G. delicatula cells are cylindrica, with flat valves. Each cell as a spine extending from the valve margin. This spine fits into a depression on the adjacent cell to form chains. Few but large chromatophores are present usually at the cell periphery. This species can form large blooms in the spring and early summer

Amphitrema (am-fee-tree-ma) a testate amoeba with an organic test with (unusually) two apertures at opposite poles of the test. This empty test found among moss at the margins of the lake. Differential interference contrast.

Chaetoceros socialis (key-toss-err-oss sew-see-ah-liss), a centric diatom in with long spines. In this species dozens or hundreds of cells are linked loosely together by their spines. Common in marine ecosystems. Dark ground.
-
Chain of Porosira glacialis. Note that the delicate spines are chitinous. Focus on frustule surface. Scale bar indicates 50 µm. The image was built up using several photomicrographic frames with manual stacking technique. Sample from North Sea near Heligoland (spring diatom bloom). Images were taken using Zeiss Universal with Olympus C7070 CCD camera.
