ciliary rows
Description:
Pelagovasicola (pee-ladge-o-vee-sick-o-la) cinctum is a very fast swimming obovoid ciliate measuring 50 - 180 X 40 - 85 microns. It is common in plankton of lakes and ponds. The body is surrounded by 5-7 distinct ciliary girdles. The posterior fifth of the cell is unciliated. The contractile vacuole lies in the posterior end and has about 20 radial collecting channels. The macronucleus is kidney-shaped and lies in the mid-body. Extrusomes are arranged in the margin of the oral dome, occasionally extruded as bundles of fine filaments. This slightly squashed specimen was collected in the plankton of a bog pond near Konstanz, Germany, and this images emphasizes the characteristic rows of basal bodies ciliary girdles (arrows). Differential interference contrast.
