Re: Glossodoris atromarginata from Malaysia

Dearest Bill,
Recently I came back from a fantastic dive at Jarak Island, West Coast of West Malaysia.

Was diving at Whip Garden, at a depth of near 18m while conducting a diving course with a student. The bottom contour were of dead corals, sponges and algae. Found a pair of nudies which I believe should be of Glossodoris atromarginata. (Refer pics I've taken of each). Both were of about 3cm in length only. And each was about 1 meter apart from each other. One was pretty stationery while the other was crawling actively

Strange thing is, just a few centimeter away was another white nudie of about 1.5cm length. Could this be a juvenile? Or of same family? (Lower right photo).

Would appreciate if you can help identify the little white one.
Thank you,
Asther M. Lau

Dear Asther,
The two with black edges to the mantle are Glossodoris atromarginata but the white one is something else. It is almost certainly a species of Glossodoris but jst which one I am not sure. Juveniles sometimes lack colour characters found in adults, which makes identifying juveniles difficult at times. For example it seems to have traces of an opaque white pattern doen the dorsal midline which could indicate it is Glossodoris pallida and it could possibly be Glossodoris misakinosibogae without the black. Basically I am not sure
Best wishes
