Favorinus sp.? from Turkey

October 30, 2001
From: Baki Yokes


Dear Bill,

Here is another species which saw for the first time, in the sea of Marmara, Istanbul. The colour and shape of the rhinophores suggest a Favorinus species. They are found below 25m of depth and on rock surfaces. Can you identify it? Thank you in advance.

Dear Baki,
Certainly the swelling on the rhinophores which can be seen in the upper photo is suggestive of a species of Favorinus but the arrangement of the cerata in closely packed rows, and the coiled inner cerata [see inset] are more typical of one of the hydroid feeding genera like Phidiana.

I asked Bernard Picton for his opinion on your photos and he has identified it as Pruvotfolia pselliotes (Labbe, 1923), an identification with which I totally agree. As he says in his separate message, this is probably the first Mediterranean record of this animal which was known previously only from the Atlantic coast of France. This is another very interesting find.

Best wishes,
Bill Rudman
