Paramecium bursaria is a ciliate that contains mutualistic algae called Zoochlorella. The algae lives in the cytoplasma of the Paramecium and provides it with food. Paramecium bursaria grows in Dilute Alfalfa Medium (Hay Medium) or Soil Water Medium. Requires light for growth.

Paramecium aurelia is the smallest species of Paramecium we offer. Paramecium aurelia is characterized by cilia, which it uses for locomotion and feeing. Contains a macronucleus and two micronuclei. Grows in Dilute Alfalfa Medium (Hay Medium).

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

This organism is easily recognized by its trumpet-shape, and can commonly be found in freshwater ponds and streams. It reproduces by budding.

Volvox aureus is a species of colonial green algae that forms spherical colonies of cells.

Paramecium multimicronucleatumis one of the largest species of Paramecium. This ciliate contains a single macronucleus and four or more micronuclei. Grows in Dilute Alfalfa medium (Hay Medium).

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