Very characteristic for the plankton of the Mediterranen sea are the tintinnid ciliates (about 70 species).
The lorica ("house") of this ciliate was about 260 µm long.
I dont know the species. Somebody can help me?

for René,
I did not discover any differences around the lorica opening (see picture).
Yesterday I read that there are three different forms of the lorica in one lifecycle of Favella ehrenbergii: the Favella form, the Coxliella form and the Decipiens form (cfr. Wolfgang Petz and Andreas Leitner, in: R. Hofrichter, Das Mittelmeer II/1, p. 118).
Is it possible that "my" Favella has the Decipiens form?

Hi Franz,
Do you know the plankton identification leaflets ("Fiches d’Identification du Zooplancton") produced by ICES ?
These can be downloaded as pdfs from
http://www.ices.dk/products/idleaflets.asp
Sheets 117-127 cover the tininnids, with sheet 121 for Favella spp.
Just looking at the pictures, I would go for Favella markusovszkyi (what a great name!) - but that is not very scientific of me !
It would appear to me that your specimen has no "rings"/spirals near the mouth of the lorica and this may be key to its identification.
Boa sorte

Hello Franz,
Brian essentially used the same literature as I did, F.markusovszkyi is certainly very close. It seems your form has a bigger lorica opening then mentioned in the text. It is reported for the North Sea in any case.
I have no access to Hofrichter, but other sources (http://books.google.nl/books?id=5n9Gc0k ... q=&f=false) show the coxliella and decipiens form with ring like structures in the lorica.
Again, nice work, hope to see more!
