An active amoeba

An amoeba 100 microns in length actively moves using its many slender pseudopodia. In the cytoplasm, we can see a contractile vacuole and numerous particles that were probably captured as food.


Commentary by Prof. Yuji Tsukii, Hosei University
This is Vexillifera, a comparatively large amoebae. The shape and color of the cell body are similar to Mayorella, but unlike Mayorella, it extends several long, thin pseudopodia called dactylopodia.
