Platydoris argo from Spain

From: Erwin Koehler


Bill,
Here are some photos of Platydoris argo from my recent trip to Spain, Cala Joncols near Roses (Costa Brava), July 2000. I met within a week 10 individuals, 4 pairs "trailing" like Risbecia. Schmekel and Portmann (Opisthobranchia des Mittelmeeres) write the maximum size is 55mm, Cattaneo-Vietti, Chemello and Giannuzzi-Savelli (Atlas of Mediterranean Nudibranchs) write the max. known length is 70mm. The smallest individual I met (ek112914) had a length of 67mm, the largest 124mm.
Data:
ek112306: July 25, divesite "La Piscina", depth 19m, size 82mm
ek112914: July 28, divesite "La Payita", depth 14m, size 67mm

Dear Erwin,
I use to confuse the names Platydoris argo with Archidoris pseudoargus but with your photos of the former, and the recent discussion about Archidoris pseudoargus, I shouldn't do that again.

I have posted your interesting series of photos showing P. argo 'trailing' like in species of Risbecia, as a separate message.

Best wishes,
Bill Rudman.
