The plural form of amoeba using the English '-s' ending, referring to multiple amoeba organisms.
From 'amoeba' (Greek 'amoibē', change) plus English plural suffix '-s'. In modern English, this '-s' plural is more common than the classical '-ae' plural in informal usage.
The fact that we have both 'amoebae' and 'amoebas' shows how English is gradually replacing Latin plurals with regular English '-s' plurals—in 100 years, 'amoebas' might be the only form people use.
