The species Euglena gracilis, has been used extensively in the laboratory as a model organism. Most species of Euglena have photosynthesizing chloroplasts within the body of the cell, which enable them to feed by autotrophy, like plants. However, they can also take nourishment heterotrophically, like animals. https://www.youtube.com/watch?v=zVNOqI6pc9k
