Notodoris serenae from Tufi, Papua New Guinea

October 2, 2001
From: Des Paroz

Dear Bill
Attached are 2 photos of what I believe to be Notodoris serenae, taken at Stewarts Reef, offshore of Tufi in Oro Province, Papua New Guinea. Depth was about 24m, and the water temp was around 28C. The third photo shows an egg mass that was spotted first. The nudi was then found only a few centimetres from the mass.

Note that the nudi also seems to have an injury or deformity in the "tail section". I have to say that this is one of the most elegant looking slugs I've yet seen.

Best regards
Des

Thanks Des,
Your photos show very clearly how the three protective tubercles which protect the gills in the yellow species of Notodoris, such as N. minor, have become almost decorative in this species. Concerning the egg mass. As a general rule it pays to be suspicious about egg masses of unknown parentage. A nudibranch close by could mean that it has recently laid it, but it could also mean it was just crawling past. Certainly the colour and the shape are similar to the egg masses of other species of the genus.

And yes, the 'tail section' does seem to have suffered some recent damage.
best wishes,
Bill Rudman
