Dendrodoris nigra colour variation from Reunion Island ?
May 15, 2007
From: Philibert Bidgrain
Dear Bill,
Reunion Island seaslugs
This species is relatively frequent in our island and isvery variable in colour. Reunion Island, Indian Ocean, Intertidal rocky coast
I send you different specimens. I think they are all Dendrodoris nigra....
In specimen 2 do you think that the more important white tips corresponded to milky acidic secretion?
What's your opinion about this identification?

Bidgrain, P., 2007 (May 15) Dendrodoris nigra colour variation from Reunion Island ?. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/19586Dear Philibert,
The upper two animals are D. nigra and the white spots represent regions where there are small single-celled glands which exude a white secretion.
The lower animal has a cup-shaped gill circle somewhat reminiscent of D. nigra, but in this animal the gills are proportionally much smaller. This is a quiet unrelated animal, Actinocyclus verrucosus. It has a much tougher, almost leathery mantle, and scattered patched of small raised black spots.
Best wishes,
Bill Rudman
