of other organisms, including several pathogens. The Amoebozoa also include the slime moulds, multinucleate or

Amoebozoa vary greatly in size. Many are only 10-20 μm in size, but they also include many of the larger

protozoa. The famous species Amoeba proteus may reach 800 μm in length, and partly on account of
