Re: What are the taxonomic classification of the species Amoeba proteus?

Melody:
 Here is a complete classification scheme from the Society of 
Protozoologists illustrated guide book:  (There are others!)

Phylum Sarcomastigophorea  (includes flagellates and amoeba, but not  
   ciliates, apicomplexans, and others)  (BTW: now that it is known that 
   apicomplexans, including Malaria, are related to ciliates and 
   dinoflagellates, this classification will/has changed a bit!)

Subphylum Scarcodina (separate from flagellates and opalinids)

Superclass Rhizopodea (separate from Actinopodea, with Radiolarians, etc)

Class Lobosea (solitary cells, broad pseudopodia, not filamentous filopodia 
or inter-connecting reticulopodia)

Subclass Gymnamoebia (separate from Testacealobosia, amoeba with shells)

Order Amoebida (amoeba with mitochondria, no flagellar stage)

Suborder Tubulina (cylindrical body shape, separate from flattened amoeba 
with a firm pellicular layer and triangular cells)

Family Amoebidae  (polypodial, separate from Entamoeba that have only one 
pseudopod)

Genus Amoeba, with only one nucleus and with somewhat ridged pseudopodia 
(other genera include Chaos (with 1000 nuclei!), Trichoamoeba, Hydromoeba, 
Polychaos)

There are other classifications schemes, (since amoeba can be very 
difficult to identify) i.e. with many more phyla, so one must take these 
classifications with a grain of salt: they will be changed again and again, 
expecially as DNA-based classification matures.

No doubt the second edition of this book by the Soc. of Protozoologist will 
be different from the first.  (BTW, I recently designed the cover for this 
new book, which will be printed sold later this year!)
