Hi Bill,
I think this is Glossodoris cincta again.
These were taken at Similan Islands, Thailand
Dive site: Snapper Alley - Koh Bangu
Depth: 7m
Date: January 2002
Cheers,

Van Belle, D., 2003 (Jan 11) Glossodoris cincta with defensive mucus. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/8859Dear Danny,
It is indeed G. cincta. What is very interesting is your photo showing the milky defensive secretions from what I call the 'mantle glands'. European workers usually call them 'mantle dermal formations' or MDFs for short, because they have found no secretory pores in histological studies. I haven't found any pores either, but I have certainly seen streaming secretions such as this. See the Defensive Secretions page and an earlier message where I discuss this more fully.
Best wishes,
Bill Rudman
