Glossodoris carlsoni

Rudman, 1986


Patrik Good 12/5/2012 Nightdive Southport Seaway, 3 metres, 23 degree, size about 10mm. Is this Noumea simplex? Am a bit confused with the yellow border. Found one similar on nudibranch.com.au but would appreciate a confirmation or the proper ID.

Deb Aston Looks like Noumea simplex to me.

Gary Cobb I would say this very well could be Glossodoris carlsoni Rudman, 1986

Patrik Good Thanks, Deb.

Patrik Good Hmm, need to investigate then as it might be No. 99 for the Seaway if I am not mistaken. Thanks, Gary.

Gary Cobb Nice work!

Patrik Good Due to the lack of regular white specks in the mantle (and of me collecting this critter) we have decided that the hunt for No. 99 is still open at the Seaway.

Patrik Good 6 Opisthobranchs found that dive: Chromodoris cf. reticulata (1), Hydatina physis (3), Glossodoris carlsoni without official status (1), Discodoris palma (2), Goniodoridella sp. 1 (1), Favorinus japonicus (1). The beautiful nudi spawn eating Favorinus japonicus looked very healthy, big and was crawling fast. Didn't find the usual abundancy of Goniodoridellas.
