The word protozoa (singular protozoon, or protozoan) was coined in 1818, by zoologist Georg August Goldfuss, as the Greek equivalent of the German Urthiere, meaning primitive, or original animals. Goldfuss erected Protozoa as a class containing what he believed to be the simplest animals.Originally, the group included not only microbes, but also some lower multicellular animals, such as rotifers, corals, sponges, jellyfish, bryozoa and polychaete worms.oldfuss erected Protozoa as a class containing what he believed to be the simplest animals.
