Notodoris sp. 1.
Himmafushi Island, Maldives., depth: 13m, 15mm long, October 27, 1999. PHOTO: Erwin Koehler.
I am not sure if this is a juvenile of Notodoris gardineri as I have found it on the same sponge as large specimens of that species. It differs from other yellow species in having black rhinophores and round black spots. See Erwin Koehler's message below.Authorship details

Looking at your recent pictures of juvenile N. gardineri I think my Notodoris sp. 1 from the Maldives is this one too. I didn't know that juvenile Notodoris have black rhinopores...
I must admit I had forgotten about your Notodoris sp. 1. On reading my comments about your animal, I'm glad I haven't contradicted myself. I don't really know that juvenile Notodoris have black rhinophores, but it is certainly beginning to look like that. I did get the radula out of some juveniles some years ago, but their are no easily distinguishing differences I could find which would allow me to say they were juvenile N. minor or N gardineri. If juveniles do have black rhinophores than you are probably correct in suggesting these are juvenile N. gardineri, but I must say the regular black spots are rather unusual.

Here are some photos of Notodoris ? from the Maldives. Size: 15 mm, depth: 13m, October 27, 1999, Himmafushi Island, divesite:
Is this a juvenile Notodoris minor?

I'm sorry this message got lost at the end of last year but better late than never!
I used to think this was a juvenile of Notodoris gardineri but I am beginning to wonder of it is a distinct species. It certainly differs in having black rhinophores and small round black spots. I can't see much difference in the radular teeth between the yellow species but I should look (or someone should) to see if this small spotted animal is a juvenile or reproductively mature. Specimens I have seen in Australia are feeding on the same sponge as N. gardineri and N. minor so their food doesn't seem to be a very conclusive feature.
Basically I don't know so I have left it as Notodoris sp.
