White form of Eubranchus farrani from the Baltic Sea

January 13, 2010
From: Thorsten Walter


Dear Bill Rudman,
I am the owner of a small local aquarium/museum located at the Baltic Sea in Lübeck-Travemünde, northern Germany. During our field trips with school clases we sometimes found small nudibranchs, inside the harbour in front of our station. The salinity of the water is normally 1.0-1.5 psu.

Locality: Harbour, less than 1 metre, Germany, Schleswig-Holstein, Baltic Sea, 19 December 2009, On Laminaria covered mainly with Ciona intestinalis. Length: 6 mm. Photographer: T. Walter.

I think this is a species of Eubranchus.

It would be great if you or somebody else can help me with the species identification.

Best regards
Thorsten Walter

Dear Thorsten,

I am not a great expert on the North Atlantic fauna but I am pretty sure this is another colour form of Eubranchus farrani. It is not as colourful as your orange-spotted animal [message #23077] but IT could possibly develop some colour as it grows.

Best wishes,
Bill Rudman
