here is one more Chromodoris tritos from the Maldives, Ellaidhoo Is., divesite "Orimas Faru", size 2 cm, depth 14, date Nov. 1996.

I saw about 10 specimens at Ellaidhoo. Two of them had black spots and smaller red ones. I don't know if Chr. geminus is reported with red spots.

Thanks Erwin,
I have arrowed the two red spots in your photo. Because of the nature of the pigment involved in the dark brown/purple spots of these animals, when pigment density is low the spots appear red or reddish brown. This can often be seen in juveniles, but also in adults. I have seen this in Chromodoris kuniei, and you can see it in photos of juveniles on the Chromodoris geminus, and Risbecia tryoni pages.
