Here's why:
* Zoomastigina is a diverse group of protists that includes many species that move using one or more flagella. Some notable examples include:
* Trypanosoma, which causes sleeping sickness in humans
* Giardia, a common intestinal parasite
* Euglena, which has both plant-like chloroplasts and animal-like flagella
Other phyla of protists:
* Ciliophora use cilia for movement, which are much shorter and more numerous than flagella.
* Sarcodina move by extending pseudopods, or "false feet."
* Sporozoa are non-motile and parasitic.
Let me know if you'd like to know more about any of these protist phyla!
