Roboastra gracilis from Indonesia
September 21, 2007

Bill and all --
Another from my Wakatobi trip. I believe, based on looking at a lot of pics, it's Roboastra gracilis ... but it's very slender compared to other pics, and the orange spots are barely visible on this specimen. Maybe a juvenile?
Locality: Wakatobi, 40 feet, Indonesia, Banda Sea, 31 October 2007, Sandy bottom. Length: > 2 inches. Photographer: E.F. Dixon.

Dixon, E.F., 2007 (Sep 21) Roboastra gracilis from Indonesia. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/20693Dear Ed,
This is a perfectly acceptable R. gracilis. They tend to 'fatten up' when they are sitting still, and because they are so slender we often unconsciously wait until they shorten a bit or turn a little so they fill the photo frame better. The brightness of the yellow spots is quite variable, as is the 'blueness' of the gills and rhinophores.
Best wishes,
Bill Rudman
