Amøben er et halv millimeter stor protozo, som er opbygget af én celle. Amøber klassificeres i øjeblikket under protister under protozoer, men klassificeringen bliver ændret når en bedre forefindes.
Amøben er meget almindelig i danske Søer. Den lever frit i vand eller som parasit, et eksempel på en parasitisk amøbe kunne være Entamoeba histolytica.
I 2008 blev en en-cellet 2,5 cm stor kugleformet amøbe Bahamian Gromia fundet ved Bahamas nær ved Little San Salvador Island. Den bevæger sig ved at rulle henover havbunden. [1]

Retrieved December 7, 2008 Citat: "...The grape-like animal, tentatively named the Bahamian Gromia, is actually a single-celled organism, fully one inch long...But what makes it really fantastic is that it moves -- very slowly -- by rolling itself along the ocean floor...Matz worked out the genetics of the new creature and found it's a giant amoeba closely related to similar blobs found in the Gulf of Oman, near Antarctica, off Guam, and in the Mediterranean. None of them are known to move..."
