Paraquadrula Deflandre 1932

Paraquadrula irregularis test. This amoeba is a member of the Arcellinida. The test is round when viewed en-face (the view in these images) and ovoid in the lateral view. The test is composed of secreted rectangular calcite plates cemented into slightly irregular rows. The pseudostome is a broad oval shape (located towards the bottom in in these images). Although the test plates are similar in appearance to those of Quadrulella the plates are siliceous in the latter and the test of Quadrulella is pyriform with a distinct neck. Feeds on algae. From freshwater pond near Boise, Idaho. Oblique illumination.

Paraquadrula irregularis - a member of the Arcellinida. The test is round when viewed en-face (the view in these images) and ovoid in the lateral view. The test is composed of secreted rectangular calcite plates cemented into slightly irregular rows. The pseudostome is a broad oval shape (located atowards the bottom in in these images). Although the test plates are similar in appearance to those of Quadrulella the plates are siliceous in the latter and the test of Quadrulella is pyriform with a distinct neck. Feeds on algae. From freshwater pond near Boise, Idaho. Phase contrast.

Paraquadrula builds its scales from calcite, which is birefringent. This is the reason why in DIC (polarized light) they show such different magnitudes. Scale bar indicates 10 µm. Sample from a bog near Reith/Pillersee (Tyrol, Austria). The image was built up using several photomicrographic frames with manual stacking technique. Images were taken using Zeiss Universal with Olympus C7070 CCD camera.Image under Creative Commons License V 3.0 (CC BY-NC-SA).
