Deciphering the Greek roots results in defining protozoa as "first' (proto) 'animals' (zoa). Generally protozoa are unicellular organisms with a few species exhibiting colonial forms. For the most part the protozoa can be distinguished from other unicellular eukaryotes. However, sometimes confusion and controversy do occur. The protozoa are a very diverse group and it is difficult to formulate definitions and descriptions which will include the majority of this group. Protozoa exhibit a wide variety of morphologies. There is no one shape or morphology which would include a majority of the protozoa. Shapes range from the amorphous and ever-changing forms of amoeba to relatively rigid forms dictated in part by highly ordered cytoskeletons or secreted walls or shells. Protozoa are found virtually everywhere. As a group, the protozoa are extremely adaptable, individual species, though, generally have very specific niches. Like all other organisms, protozoa must be able to acquire and metabolize nutrients from their environment.
