Hay medium. Characterized by cilia; nearly all possess two types of nuclei.

Two flagella; no chloroplasts. Food organism. Hay medium.

Characterized by flagella; lacks plastids.

Test cylindrical, covered with sand granules. Soil-water medium.

Characterized by pseudopods; with or without a shell (test).

Predatory. Feeds on Paramecium caudatum. Hay medium.

Characterized by cilia; nearly all possess two types of nuclei.

Usually found in freshwater and mosses, this organism has a hard umbrella shaped shell or "test", out of which finger-like pseudopodia project.

With stiff 'arms' radiating in all directions, these microscopic organisms look like sea urchins

Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp. Found in woodland soil in decomposing vegetation where bacteria are abundant. Incubation temperature 25°C. Plate cultures grown with Enterobacteria as food source; freeze-dried cultures include food source.

Characterized by an amoeboid stage (lacking cell walls) and a fungus-like reproductive structure.

Very large ciliate. Feeds on colpidium. Hay medium.
Characterized by cilia; nearly all possess two types of nuclei.

Pink to bright rose color.
Characterized by cilia; nearly all possess two types of nuclei.

Members of the Pelomyxa genus look very much like Amoeba. Pelomyxa, however, have many nuclei, whereas Amoeba have only one.
