The amoeba proteus is commonly known as the amoeba, the ciliophora are commonly known as ciliates, and the zoomastigina are commonly known as zooflagellates. There are currently more than 200,000 species of protists that have been discovered and documented, and many more have yet to be discovered.
Protists are found pretty much anywhere that water is found. They range from microscopic, single-celled organisms all the way up to large seaweed plants. They are typically seen as the basis of any ecosystem, as they either create energy through photosynthesis which moves up the food chain, or they are eaten themselves and provide energy for many other living creatures. The kingdom Protista poses a problem for scientists because of how vast and diverse it is. The organisms vary greatly in many different categories, and are simply defined as any eukaryote that is not an animal.
Along with their scientific names, many protists also have common names. For example, the name "amoeba" is given to any of the members of the rhyzopoda phylum. While a lot of the names of protists are not commonly known, they may be known for other reasons. For instance, plasmodium is the protist that causes malaria, and giardia lamblia is the protist that causes giardiasis. Many commonly known diseases are a result of ingesting specific protists.
