Concerning message #19854:
Here is a shot of a Ceratosoma sinuata / C. flavicostata ...
it fits somehow both descriptions: the long central lobe at the head makes it C. sinuata, the whitish mantle margin and red colour makes it C. flavicostata.
Locality: Gato Nudibranch City, Malapascua Is., 12 m, Philippines, Pacific Ocean, 11 Oct. 2003. Length: 31 mm. Photographer: Erwin Koehler.
So, what is it?
Erwin@Philippine-Sea-Slugs.comKoehler, E., 2007 (Jun 19) Ceratosoma sinuata or what?. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/19998
This is precisely the reason I left them all as 'one species' for 10 years [message #19853]. While there are extremes which fit the various names very well, there seem to be a lot of intermediates.
If there is more than one species I suspect this is C. magnifica. If this is the case, then this species is not restricted to the western Indian Ocean.
