Opisthobranch of the Week Data
Dermatobranchus ornatus is considered to be very rare on Okinawa as I have seen and collected a total of only three individuals; all three animals were simultaneously collected, as they were found, in a fairly tight ball wound about each other. They were found in an area of mixed sand, coral ruble and a large patch of Caulerpa sp. algae. I've added an additional page showing the other two collected individuals as well as a group photo of all three variably pigmented animals together. Some members of the species possess large tubercles having elevated orange rings; Wolfgang Seifarth has a terrific photograph from the Red Sea of one of the orange-ringed animals on his German Slug Site.
As of the current date (Early-April, 2014) thirteen described species of Dermatobranchus from Okinawa's main island and the Keramas are featured on these pages. These thirteen species are:
I do have, however, a series of considerably smaller unidentified members of the family which seem to be quite dissimilar and are perhaps undescribed species.
