The psuedopodia come out through the windows. Zoomastigotes contain at least on flagellum. Like amoebas, most are harmless, however, not all. These organisms are responsible for causing Giardia. Trypanosomes are parasites found in the blood that cause such things as African Sleeping Sickness.
Zoomastigotes are the ancestors to the animal kingdom.
Collar flagellates are considered the missing link. Plasmodial slime mold is basically one big amoeba. It is a naked mass of protoplasm that feeds on bacteria and organic matter. When they reproduce they form a mushroom-like reproductive structure. Cellular slime mold superficially resemble amoebas.
