ameba
Shapeless microscopic life
Ameba is an alternate spelling of amoeba—a single-celled organism that moves by extending temporary projections of its body.
The spelling without the o reflects the word's pronunciation and appears in some scientific contexts, though amoeba remains more common.
The ameba engulfed its prey.
