Dear Bill,

Finally I have realised that I had a slight confusion of identity Re: Dendrodoris fumata. I previously thought that the species was Dendrodoris nigra, but your recent post of Erik Schloegl's photo prompted me to look at the page and...BINGO there was my suspect. Thanks for the great information source you have provided to us enthusiastic divers and other kinds of marine life enthusiasts.

Dear Akos,
Glad to be of help. These two species of Dendrodoris with their similar range of colour variations, are not easy to separate. I think the shape, number and position of the gills are the simplest chracter to use but this can sometimes be a trap for the unwary as well. A number of specimens of Dendrodoris nigra have been illustrated in the past with very large gills, extending out far beyond the width of the animal. This species characteristically has small gills. I suspect they have been accurately drawn/ painted/ photographed with large gills because the specimen has been kept for a long period of time in a small quantity of sea water. As the water becomes warm and oxygen levels drop, the gills often expand and become quite flaccid.
Best wishes,
Bill Rudman
