amoeba

Blob under microscope

An amoeba is a single-celled organism that moves by extending temporary projections of its body, flowing into new shapes rather than using fixed appendages.

Found in water and soil, amoebas are studied in biology as examples of simple life.

Figuratively, something amoeba-like shifts shape or boundaries unpredictably: The company's structure was amoeba-like, constantly reorganizing.

Also spelled amoeba (American) or amoeba (British).
