In several classification systems proposed by Thomas Cavalier-Smith and his collaborators since 1981, Protozoa is ranked as a kingdom. The seven-kingdom scheme proposed by Ruggiero et al. in 2015, places seven phyla under Protozoa: Euglenozoa, Amoebozoa, Choanozoa, Loukozoa, Percolozoa, Microsporidia and Sulcozoa.rotozoa, as traditionally defined, are mainly microscopic organisms, ranging in size from 10 to 52 micrometers. Some, however, are significantly larger. Among the largest are the deep-sea dwelling xenophyophores, single-celled foraminifera whose shells can reach 20 cm in diameter.
