Amoeba crawling on a glass slide. This picture was taken with a light microscope laid sideways in the table, and the amoeba was inside a very tiny handcrafted fishbowl (amoebabowl?)

Single cell, living, moving to upper right. The uroid is the cumpled region at the posterior end of the cell. Actively progressing pseudopodia (such as the one pointing north) have a hyaline cap. Cell surface with folds. Contractile vacuole and nucleus not visible.
-
Image of live cell capturing Euglena gracilis cells. Even though the amoebae move considerably slower than the flagellates, the flagellates cluster around the amoeba and are ingested.
-
The posterior end of most moving lobose amoebae has a different appearance to the rest of the cell. In the case of Amoeba proteus, it looks crumpled. This is in part due to the interactions of actin and myosin that cause the forward movement of the cell.
-
Amoeba proteus with numerous crystals showing typical polypodial movement. The specimen was gathered in a tiny freshwater pond at the island of Hiddensee (Baltic Sea, Germany) which shows a fascinating biodiversity of naked and testate amoebae. Images were taken using Zeiss Standard with Olympus C7070 CCD camera.

Nucleus (center) and trailing uroid (upper left) of Amoeba proteus. To the right of the nucleus there are several food vacuoles. In addition many tiny crystals are visible. The specimen was gathered in a tiny freshwater pond at the island of Hiddensee (Baltic Sea, Germany) which shows a fascinating biodiversity of naked and testate amoebae. Images were taken using Zeiss Standard with Olympus C7070 CCD camera.
