Protozoa vary in size from 1/5,000 to 1/50 of an inch in diameter. They can be classified into three general groups based on their shape. One group is the Ciliates, which are generally the largest protozoa. They have hair-like projections called cilia and they eat the other two types of protozoa as well as bacteria. The second group is the Amoebae. The third group is the Flagellates, which are usually the smallest of the protozoa and have one or several long, whip-like projections called flagella extending from their cells.
