That's an excellent shot - the depth of focus is very impressive. The gills come out especially well. You can see they are triangular in cross section distally and have white spots in a row up the inner face. Furthermore, I notice that the gills are all unipinnate. That is, all except one which has a tiny branch coming off it. This is a forerunner of the bipinnate condition which is normal for dorids other than chromodorids.
Rudman described it in 1995 (from New Caledonia) and Julie Marshall and I recorded it from Australia for the first time in 1999 (from Heron Island)
