nembrotha. Shot in Torpedo Alley with my Nikon D200 and the old Nikon 105mm Micro lens in a Subal housing with an odd twin strobe setup of a Nikon SB105 and a Nikon SB25 land strobe in a 1994 vintage Subal housing (since replaced with a pair of Inon Z240s).
