Costaciella sp. 1 Undescribed
Well I think we have decided to call this cutie Costaciella sp. 1, in the new edition of NSSI. Thats about as close as we can come, if we can assumme that the marking behind the rhinophores varies between specimens.
The body is grey with green cerata. Each ceras has a subapical gold band. The rhinophores are white, tipped with gold. The black pigment behind the rhinophores appears to be variable from forming an oval to a series of randon blotches as seen in Gordon's photo here.
This species has a wide geographic distribution, occurring across the tropical Indo-Pacific and feeds on the algae, Avrainvillea sp.

This new 2nd Edition is updated and reorganized, including 185 new species. Among other features, the new edition includes additional photographs of species, an identification key, and an up-to-date classification reflecting the latest evolutionary relationships. The Indo-Pacific represents the largest expanse of tropical ocean in the world, stretching from the Indian Ocean coast of southern Africa and the Red Sea to the central Pacific of the Hawaiian Islands, Easter Island and the Marquesas.
This region supports the most diverse marine fauna of any place in the world for most groups of marine organisms. The nudibranchs and sea slugs are no exception to this rule; there are about 3,000 described species of these organisms in the world and at least 40% of these have been found exclusively in the Indo-Pacific tropics. This book illustrates 2,138 Indo-Pacific nudibranchs and sea slugs, including many undescribed species.
