Amoebozoa

Life > Eukaryotes

The term "amoeba" is nowadays recognised as representing a type of cellular organisation, rather that a monophyletic group. An amoeba has only one cell (unicellular) and is characterised by the way it moves by squeezing its protoplasm into temporary leg-like extensions called pseudopodia.

Classification

Acramoeba

 

Archamoebae

 
 

Entamoebidae

 
   

Entamoeba

Members of this genus are internal parasites or commensals of animals. Entamoeba histolitica causes the death of 50 000 to 100 000 people annually.

Mastigella

 
 

Pelomyxidae

 
   

Pelomyxa

Single-celled. Have no mitochondria but instead have symbiotic bacteria that seem to perform a similar function thus illustrating how mitochondria might have started out prior to their total integration into the cellular machinery.

Formerly classified in the Rhizopoda (amastigote amoebas), which has now been disbanded because it is polyphyletic.

Tubulinida (including Poseidonida)

Based on the phylogeny of Lahr et al. (2013), I have collapsed Amoebidae, Hartmannellidae and Poseidonida into this monophyletic group because of various phylogenetic issues with keeping these groups separate. Tubulinida as defined here is the sister group of Arcellinida.
