Dear Bill,

Here are some photos of Dendrodoris nigra from Edithburgh Jetty, Yorke Peninsula, South Australia in Jan 1999.

Dear Stuart,
This is Dendrodoris fumata not Dendrodoris nigra. Have a look at my comments on each page to see the differences. These two species have been confusing us for over a century as both have the same range of colour forms. One good difference seems to be the shape and number of gills. In D. fumata there are a few (usually 5) large gills, which are usually extended out to the mantle edge. In D. nigra there are many small gills arranged in a cup-shaped circle.

In both your photos I think I can see parts of the bright yellow egg ribbon. It also appears that the sponge they are on is a food source.

Best wishes,
Bill Rudman.
