Historically, protozoa were defined as single-celled organisms with animal-like behaviors, such as motility and predation. The group was regarded as the zoological counterpart to the  protophyta , which were considered to be plant-like, as they are capable of photosynthesis.The terms protozoa and protozoans are also used informally to designate single-celled, non-photosynthetic protists, such as ciliates, amoebae and flagellates.amiliar examples of protists with a pellicle are the euglenoids and the ciliate Paramecium. In some protozoa, the pellicle hosts epibiotic bacteria that adhere to the surface by their fimbriae or attachment pili .
Protozoa: Protozoa. The word protozoa means little animal. They are so named because many species behave like tiny animals, they hunt other microbes as food. Protozoa mainly feed on bacteria, but they also eat other protozoa,and sometimes fungi. Some protozoa absorb food through their cell tissues. Others,surround food and engulf it.
