Rostanga sp. (undescribed)

We will designate this new species as Rostanga sp. 8 in the new Indo-Pacific Nudibranch book due out next month.

The rhinophores give the identification of this species away as they are characteristically "Rostanga" shaped and white in color. The gill is also typical, with the branches curved inward. It is grey in color. This species is pinkish grey with a complex network of light colored lines. It is found on sponges of a similar color pattern in which the nudibranch is well camouflaged, eluding divers for many years.

Although previously known only from Papua New Guinea, this occurrence adds Indonesia, and we'll be looking for it during our Nudibranch Workshop next March in Anilao, for sure.

Jim has been a solid supporter of the Slug Site since day one. His countless contributions put him near the top of the list of photographers who have greatly expanded our knowledge of sea slugs. There are a lot of kids in the formative stage of their education who are getting their first introduction to our sea slug friends via the great photographs Jim and other contributors have made to the site. My hat is off to Jim for making this presentation possible!
