  1. 1. Animal Like Protists Phylum Sarcomastigophora Phylum Apicompleza Phylum Ciliophora
  2. 2. Protists <ul><li>Over 38,000 species of protists! </li></ul><ul><li>Members of the original life forms on earth! About 1.5 billion years ago! </li></ul><ul><li>Some protists are plant like, some are animal like </li></ul><ul><ul><li>Protozoa: animal like protists </li></ul></ul><ul><li>Many have symbiotic relationships: </li></ul><ul><ul><li>Parasitism </li></ul></ul><ul><li>Scientists who study only protists: protozoologists </li></ul>
