Amoeba

/əˈmiːbə/ noun

Definition

A tiny single-celled organism that lives in water and soil, can change shape, and moves by creating temporary arm-like extensions.

Etymology

From Greek 'amoibē' (change/exchange). Named by scientist Christian Ehrenberg in 1830 because the organism's constantly changing shape exemplifies the idea of continuous transformation.

Kelly Says

The amoeba's name is Greek for 'change' because it literally never stays the same shape—it's constantly flowing and morphing, which is why early scientists found it so fascinating and named it after the very concept of change itself!
