Conchophthirus was deciliated by calcium ion shock followed by shearing through a micropipette. This revealed the location of the deciliated basal bodies and the cell's surface architecture. In this image of the left side ciliaturethe thigmotactic ciliature is revealed at the suture line. Also note that, when zoomed in, in this preparation the clathrin coated pits, which are normally an invagination into the cytoplasm have everted following the deciliation procedure, to form a small evagination anterior to the stubb of each deciliated basal body.

This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20kV. The negative magnification is 1060X. The raw film was scanned with an Epson Perfection V750 Pro. This image is available for quantitative analysis.
