Differential interference contrast image showing pseudpodia of living cell.

Image of Arcella cell sitting stop an air bubble.

This image was taken with a scanning light microscope. The texture of the test is visible around the edge of the cell. Three nuclei are also visible.  

This is a DIC image that shows the central position of the aperture.

Detail of test structure captured by SEM. Notice honeycomb.

This testate amoebae was collected from a White Cedar Swamp in Woods Hole, MA. Note the areolate pattern on the test. Image by Dan Lahr.
