Euglenozoa
Euglenozoa include a variety of common free-living species, and some important parasites, of which a few infect humans. There are two main subgroups, the Euglenoidea "euglenids" and Kinetoplastea "kinetoplastids". Euglenozoa are unicellular, mostly around 1540 µm in size, although some euglenids get up to 500 µm long.
