Etymology

Tardigrade comes from Latin parts tardus 'slow' and gradus 'step', so it literally means 'slow step'. Think of tardy and gradual to remember it: a tardigrade is a tiny 'slow walker' you can see under a microscope, which helps you picture this small water animal famous for surviving very harsh places.
