Infraciliature of Pelagothrix plancticola (FOISSNER,BERGER&SCHAUMBERG,1999).The three green arrowheads mark the three rows of dikinetids comprizing the adoral organelles or "dorsal brush".The rightmost adoral organelle is continuous posteriorly with a shortened somatic kinety.The pink arrowhead marks one of the dikinetids of the undulating membrane that borders the oral aperture.Specimen collected from an ephemeral freshwater puddle on the bank of the Boise river in Boise,Idaho.April 2007. Stained by the silver carbonate technique (Foissner,W. Europ. J. Protistol.27:313-330;1991).Brightfield.
