Cashia (cash-ee-a) - tentative identification - small limax (slug-shaped) amoeba, hyaline cap to right lacks inclusions, contractile vacuole is associated with the posterior end of the cell. Phase contrast.

Cashia. Cell observed in freshwater sediments in the vicinity of Broome, Western Australia in September 2003. This image was taken using phase contrast optics. This work was supported by the Australian Biological Resources Study.

Saccamoeba (sack-a-me-ba), a monopodial naked free-living amoeba. With a lobose pseudopodium, usually progressing as a single pseudopodium (i.e. is monopodial). Hyaline cap absent or not well developed. Small uroid. These cells also with light-coloured contractile vacuoles and with nuclei with nucleoli. Phase contrast.

The identity of this amoeba is uncertain. It is a amoeba that forms lobose pseudopodia and has a large nucleus. This cell is squashed and has taken on this star-like form. Phase contrast microscopy.

Detail of Polychaos dubium, a large polypodial naked amoeba. P. dubium is the type species. Palmate form. Pseudopodia lack the longitudinal ridges seen in Amoeba species. The posterior is composed of a collection of fused remnant pseudopodia. May become monopodial during rapid locomotion. The granular nucleus is spherical to ovoid in shape. The cytoplasm contains ingested algae and numerous refractile crystals. This image shows a large bipyramidal cytoplasmic crystal, probably composed of urea. From freshwater pond near Boise, Idaho. DIC optics.

Portrait of Polychaos dubium, a large polypodial naked amoeba. P. dubium is the type species. Palmate form. Pseudopodia lack the longitudinal ridges seen in species of Amoeba. The posterior (left side of image) is composed of a collection of fused remnant pseudopodia. May become monopodial during rapid locomotion. The granular nucleus is spherical to ovoid in shape. A large contractile vacuole is visible. The cytoplasm contains ingested algae and numerous refractile crystals. From freshwater pond near Boise, Idaho. DIC optics.
