Locomotion:cilia. cilia. Animal-Like Protists:. The Protozoa. Evolutionary Perspective of the Protists. The protists are a polyphyletic group that arose about 1.5 billion years ago when the Archaea and Eukarya diverged.. Our understanding of the evolutionary relationships among protists is currently in flux . This lab will tax your skills as a microscopist. Have patience and ask me for assistance if required. First, we will focus on the Ciliates, the Sarcodinids (Ameobas), the non-parasitic Flagellates zooflagellates. The third type of protozoan's are called zooflagellates.. It is an animal like protist that has flagella.. Most of the zooflagellates have one to eight flagella, to help them move.. Many of the zooflagellates live inside other organisms. Ex: Inside the intestines of termite.. Not quite an animal but close enough . Phyla. Sarcomastigophora. Flagellate. Ameboid. . Ciliophora. ciliates. Apicomplexa. sporozoans. .
