Etymology

Malleolus comes from the Latin malleus 'hammer' with the ending -olus 'little', so it means 'little hammer'. Scientists gave the same name to a tiny, fan- or hammer-shaped organ on some arachnids because it is a small, knob-like part that helps the animal sense vibrations and chemical cues.
