Protozoa (meaning first animals) are heterotrophic, single-celled or colonial eukaryotes. Individuals are microscopic and range in size from a few to hundreds of micrometers, depending on the species.eyond this broad description, it is difficult to define protozoa because they are so diverse and only distantly related to each other. While the term protozoa is commonly used, it has little basis in evolutionary history, or phylogeny, of these organisms.
