Glossodoris from Mooloolaba

From: Wayne Ellis


Bill,
Here is another photo from Steve Grail, taken 10-20m, between 1996 -98 off Mooloolaba, Sunshine Coast. It has a brown margin. As far as I know G. atromarginata has a black margin, G. averni has red.
Regards,

I cannot be 100% sure without a specimen to dissect, but I am pretty sure it is a colour form of Glossodoris atromarginata. Although it is usually white with a black margin, some specimens are distinctly yellow with a white band inside the black margin, and some have a brown margin. In some the background colour is also quite brown. Another thing that varies is how "frilly" the edge of the mantle is. In some animals there are only a few folds while in others there are many. The three animals I have illustrated above cover the main variations. You should also be aware that in New South Wales there is another species, Glossodoris angasi which can be easily mistaken for Glossodoris atromarginata
