Platynereis dumerilii ?

[Franz Neidl]

I would be very happy to know if this is really the famous worm Platynereis dumerilii.
I found this fast swimming animal yesterday in the nocturnal plankton and it was about 5mm long.
It is famous because it can be bred in the laboratory and there are many studies about its eyes, the lunar rhythmus, the evolution ecc.,
cfr. the Platynereis homepage: http://www.uni-giessen.de/~gf1019/home/

Sorry but not Platynereis but another family called Syllidae, this is actually a reproductive stolon that has been released from the "mother" or "father" animal.
