The<unk>  are a major group of amoeboid protozoa, including the majority that move by means of 
internal cytoplasmic flow.  Their pseudopodia are characteristically blunt and finger-like, 
called lobopodia.  Most are unicellular, and are common in soils and aquatic habitats, with some found as symbiotes 
of other organisms, including several pathogens.  The<unk>  also include the slime moulds, multinucleate or 
multicellular forms that produce spores and are usually visible to the unaided eye.<unk>  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 
its size is often studied as a representative cell.  Multinucleate amoebae like Chaos and 
Pelomyxa may be several millimetres in length, and some slime moulds cover several square feet.
