A genus of single-celled organisms (protozoans) that live in water and have a protective shell-like covering.
Modern Latin scientific name, likely derived from Latin 'arcus' meaning 'arch' or 'bow', referring to the arc-shaped shell structure of these organisms.
Under a microscope, Arcella looks like a tiny transparent dome with a little creature inside—it's one of nature's original space suits, letting these microorganisms protect themselves while still exploring their watery world.
