Description:

Nuclearia, filose amoeba. Differential interference contrast. This cell has been feeding on yeast cells. Thin filose pseudopodia, without any evident internal skeletal elements, extend from the front of the cell, and are pulled in at the back. The contractile vacuole with surrounding vesicles is located at the rear of the cell. The nucleus with the round nucleolus lies just anterior to the contractile vacuole.
