"Ward's Phenomena"

Specially Prepared “Real-Life” Combinations
The world is teeming with a wide variety of micro life, making studying samples of pond water complicated especially for the beginning student. To lessen the confusion, Ward's has prepared different culture mixes that reflect protist combinations that occur in the real world, yet eliminates the hundreds of other life-forms found in a collected sample.

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

Examples of Organisms That Grow in Colonies

Lives in intestine of host — mealworms — as symbiotic organism. Culture of mealworms provided.
