Diversity of Planktonic Ciliates in the Bay of Villefranche

Oligotrichs: a large Strobilidium-type (A), mixotroph Laboea strobila (B), Strombidium-type oligotrichs of various sizes (C,E,F,G,H,J), and mixotroph Tontonia-types (D,I). The symbiont-bearing prostomid Tiarina fusus (L), tintinnid Stenosomella ventricosa (M), tintinnid Dadayiella ganymedes (N), prostomid Balanion (O); the predatory ciliate Didinium (K), the mixotrophic haptorid Mesodinium rubrum (P) and a peritrich (Q) perhaps a single cell of Zoothamnium pelagicum.
