Description:

Vannella (van-ell-a), naked free-living amoeba, moves with a single pseudopodium directed forwards (i.e. is unipodial). Hyaline region very extensive. Posteriorly, the uroid is just a stiffened region of cytoplasm. Contractile vacuole and nucleus evident. Consumes bacteria. Very similar to Platyamoeba, distinguished usually by the slightly broader aspect. Phase contrast.
